Abstract
Using 3 sterile lines and 12 restorer of glutinous sorghum as experimental materials, 36 hybrid combinations (3×12 NC II) were designed to analyze the combining ability and heritability of six main agronomic traits, including plant height, panicle length, growth period, 1 000-grain weight, per panicle grains and per panicle grain weight. The results showed that except per panicle grain number all other five agronomic traits have remarkable or extremely remarkable general combining ability and specific combining ability. Six agronomic traits were found to be control by additive genetic effect. Most of these agronomic traits are more easily influenced by restorers than sterile lines, suggesting that more attention should be paid to select restores in hybrid glutinous sorghum breeding. The narrow-sense heritability of these agronomic traits were in order growth period > plant height > per panicle grain weight > panicle length > 1 000-grain weight > per panicle grains.
