优质杂交水稻岳优9113抗寒性研究

摘要

通过分期播种试验,研究了不同播种期岳优9113、岳优63、金优207三个品种各性状的变化,结果表明：岳优9113经济性状及产量性状的变化幅度与抗寒对照品种金优207相似;与对照品种岳优63相比,各性状变异系数较小,结实率较高。说明岳优9113是一个抗寒性强的杂交水稻组合,生产适应性较强。%The characters change of Yueyou9113,Yueyou63,Jinyou207 were analysed at different sowing date.The results show that the changes of economic characters and yield characters of Yueyou9113 were similar with Jinyou207,but compared with Yueyou63,coefficient of variation of each trait was smaller and relatively seed setting rate was higher.So it indication that Yueyou9113 is a hybrid rice combination of strong cold resistance and wider adaptability in the production.
