Identification of Heterotic Cross Combinations for Grain Yield and Head Rice Recovery in Rice (oryza Sativa L.) Hybrids
Year: 2025
Type: article
Abstract: This study aimed to assess the extent of heterotic effects over mid, better and standard parent for grain yield, head rice recovery and various other quantitative and qualitative traits.Analysis of variance indicated significant difference among the genotypes for various traits.Estimates of relative heterosis, heterobeltiosis and standard heterosis were calculated.CMS 64A × SN 2397, CMS 64A × BV 166, RMS 2A × BV 166, CMS 52A × SN 223 and CMS 64A × SN 232 recorded high standard heterosis over two checks for grain yield.For the trait, head rice recovery JMS 18A × SN 2397, CMS 52A × SN 223, JMS 18A × SN 232 and RMS 2A × SN 2397 these hybrids recorded high standard heterosis.The hybrid CMS 52A × SN 223 is heterotic hybrid for both grain yield and head rice recovery.This hybrid could be exploited commercially after critical evaluation for its superiority and stability across the locations over years.
