Evaluation of half-sib progenies developed from RTM 314 in Eruca sativa for seed yield and its components

Variability, heritability and correlations were studied in 150 half-sib fam ilies generated from RTM-314 variety of taramira,in RED with two replicatio ns. The estimates of sigma(A)(2) and sigma(P)(2) for plant height, number o f secondary branches, number of siliquae per plant and number of seeds per siliquae were very low. The estimates of heritability (narrow sense) were v ery high for plant height, number of secondary branches, number of siliquae per plant and number of seeds per siliquae. The expected selection gain be tween families was lower in comparison to expected gain from within family selection. Correlation analysis has shown positive association of plant hei ght and number of siliquae per plant with seed yield per plant in the half- sib progenies. It is suggested that, based on secondary branches and number of seeds per siliquae, superior progenies may be used to reconstitute new populations for the improvement of seed yield in RTM 314.
