Abstract

The inheritance of the leaf pubescence character of a Chinese local wheat cultivar 'Hon-mang-mai' was investigated by monosomic and telosomic analyses. Leaf pubescence was evaluated by observation of the adaxial side of the penultimate leaf of adult plants. F1 hybrids of 'Hong-mang-mai' with a non-pubescent cultivar 'Chinese Spring' had leaf pubescence, but its density was about a half of that of 'Hong-mang-mai'. In the F2 generation, the segregation ratio of pubescent to non-pubescent plants fitted a ratio of 3: 1, suggesting that leaf pubescence was controlled by one dominant gene. Monosomic analysis revealed that the gene for pubescence is located on chromosome 7B. Telosomic analysis showed that the gene is located on the short arm of chromosome 7B with a distance of 14.3% from the centromere. This gene is not allelic with the previously reported hairy leaf gene Hl on chromosome 4B, and therefore, is designated Hl2, hairy leaf 2.
