雄性不育细胞质对玉米自交系产量性状的影响

Influence of sterile cytoplasms on yield characters of inbred lines in maize

以3组同核异质系为材料,研究不同玉米雄性不育细胞质对自交系产量性状的影响。结果表明:与正常细胞质 (N)相比,3种不育细胞质(S、C、Y1-1)对自交系产量都有显著提高;同时3种不育细胞质对自交系的其他产量性状也分别产生了显著的或正或负的影响。

The influence of sterile cytoplasm on yield characters of inbred lines with three sets of isoplasmic allounclear male-sterile lines in maize was studied. The results were as follows： comparing with normal cytoplasm, the yield of male-sterile lines with 3 types male-sterile cytoplasms were raised significantly. The other yield characters of inbred lines were also influenced by 3 types sterile cytoplasms （S, C, Y1-1）. The influence degree was different with types of sterile cytoplasm on yield characters.
