摘　　要：糯稻 8 9 1是通过腋芽露地越冬翌年可再生的新材料。研究表明 ,该材料抗寒力强 ,越冬后再生稻产量与正季相当 ,达 6 .2 91t/hm2 。a glutinous rice, is a new germplasm resource with the overwintering ratooning characteristic. The results showed that it was not only highly tolerant to coldness, but performed well in other agronomic characters with its overwintered ratoon crop yielding 6.291 t/hm 2, only a little lower than that of its main crop (6.386 t/hm 2). Therefore, it is a rare and precious germplasm in rice.
