Five Egyptian cotton genotypes (Australian, BBB, G97, G92 <br/>and G96) were used as parents in this study. Three of these <br/>varieties were long staple, BBB (big black boll) (P1), Australian <br/>(P2) and G97 (P3) while the other two varieties were extra-long <br/>staple, Giza 92 (P4) and G96 (P5).<br/>Diallel mating design was used to produce 10 single crosses <br/>and 15 double crosses across two seasons (2016 and 2017) at the <br/>Agricultural Experiments and Research Station, Faculty of <br/>Agriculture, Cairo University, Egypt. The final experiment was <br/>conducted in the third growing season (2018) using alpha lattice <br/>design (5 x 6) to evaluate 30 genotypes (parents, single crosses and <br/>double crosses) at Sakha Agricultural Research Station, Agriculture <br/>Research Center, Egypt.<br/>The present study was therefore, designed to: <br/>(1) Generate new forms of cotton genotypes having high seed <br/>cotton yield potential and one or more desired of traits. <br/>(2) Characterize the desirable traits and existing cotton parents and <br/>their crosses for early maturity and determine the <br/>interrelationship between early maturing, yield and fiber <br/>quality traits. <br/>(3) Determine various genetic parameters for yield, its components <br/>and quality traits in crosses of Egyptian cotton. <br/>(4) Estimate the efficiency of alpha lattice and restricted maximum <br/>likelihood models (REML) analysis in increasing the precision <br/>of the present trials. <br/>110<br/>First Season<br/>In first season 2016, the five parents were planted and mated <br/>in a diallel mating design excluding reciprocals to obtain 10 single <br/>crosses. Seeds from each parental genotype were sown in two rows <br/>for each parent. The row was 7 meters long and 60 cm apart and <br/>distance of 70cm between the plants on hills. Later the plants were <br/>thinned to one. Emasculation and crossing were made between the <br/>parents at flowering stage.<br/>Second Season<br/>In the second season 2017, F1 single crosses were grown to <br/>mate in a diallel mating design to produce double cross seeds with <br/>the restriction of no parent appeared twice in the same double cross <br/>combination to obtain 15 double crosses.<br/>Third Season<br/>In the final experiment (third season 2018), alpha lattice <br/>design (5x6) with three replications was used in evaluating 30 <br/>genotypes (the 5 parental genotypes, 10 F1`s single crosses and 15 <br/>double crosses). Each plot consisted of two rows. The rows were 4 <br/>meters long and 65 cm apart. Hills were spaced at 20 cm within <br/>rows and seedlings were thinned at two plants/hill. All cultural <br/>practices were followed throughout the growing season as usually <br/>done with ordinary recommendations for cotton culture.<br/>111<br/>The Studied Traits<br/>(1) Seed cotton yield/kentar (SCY/K), (2) Lint cotton <br/>yield/kentar(LY/K), (3) Boll weight (g) (BW), (4)Number of open <br/>bolls/plant (NO.B/P), (5) Lint percentage (%) (L%).<br/>Earliness traits<br/>(1) First fruiting node of first sympodium (F.F.N), (2) Days to first <br/>flower appearance (D.F.F), (3) Duration of the boll maturation <br/>(day).<br/>Fiber properties<br/>(1)Upper half mean (U.H.M), (2) Fiber strength (F.S), (3) <br/>Micronaire value (Mic). <br/>Statistical Analyses<br/>Statistical procedures for alpha lattice design were <br/>conducted according Cochran and Cox (1957). Ordinary Reml <br/>model analysis was described by Hough et al. 2010 and Piepho et <br/>al., 2012. Data were analyzed using Genstat (2011).<br/>The procedures of single crosses analysis were described by <br/>Griffing (1956) based on method 2, model I (fixed model) as <br/>outlined by Singh and Chaudhary (1985). The procedures of double <br/>crosses analysis (quadriallel) were carried out according to the <br/>procedure outlined by Singh and Chaudhary (1985). The GCA <br/>effects of parents and SCA effects of F1 crosses were calculated <br/>according to the method described by Griffing (1956) based on <br/>method 2, model I (fixed model) as outlined by Singh & <br/>112<br/>Chaudhary (1985). Estimates of heritability were determined <br/>according to the equations of Mather & Jinks (1982). <br/>The results could be summarized as follows:<br/>1. Earliness Traits<br/>1. Line general was highly significant (P≤ 0.01) for all traits <br/>suggesting the presence of the additive variance in the <br/>inheritance of these traits subsequently selection would <br/>be efficient in improvement these traits. Also, 2- line <br/>arrangement was highly significant (P≤ 0.01) for all <br/>traits, excluding days to opening 1st boll which was <br/>significant only (P≤ 0.05) suggesting the presence of the <br/>non-additive variance in the inheritance of these traits. <br/>Also, 3- Line arrangement was highly significant (P≤ <br/>0.01) for all traits excluding for days to opening first boll <br/>which was significant only (P≤ 0.05) indicating the <br/>contribution of the additive by dominance interaction <br/>including all three factors or higher order interaction <br/>except all dominance types.<br/>2. Highly significant differences for mean squares of P, C, <br/>D, P vs. C and P vs. D (P≤0.01) for all earliness traits. P <br/>vs. S was insignificant for position of first fruiting node <br/>and days to opening first boll and P vs. D was <br/>insignificant for position of first fruiting. Highly <br/>significant differences for mean squares of P, C, D, P vs. <br/>C and P vs. D (P≤0.01) for all earliness traits. <br/>113<br/>3. Double cross [(BBBxG97)(G92xG96)] was the earliest<br/>for position of first fruiting node and days to first flower <br/>and showed negative and significant mid parent heterosis <br/>with significant different from [(AustralianxG96) <br/>(BBBxG97)].<br/>4. Alpha lattice design was more efficient than conventional <br/>RCBD for most of studied traits and means are adjusted <br/>for block effects. Lowest values for CV and SE for traits <br/>were calculated by ordinary REML reflecting the <br/>accuracy and precision of this method compared to <br/>ANOVA for estimating variance components<br/>5. GCA mean squares were significant for both F1 and DC <br/>in all earliness traits except for days to first flower. SCA <br/>mean squares were highly significant only for F1 in two <br/>traits first fruiting node and days to first flower. <br/>GCA/SCA ratio revealed that GCA was higher than SCA <br/>in F1 for duration of the boll maturation while in DC, it <br/>was higher than SCA for first fruiting node and days to <br/>opening 1st boll.<br/>6. 4-line interactions with respect to particular arrangement <br/>of the parents in double crosses, (P1xP3) (P4xP5) was <br/>the best combination for all earliness traits.<br/>2. Yield and Yield Traits<br/>1. Genotypes included in the study had highly significant <br/>variation (p≤0.01) for all studied traits. genotypes was <br/>partitioned into parents (P), single crosses (S), double <br/>114<br/>crosses (D), P vs. S and P vs. D. ALL previous parts (i.e. P, <br/>S, D, P vs. Sand P Vs. D) exhibited highly significant <br/>differences (p≤0.01) for all studied traits, except lint <br/>percentage (L %) due to P and D. Also, P vs. S was <br/>insignificant for seed and lint cotton yield/kentar and P vs. <br/>D was insignificant for lint cotton yield/kentar.<br/>2. Line general was highly significant (p≤0.01) only for No. <br/>of bolls/plant and boll weight suggesting the presence of the <br/>additive variance in the inheritance of these traits <br/>subsequently selection would be efficient in improvement <br/>these traits, whereas it was significant (p≤0.05) only for seed <br/>cotton yield/kentar. Meanwhile, line general was <br/>insignificant for lint cotton yield/kentar. 2-line arrangement <br/>was highly significant (p≤0.01) for all traits except for lint <br/>percentage (L%) suggesting the presence of the non-additive <br/>variance in the inheritance of these traits. 3-line arrangement <br/>was highly significant (p≤0.01) for all traits except for lint <br/>percentage (L %) indicating the contribution of the additive <br/>by dominance interaction including all three factors or <br/>higher order interaction except all dominance types. <br/>3. The double cross (AustralianxG92) (G97xG96) had the <br/>highest mean performance value and showed positive and <br/>significant mid parent heterosis for most of yield traits.<br/>4. Alpha lattice design was more efficient than conventional <br/>RCBD for most of studied traits except for boll weight.<br/>Lowest values for CV and SE for traits were calculated by <br/>115<br/>ordinary REML reflecting the accuracy and precision of this <br/>method compared to ANOVA for estimating variance <br/>components. Also results showed great differences between <br/>standard error for different traits under RCBD and standard <br/>error (SE) of the same traits under alpha lattice design. The <br/>smaller values of SE difference for alpha lattice design helps <br/>to detect smaller differences for the comparisons of mean. <br/>5. GCA mean squares were highly significant (P≤0.01) for <br/>F1 and DC in all yield traits except for Lint% which was <br/>insignificant with DC. Specific combining ability (SCA) <br/>mean squares were highly significant (P≤0.01) for F1 and <br/>DC in all yield traits except for Lint% with F1 and No. of <br/>bolls/plant with DC. GCA/SCA ratio revealed that GCA <br/>was higher than SCA in F1 for seed cotton yield, lint cotton <br/>yield, Lint % and boll weight while in DC; it was higher <br/>than SCA for seed cotton yield and No. of bolls/plant<br/>6. 4-line interaction with respect to particular arrangements <br/>of the parents in double crosses, (P1xP2) (P4xP5) and <br/>(P1xP3) (P4xP5) formed the best combination for most <br/>yield traits.<br/>3. Fiber Quality Traits<br/>1. Statistical analysis revealed that the genotypes <br/>included in the study had highly significant variation <br/>(p≤0.01) for all studied traits except for upper half <br/>mean which showed insignificance.<br/>116<br/>2. 1-line general, 2-line arrangement and 3- line <br/>arrangements, all the parts exhibited highly <br/>significant difference except upper half mean.<br/>3. Mean squares due to genotypes was partitioned into <br/>parents (P), single crosses (S), double crosses (D), P <br/>vs. S and P vs. D. Previous parts (i.e. P, S, D, P vs. S <br/>and P vs. D) exhibited highly significant differences <br/>(p≤0.01) for all studied traits. P vs. S was <br/>insignificant for fiber strength.<br/>4. Double cross [(AustralianxG96)(G97xG92)] had the <br/>highest mean performance for most traits and showed <br/>positive and significant mid parent heterosis<br/>5. Alpha lattice design was more efficient than <br/>conventional RCBD for most of studied traits and <br/>means are adjusted for block effects. Coefficients of <br/>variation (CV%) of alpha lattice design were low as <br/>compared to RCBD for fiber length and fiber <br/>strength. Lowest values of the coefficients of <br/>variation (CV%) for all traits and lowest standard <br/>error were recorded for reml analysis in fiber length <br/>and fiber fineness which indicates high experimental <br/>precision.<br/>6. GCA mean squares were significant for fiber length <br/>and fiber strength in F1, while GCA mean squares <br/>were significant for fiber strength and fiber fineness <br/>(Micronaire reading) in DC. Specific combining <br/>117<br/>ability mean squares were only significant for F1 in <br/>both traits fiber strength and fiber fineness <br/>(Micronaire reading). GCA/SCA ratio revealed that<br/>GCA was higher than SCA in F1 for fiber length <br/>while in DC, it was higher than SCA for fiber length <br/>and fiber fineness (Micronaire reading).<br/>7. For 4-line interaction with respect to particular <br/>arrangements of the parents in double crosses, the <br/>best combination was (AustralianxG97) (G92xG96).<br/><br/> |
