母本有效穗是构成不育系繁殖产量三大因素之一,而有效穗在很大程度上是由母本栽插苗数决定的。实践表明,在一定范围内,母本有效穗随着母本栽插苗数增加而增加,穗总粒数随着基本苗的增加 The female parent panicle is one of the three major factors that make up the CMS. The effective panicle is largely determined by the number of female parent plants. Practice shows that within a certain range, the female parent effective spike with the number of female plant transplanting increased, the total spikelets with the basic seedlings increased
