本文通过对ＢＴ和ＵＰ细胞质的３个不育系与４个恢复系配制的１２个杂种，及其相应保持系杂种Ｆ２种子的加工和外观７项米质性状的表现型的比较表明，ＢＴ和ＵＰ细胞质对杂交粳稻的精米率、整精米率和垩白米率有明显的负效应，但对糙米率、糙米长、宽和长／宽比则没有影响，不育细胞质的这种负效应，具有很大的组合特异性，尤以恢复系的影响较大。胞质效应的变异占不育系杂种总变异的２４～６７％。
In this paper, BT and UP cytoplasmic three sterile lines and four restorer lines of the 12 hybrids prepared, and its corresponding maintainer hybrids F2 seed processing and appearance of seven quality traits of phenotypic comparison, BT and UP cytoplasm had a significant negative effect on milled rice rate, milled rice rate and chalkiness rice rate in hybrid japonica rice, but had no effect on brown rice rate, brown rice length, width and length / width ratio. This negative effect of sterile cytoplasm had Large portfolio specificity, especially in the greater impact of the restorer line. The cytoplasmic variation accounts for 24-67% of the total variation in CMS hybrids.
