1997～ 1 998连续两年对两种胞质 ( Y - 、 N)掖单 1 3主要农艺性状进行了比较试验。结果表明 :1 Y - 型不育细胞质对掖单 1 3 1 2种主要农艺性状的影响多表现为遗传正效应 ,其中单株产量增加了 8.61 %,达极显著水平。2含有Y - 型不育细胞质的掖单 1 3与正常胞质的掖单 1 3生育期相近
The main agronomic traits of the two cytoplasmic (Y -, N) Yedan 1 3 were tested for two consecutive years from 1997 to 1988. The results showed that the effects of 1 Y - type cytoplasm on the main agronomic traits of Yiyou 1 3 1 were more than genetic positive ones. The yield per plant increased 8.61%, reaching the extremely significant level. 2 Yedan 1 3 containing Y - type sterile cytoplasm had similar growth period to that of Yedan 1 3 of normal cytoplasm
