Abstract

Variability, heritability and phenotypic correlation coefficient in the Local variety population of Nigella saliva were estimated. The results reflected relatively moderate values of variability for most of the studied characters. Heritability estimates of number of main branches per plant and capsules number per plant appeared to have high values, whereas those of earliness, plant height, herb weight per plant, seed weight per plant, crude and essential oil percentage were comparatively moderate. Estimates of phenotypic correlation coefficient showed that earli‌ness was positively correlated with each of number of main brainless, herb weight, seed weight, capsules number and crude oil. There was a positive correlation between all previous characters. Other phenotypic correlation between the possible pairs of the characters were estimated.
