Abstract:
Thirty maize inbred lines were evaluated during Kharif, 2020 at Sri Venkateswara Agricultural College, Tirupati, to determine the nature and magnitude of genetic variability for 16 yield and yield attributes. The analysis of variance revealed significant differences among inbred lines for all the characters under study indicating the presence of considerable amount of genetic variability in the material. High GCV and PCV were recorded for kernel yield plant-1 followed by protein content, specific leaf area, ear length, plant height and number of kernels row-1 indicating the ample amount of variation among the inbred lines and thus, simple selection would be effective for the further improvement of these characters. The traits viz., kernel yield plant-1 followed by protein content, ear length, plant height, tassel length, harvest index, number of kernels row-1 and specific leaf area exhibited high heritability coupled with high genetic advance as per cent of mean indicating the preponderance of additive gene action and selection may be effective for these traits.
