Abstract
The study aimed to evaluating the correlation relationship between seed yield and its some related characters for mutants resulting from the treated chickpea seeds variety Gab 5, which treated by Different doses of gamma ray (15- 20 and 25) KR.
The seeds planted during the season 2017/2018 in lines without an experimental design at the Agricutural Scientific Research Center in Lattakia, to obtain mutants which may compose a base of new varieties in increasing and improving chickpea production activity in future. The results showed in the first mutant generation that seed yield per plant had the highest positive and significant correlation with number of pods per plant (r = 0.984 ) at the dose 20 KR and (r = 0.982) at the dose of 15 KR and (r = 0.977) at the dose of 25 KR, while the second strongest correlation for seed weight was with the number of seeds per the plant (r = 0.984), (r = 0.978), and (r = 0.966) at doses 20 KR, 25 KR and 15 KR, respectively. Whereas, the third strongest correlation for the seed weight was with the plant height (r = 0.668), (r = 0.650) and (r = 0.545) at doses 25 KR, 20 KR and 15 KR, respectively. Therefore, these traits could be included as selection criteria for Improvement seed yield in chickpea.
