The present investigation was carried out with a set of ten genotypes of linseed and their fourty five F1S synthesized through diallel design excluding reciprocals. These were grown in Randomized Block Design during rabi season of 2019-2020 at farm of AICRP on linseed and mustard, College of Agriculture, Nagpur and studied for eight quantitative characters. The observations were recorded on i.e. plant height (cm), number of branches plant-1, number of capsule plant-1, budfly infestation (%), days to 50% flowering (on plot basis), days to maturity (on plot basis), seed yield plant-1 (g) and 1000 seed weight (g). Analysis of variance showed highly significant differences among the genotypes for all the characters studied. Four parents viz., NL 115, Neelum, Tiara and PKV NL 260 possesed positive significant gca effects and NL 115 and PKV NL 260 gaves high mean performance and were found good general combiners for seed yield plant-1, number of capsule plant-1 and 1000 seed weight and the six parents namely Neela, EC 99001, NL 367, NL 142, Padmini and NL 165 possesed negative GCA effects and were found good general combiners for bufly resistance. Hence, PKV NL 260 on crossing with EC 99001 and Neela and NL 115 on crossing with EC 99001 and Neela can be used in hybridization programme to get better transgressive segregants for yield and budfly resistance. Among the 45 crosses studied, the crosses NL 165 × Neelum, NL 142 × Padmini, EC 99001 × PKV NL 260 and NL 367 × Tiara were found most promising as they possessed high mean performance for most the yield and yield contributing character along with negative non significant SCA effect for seed yield plant-1, number of capsule plant-1 and 1000 seed weight. The parents involved in these crosses also possessed high mean performance for yield and yield contributing characters and desirable GCA effects for yield and yield contributing characters in both the parents and thus can be used in varietal development.
