Genetic architecture of yield and its contributing characters in postrainy-season sorghum

摘要

Knowledge of the genetic behavior of various characters is important in the selection of superior parents for hybridization is a successful breeding program. The present study was undertaken to assess the combining ability of different genotypes forseed yield and its components in postrainy-season sorghum [Sorghum bicolor (L.) Moench] using line X tester analysis with the objectives of studying gene action governing yield and its contributing characters, and of identifying good parents from a set of established varieties, local germplasm, and derived lines.
