Abstract:

Fifty-eight sunflower inbreds were evaluated for seventeen morphological parameters during spring 2019 and 2020 to understand the relationships among different traits for facilitating the indirect selection of superior confectionery sunflower inbreds. For confectionery inbreds, seed length is an important trait for making selections since seed length exhibited a negative correlation with seed volume weight which is highly correlated with oil content. Thus inbreds having higher seed length had lower oil content which is a desirable trait for confectionery sunflowers. The investigation also helped in the identification of sunflower inbred EC734798 as superior for confectionery purposes based on principal component analysis and EC734792, EC734806, EC734808, EC734831, EC734866, EC734870 and EC734790 were identified as superior inbreds based on cluster analysis. Furthermore, inbreds EC734810, EC734816I, EC734817II, EC734837, and EC734867 can be utilized for improving seed length parameters among confectionery sunflowers.
