| Abstract: | In this paper, with aid of graph recognition and variance analysis, an appraisal was made on fertility category of new lines of sterile rice with which united ecological experiments had been carried out on three sites located in Sanya, Wuchang and Guiyang respectively. Fertility stability of these lines was further analyzed, which may provide important foundation for judging the practical value of newly bred lines and their suitable planting regions. |
