گزینش تجزیه همبستگی عملکرد دانه در لاین‌های هاپلوئید جو (Hordeum vulgare L.)

In order to study the relation among agronomic and morphologic traits, 45 barley genotypes have been experimented in the form of a complete randomly blocks plan with  repeat modes in  normal watering and dehydration stress in Miandoab Agricultural Research Station in. The results of variance analysis in two watering states of normal and dehydrated one have shown that there is significant differences among all studied features except plant height and the length of peduncle. In the state of normal watering, there is much correlation among the function of seed and  grain weight with the chaff. Also there is a strong relation between the index of harvest and the weight of  grain weight. The most correlation efficiency of the seed function was found in the dehydrated stressed watering with chaff function and harvest index. Also in such a state, there is a strong correlation efficiency of the weight of  grain weight and harvest index. The yield path analysis showed that in desirable and normal watering state, the function of chaff and the weight of  grain weight, and in dehydrated watering state, chaff function has got the most direct and positive effect on the function of seeds, although the indirect effects in both cases were not significant.
