Abstract
One hundred accessions along with 5 check varieties of taramira (Eruca sativa Mill.) evaluated for grain yield during 2013-2014. Analysis of variance showed that accessions had significant differences for all the traits except plant height and number of primary branches per plant. The checks varieties also exhibited significant differences for all the traits except plant height and number of primary branches per plant; this indicated that check varieties had high variability among them. Wide range was observed for the character siliquae per plant, plant height, days to maturity, days to 50 percent flowering, seeds per siliqua, and seed yield per plant, seeds per siliqua and oil content. The phenotypic variance was higher than the genotypic variance for each of the character studied indicating positive effect of environment on the expression of a character. High heritability coupled with high genetic advance was observed for seed yield per plant. High heritability and moderate to low genetic advance were observed for oil content, days to 50 per cent flowering, number of secondary branches per plant and seeds per siliqua. Coefficient of variance indicated that the variability was highest for seed yield per plant followed by number of secondary branches per plant and number of primary branches per plant. The lowest variability was observed for days to maturity, oil content, seeds per siliqua, days to 50 per cent flowering, siliquae per plant, plant height and test weight.
