“…This indicated the major role of additive gene action for the expression of these traits and improvement in these traits could be made by selection in Indian mustard. The present findings are in accordance withShekhawat et al (2014),Raliya et al (2018),Gupta et al (2019),Tripathi et al (2019) andPandey et al (2020). Seed yield, being a complex quantitative trait, is https://doi.org/10.37992/2021.1202.083Patel et al,…”

Forty five genotypes of Indian mustard [Brassica juncea (L.) Czern and Coss] were evaluated for seed yield and quality traits in Randomized Block Design with four replications during the Rabi, 2019-2020. The analysis of variance revealed that the mean sum of squares due to genotypes was significant for all the eighteen characters studied indicating the presence of variability for all the traits among the genotypes under study. Low difference between genotypic and phenotypic variances revealed that the contribution of genotypic variance to total variance was more for all the traits except days to maturity and plant height. The high values of genotypic and phenotypic coefficient of variation for the number of branches per plant, seed yield per plant , myristic acid, palmitic acid and stearic acid which indicated the potential variability available for these traits. The high heritability estimates obtained in conjunction with high genetic advance were observed for the number of branches per plant, the number of siliquae per plant, seeds per siliqua, length of siliqua , 1000-seed weight , seed yield per plant , myristic acid , palmitic acid, stearic acid , linoleic acid , linolenic acid and glucosinolate suggesting the predominant role of additive gene action for their expression. Association analysis between seed yield per plant and other seventeen characters revealed significantly positive correlation of seed yield per plant with the number of siliquae per plant, seeds per siliqua, length of siliquam, myristic acid and erucic acid. Path analysis revealed positive direct effects of the number of siliquae per plant and seeds per siliqua towards seed yield per plant while myristic acid, the number of branches per plant had a positive indirect effect on seed yield per plant via the number of siliquae per plant suggesting that the selection for such traits would be more effective for improving seed yield in Indian mustard.

“…Similar findings were earlier reported byRaliya et al (2018),Chaurasiya et al (2019),Kumar et al (2019),Tripathi et al (2019),Pandey et al (2020) andSaiyad et al (2020a). The GCV and PCV do not confirm the full scope of heritable variation in genotype under study.…”

Indian mustard (Brassica juncea (L.) Czern & Coss) is the major oilseed crop of India ranking first both in acreage and production of rapeseed and mustard in Asia. Among abiotic stresses, drought condition may cause the most fatal economic losses in agriculture due to their wide range occurrence. Present investigation was undertaken with the objective to study RB 50 Ã— Kranti F2:3 population under irrigated and drought environments for phenotypic and genetic variability, broad-sense heritability, and interrelationships among agronomic and seed quality traits to select Indian mustard genotypes for drought tolerance in research area of oilseed section. The study was carried out at CCS Haryana Agricultural University, Hisar during rabi 2014-15. Higher mean values for agronomic traits were observed under irrigated than drought environment. Phenotypic correlation coefficient analysis of F2:3 populations under irrigated conditions was calculated to assess the association between various traits. Fifty three promising plants with higher seed yield as well as better physiological traits having greater drought tolerance were selected, which may be useful material for further studies and cultivar development for drought tolerance.
