Evaluation of genetic variability of faba bean (vicia faba l. )‎ genotypes under different environments

الملخص EN

The development of high yielding cultivars is a primary objective in most faba bean breeding program.

This study is an attempte to evaluate sixty faba bean genotypes under different environment; Sids Research Station in Middle Egypt and Nubaria Research Station in North Egypt, during winter growing seasons 2014/2015 and 2015/2016.

The experimental design was an alpha lattice with two replications.

The combined analysis of variance over years were significant for most trait.

The results for plant height showed that G2 and G50 had the tallest genotypes at Nubaria and Sids locations, respectively.

The G42 recorded the highest values for number of pod, seeds and seed weight.

plant-1 at Sids location, whereas, G18 genotype recoded the highest number of pods.

Plant -1 at Nubaria location.

G49 and G40 recorded the heaviest 100 seed weight at Sids location, while the genotype G51 had the heaviest value at Nubaria location.

Regarding seed yield (ardab.

Fad-1), the genotypes G27and G45 gave the highest values at Sids and Nubaria locations, respectively.

The cluster analysis classified the tested genotypes in both locations to four main different groups, the first group had the highest seed yielding (ardab.

fad-1), plant height and seed weight.

Plant -1, followed by the third group cluster in the location Sids.
