The results of this study can be summarized as follows:
First experiment: the interaction between gamma radiation doses and the cultivars showed, in the first generation
(M1) significant differences in the traits of plant height, number of leaves per plant, protein percentage and fiber
percentage. The highest value of plant height (87.6 cm) was for the Helaly cultivar at 15 Kr, followed by the
Khadrawy cultivar (87.1 cm) at 45 Kr in the 4th cut, and the highest value of the number of leaves (13.6) was for the
Helaly cultivar in the control treatment, followed by the Hatour cultivar (12.9) at the dose of 30 Kr in the 3 rd cut.
the interaction between gamma radiation doses and cultivars, in the second generation (M 2), showed significant
differences in plant height, number of leaves per plant, fresh yield, protein percentage, and fiber percentage. The
highest values for plant height (85.1 cm) were recorded for the Khadrawy cultivar at the dose of 30 Kr, followed by
the Hatour cultivar (82.4 cm) at 15 Kr in the 1st cut. The highest values for the number of leaves per plant were for
the Helaly cultivar (18.0) in the control treatment, which was significantly higher than all doses and cultivars in the
1st cut as well. The highest values for fresh yield (t. h-1) were recorded in the 4th cut for the Hatour cultivar (13.5) in
the control treatment, followed by the same cultivar (13.1) at the dose of 15 Kr, then the Khadrawy cultivar (12.4)
at 45 Kr.
second experiment :the study showed, in general, that the significant effects of the interaction between sodium
azide concentrations and varieties on the studied traits differs from the first generation to the second generation and
from one cut to another for the same generation and the same trait. the interaction between sodium azide
concentrations and cultivars, in the first generation (M1), indicated that significant differences for most of the
studied traits were in the fourth cut, for plant height, number of branches, number of leaves per plant, ratio of
leaves to stems (fresh and dry), and protein percent. The highest values in the fourth cut for plant height were for
the Khadrawy cultivar (97.2, 96.6 cm) at concentrations of 2000 and 1000 ppm, followed by Hatour (97.5 cm) at
3000 ppm. The highest values for the number of branches (71.3) were for the Helaly cultivar at 4000 ppm. The
highest values for the number of leaves per plant (28.4) were recorded for the Hatour cultivar at 4000 ppm,
followed by the Khadrawy cultivar (27.8, 28.2) at 3000 and 1000 ppm. While the interaction between sodium azide
concentrations and cultivars showed, in the second generation (M2), significant differences in the traits of number
of branches in the 2nd and 3rd cuts, number of leaves per plant in the 1st and 3rd cuts, protein percent in all cuts,
and fiber percent in the 1st , 2nd , and 4th cuts. The highest values for the number of branches (53.3) were recorded
for the Helaly cultivar at 1000 ppm in the 2nd cut, and for the Khadrawy cultivar (48.7) at 2000 ppm in the 3rd cut.
It is worth noting that the previous results of the interaction effect between the studied varieties and gamma ray
doses, or the interaction effect between the varieties and sodium azide concentrations show that the highest
significant values recorded in the first and second generations were for the Helaly and Hatour varieties, especially
in the fourth (last) cut, after which the seeds are taken for the next generation, which can be focused on in future
studies as determinants for selecting the available breeding materials from the two experiments in the third
generation. أجريت تجربتان حقليتان بمحطة التجارب والبحوث بكلية الزراعة جامعة القاهرة بالجيزة لاستكشاف تأثير ثلاث جرعات من أشعة جاما وهى 15 ،30 45 كيلو راد (التجربة الأولى) وخمسة تركيزات من أزيد الصوديوم؛( 0-1000-2000-3000-4000 جزء في المليون (التجربة الثانية) بشكل منفصل على إنتاجية وتباين بعض أصناف البرسيم المصري خلال موسمي 2020/2021 (M1) و2021/2022 (M2).
أظهرت النتائج أن المعاملة بالإشعاع بجرعة 45 كيلو راد ، في الجيل M1، أدى إلى زيادة محصول العلف الاخضر فى كل من الحشة الأولى والثالثة والرابعة ولكن بشكل غير معنوى مقارنة بمعاملة المقارنة (بدون اشعاع) أو الجرعات الأخرى في نفس الحشات. في الجيل الثاني (M2)، كان هناك انخفاض كبير في المحصول عند المعاملة بالجرعات الأعلى مقارنة بمعاملة الكنترول للمحصول الاخضر عند الحشة الأولى والرابعة، في حين أن الانخفاض فى محصول الحشة الثانية والمحصول الاخضر الكلى كان غير معنوى. أظهرت نتائج الدراسة عدم وجود فروق معنوية فى إنتاج العلف الجاف لنباتات البرسيم المعاملة بجرعات من أشعة جاما في الأجيال M1 و M2.
