التداخل البيئي والوراثي في بعض الطرز الوراثية من الشوفان تحت تأثير نوعيات مختلفة من مياه الري

Abstract EN

In this study, ten oat genotypes (Alguda, Anatolia, Pimula, Genzania, Hamel, Icarda short, kangaroo, Icarda tall, Mitika and Possum) were used under the impact of three irrigation water types and two agricultural seasons.

performance and genetic and environmental interaction were studied according to Eberhart and Russel and cluster analysis for days to anthesis, plant height,flag leaf area,no.effective tillers, no.grains.

panicul, 1000 grains weight and grain yield (t.he), we reached the most important results that was through obtaining statistically significant in analysis of variance table of the sources of difference in environments, genotypes and the interaction between them for all characteristics under study.

genotype (6) distinguished in no.effective tillers (141.06 tiller.m²), no.grains.panicul' (66.89 grain.panicul") and grain yield (1.48 t.he) and genotype (1) in days to anthesis (110.70 day) and no.effective tillers (136.67 tiller.m) and the interaction between fourth environment and genotype (6) for no.grains.panicul (66.67 grains,panicul¹) .in addition to this uniqueness in performance, genotype (6) proved its stability for plant height, 1000 grains weight and grain yield (t.he") .these indices are feasible with evidence that they coincided with yield and some of its components, as well as to high stability to be implemented in future after testing with other factors.

in addition to that, obtaining the state of the genetic distance between genotypes tested across environments, in particular genotype (8) with genotypes (6 and 7) and hence can be used in breeding programs, especially hybridization.
