【Abstract】 Genetics of growth duration or heading dates of photoperiod sensitive rice varieties, photoperiod insensitive varieties, hybrid rice, indica/japonica subspecific hybrids and induced earliness mutants, and mapping of major genes and QTLs for heading dates, are summarized. Problems in research of major genes, mapping of QTLs for heading dates, application of dominant earliness genes in rice breeding, and their countermeasures, are discussed.更多还原
