[Genetic study of plant height of tall plant mutant Mh-1 in rice (Oryza sativa L.)].
Mh-1 is a tall plant mutant induced by irradiation from semi-dwarfed variety Guichao 2. The genetic analyses were carried out through the F1, F2, F3 progenies and test-crossed F1 on Mh-1 crossed with materials with sd-1 gene, non-allelic gene to sd-1 and common tall plant. The results indicate that the induced tall plant trait of Mh-1 is controlled by a recessive inhibiting gene, named tentatively i-sd-1(t), that can regulate the expression of sd-1 gene but not of non-allelic gene to sd-1. The valuation of i-sd-1(t) in hybrid rice breeding was discussed.
