摘要
CA为新育成的籼型新质源不育系,具有IR28 的胞质,花粉不育度和不育株率均为100% ,农艺性状优良,遗传性状稳定,开花习性好,配合力强,杂种F1 代米质优、产量优势强。所配组合CA/CDR22、CA/130、CA/多系1 号、CA/绵恢2040 等在省、市区试中比对照汕优63 增产5% 以上,其中C优22 已于1999 年5 月通过四川省品种审定。
CA is a new indica CMS line with the cytoplasm of IR28 which is developed by the Mianyang College of Economy & Technology, Sichuan. Its pollen sterility and percentage of sterile plants are both 100%. It has the characteristics of good plant type, fine agronomic and genetically stable characters, good combining ability and flowering habits. Its F 1 hybrids showed strong yield heterosis and good grain quality. The grain yield of its hybrids was 5% higher than that of check Shanyou 63 in the regional trials. C You 22 (CA/CDR22) was certified by the Crop Appraisal Committee of Sichuan Province in 1999.
