- Abstract
Using the parants of two-line hybrid indiea rice varieties ‘yunliangyoul44’ as the research object, fertility transformation tide of female parents 2301S and the maintraits and reproductive process of parents were studied at different soving time in different ecological conditions in Shuifu county of Yunnan province. Through the analysis of the difference of parents main properties, such as duration from seeding to heading, main stem leaf number, fertility rate ( setting) in different ecological conditions, the ‘yunliangyoul44’ parents regression equation of the main characters was set up, which provided technical guidance of ‘yunliangyoul44’ under different ecological conditions in the local terraces breeding and also provided technical reference of two-line hybrid rice in high purity and high yield breeding in low latitude plateau area.
