التحليل الوراثي لمتوسطات الأجيال ذاتية الإخصاب لتهجينين في الحنطة الخشنة

الملخص EN

Six self-fertilized generations (P1, P2, F2, F3, B1S and B2S) of two crosses in durum wheat (Triticum durum Desf.), the first cross between Azeghar-1 and Um-Rabie-5 and the second cross between Leeds and Waha, were used to study gene action for the traits, heading time, flag leaf venation, plant height, peduncle length, number of spikes, spike length, grain yield, 100 grains weight and number of grains per spike.

Two models were used in analyzing the components of the generation means, three –parameter model and sixparameter model.

The results from the generation mean analysis showed that the threeparameter model was adequate for the inheritance of spike length and weight of 100 grains in the both crosses and number of spikes per plant in the second cross but there were additive, dominance and epistatic effects on the other characters in the both crosses.
