摘要： Thermosensitive genic male sterility (TGMS) in rice is a useful trait for exploitation of heterosis, especially of inter-subspecific kind using two-line system. Three pairs of independent recessive (tins) genes with additive effects were involved in TGMS expression in UPRI 95-140 TGMS. Expression of the trait in F-2 generation involving 44 different genetic backgrounds indicated monogenic (3F:1S), digenic (15:1S) and trigenic (63F:1S) inheritance with frequencies of 18.2, 52.3 and 29.5% respectively. No single pair of genes was capable of causing complete male sterility. Two pairs of major tms genes in UPRI 95-140TGMS, non-allelic to any of the known tms genes, were located on chromosomes 3 and 7, and tentatively designated as tms6(t)-and tms7(t) respectively.
