Genetic Analysis of CMS Based Rabi Sorghum (Sorghum Bicolor [L.] Moench) Single Cross Hybrids For Grain Yield and Yield Components

The present investigation included twenty six CMS based rabi sorghum single cross hybrids evaluated at Foragen Seeds R&D farm located at Hyderabad, during rabi 2024. All 26 hybrids along with two commercial checks (repeated once) i.e. HT-3201 and HT-3206 for comparison. A trial of 30 hybrids was planted in randomized block design with two replications. Each hybrid was planted as 2 rows of 2m length and 30 cm spacing, all required recommended dose of fertilizers and agronomic practices were followed to see the full genetic potential of hybrids. Data was collected for five morphological traits viz., days to 50% flowering, plant height (cm), panicle length (cm), grain yield (kg ha-1) and Green fodder yield (tons ha-1). The ANOVA revealed that the hybrids were found significantly different for all the morphological traits under study. Based on the mean performance and cluster analysis, one hybrid i.e FGSH-7 was out yielded over check HT-3201 whereas, FGSH-25 was at par with check HT-3201 and none of the hybrids were found superior over check HT-3206. This means that hybrid FGSH-7 can be promoted for further testing in multiple locations. However, cluster I and VI were highest yielding clusters. The parents involved in the hybrids belongs to these clusters can be explored further for line development or a hybrid development program, also can be exploited for broadening of genetic base of the parents.
