Type: article
Abstract: The current study was conducted at the Botanical Garden, Department of Plant Breeding and Genetics, SAU, Tandojam during the Kharif season 2023. The experiment was laid out in a randomized complete block design with three replications. The ten genotypes Shandar, NIA Mehran, Sarshar, Shua-92, Shabab, NIA-19/A, Shandar-100-1, Shandar-200-1, Shandar-200-2, and NIA-Mehran-100-1 were evaluated for these traits i.e. days to heading, days to flowering, plant height, tillers hill-1, panicle length, fertility %, no. of florets panicle-1, grain yield hill-1. The ANOVA revealed that all the traits were significant and showed great variation among the rice genotypes except fertility%. The relationship of days to heading with DTF (0.987**), TPH (0.564**), and GYPH (0.363*) was positive and significant. The relationship of days to flowering with TPH (0.630**), and GYPH (0.455*) was positive and significant. The association of tillers hill-1 with PL (-0.513**) was negative but significant. While the relationship with FPP (-0.289NS) and FPCNT (-0.090NS) was negative and non-significant. However, its relationship with GYPH (0.704**) was positive and highly significant. All the traits showed high heritability showing minimal environmental effect, however, panicle length and fertility% showed medium heritability showing some environmental effect on them.
