Abstract: A study was undertaken to assess the genetic variabilityamong 125 high oleic advanced breeding lines for agronomic traits during summer 2013-14 and kharif 2014for the identification the potential lines for pod yield and its components, oil quality traits, foliar disease resistance and association pattern of these traits for the improvement of low heritable traits through indirect selection of the highly heritable traits. 68 high yielding lines were also evaluated for yield trial in larger plots during kharif 2014. The analysis of variance revealed significant variation among the high oleic advanced breeding lines, seasons and genotypes x season interaction for all the traits evaluated. PCV was higher in magnitude than the GCVin respect of all the traits studied. Heritability in broad sense and genetic advance as per cent mean were higher for pod weight/plant, pod yield, kernel yield and oil yield, reaction late leaf spot and rust. Pod yield was positively and significantly correlated with pod weight per plant, shelling per cent, 100 seed weight, kernel yield, per cent mature kernels, number of mature pods per plant and oil yield indicating that pod yield per plant could be used as preliminary criteria for selecting high yielding genotypes.Oleic acid and linoleic acid were negatively and significantly correlated and therefore selection of one would decrease the other.Most of the consistently superior high oleic lines were also significantly superior for other quality traits across the season viz., pod yield, kernel yield, oil yield and protein content. Line no. 52, 70, 81, 69 and 32 has significantly high pod yield than check, GM4-3 (3826 kg/ha); line no. 52, 81, 32 recorded for high kernel yield than check, GM4-3 (2730 kg/ha) and line no. 52, 70, 58, 69, 32 and 95were consistently superior for protein content over the check, GM4-3 (34%).
