Association of seed iron and zinc content with seed yield and other traits in sesame (Sesamum indicum L.)

Selfed progenies derived from diverse populations were evaluated in two seasons at Agricultural Experimental Farm, University of Calcutta, Baruipur, West Bengal, India to investigate the correlation of seed iron (Fe) and zinc (Zn) content with seed yield and component traits in sesame. Significant genetic variability among the progenies was observed for Fe, Zn seed yield and other component traits. Significant and positive correlation was observed between Fe and Zn. Seed yield was significantly correlated positively with plant height, capsule no/plant and 1000 seed wt. While Fe content in seed was negatively associated with capsule length. The PCA revealed that seed yield per plant had a strong relation with capsules per plant and plant height suggesting the need for more emphasis on these components for increasing the seed yield in sesame. Zinc and iron also had a strong relationship but there are no significant relationship with seed yield per plant and micronutrients.
