tailieunhanh - Correlation and path coefficient analysis for yield contributing traits and grain zinc concentration in biofortified inbred lines of maize (Zea mays L.)

The present investigation was undertaken with the objective to study correlation and path coefficient analysis for yield contributing traits and grain zinc concentration in 30 biofortified inbred lines of maize (Zea mays L.). Trials were conducted during kharif 2017 at Agricultural Research farm, Institute of Agricultural Sciences, BHU in Randomized Block Design with three replications. Each entry was planted in row-to-row and plant-to-plant spacing of 60 cm x 20 cm. All the recommended packages of practices were followed to raise a good crop. In general, genotypic correlation coefficients were higher than the phenotypic correlation coefficients, indicating that there is strong inherent association between the various traits investigated in this work. Tassel length, ear height and plant height was positively and significantly associated with grain yield per plant and grain zinc concentration which indicates the importance of these traits in selection for high yielding inbred lines. Path analysis studies showed direct positive effect of cob diameter, tassel length, ear height, days to 50% silking, 100 seed weight and plant height on grain yield per plant. Hence, these traits can be considered as important attributes for suitable selection criteria for both direct and indirect selection. | Correlation and path coefficient analysis for yield contributing traits and grain zinc concentration in biofortified inbred lines of maize (Zea mays L.)
