本文通过对籼粳稻亚种间远缘杂交后代品系单位面积穗数、穗实粒数 ,千粒重与产量的研究分析表明 :要获得高产 ,在稳定每单位面积穗数的基础上 ,在选育和栽培过程中 ,注意选育千粒重高、穗实粒数高的后代是取得成功的关键
In this study, we analyzed the number of spikes, spikelets, 1000-grain weight and yield per unit area of cross between distant crosses between indica and japonica rice showed that in order to obtain high yield, on the basis of stable spikes per unit area, During the cultivation process, pay attention to the key to success in breeding offspring with 1000-grain weight and high spike grain number
