Genotypic and Phenotypic Association among Seed Quality Traits in Indian Mustard (Brassica juncea L. Czern & Coss.)

Résumé

The present investigation was conducted during 2024 in the Department of Seed Science and Technology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.), India, using thirty varieties of Indian mustard (Brassica juncea L. Czern & Coss.) to evaluate seed quality parameters. Eleven seed quality traits were assessed, and correlation coefficients were computed at both phenotypic and genotypic levels. The genotypic correlations generally exhibited similar directions but were of greater magnitude than the phenotypic ones. Vigour index showed a highly significant positive correlation with seedling length (0.940) and root length (0.893), but a significant negative correlation with speed of germination (-0.361). Seedling length also displayed a highly significant and positive correlation with root length (0.893), while both traits were negatively correlated with speed of germination at the field level. Shoot length had a significant positive correlation with first count (0.379), and root length correlated significantly with speed of germination (0.387). Speed of germination was highly significantly correlated with germination percentage (0.485, 0.500), and germination percentage had a significant positive relationship with field emergence (0.382). A significant negative correlation was observed between first count and 1000-seed weight (-0.415). The findings suggest that traits such as seedling length, root length, and speed of germination can serve as reliable indicators for seed vigour and quality improvement in Indian mustard breeding programs.
