ABSTRACT
The present investigation was undertaken to select the genetic variability, correlation and path analysis among 51 released linseed varieties was studied using multivariate analysis for eleven quantitative traits in rabi 2010 at College of Agriculture, Nagpur. The analysis of variance revealed significant variation among released varieties for days to 50 per cent flowering, days to maturity, plant height, 1000 seed weight, fatty acid profile (Omega-6 and Omega-3) and SDG indicating the presence of genetic variability. The results obtained in the present investigation clearly indicated that improvements of seed yield are simultaneously possible through indirect selection for number of capsules per plant which is highly correlated with seed yield. The correlation studies indicated that selection for increased 1000 seed weight will be indirectly helpful for increase in Omega-3 fatty acid. Similarly, selection for high Omega-3 fatty acid will indirectly result in selection of line with high SDG. Omega-6 fatty acid will indirectly result in selection of with high Omega-3 fatty acid. The path analysis indicates that capsules per plant are the most important traits in influencing seed yield. Thus, selection for high number of capsules per plant is pre-requisite for attaining higher seed yield in linseed.
