梗稻广亲和种质02428h中倒一节间伸长的性状由一对隐性基因(h基因)所控制,本实验证明了将h基因导入保持系与雄性不育系中均能得到遗传表达,促进倒一节的伸长。h基因与可育胞质及野败不育胞质作用后分别使穗伸出度达15cm,1.2cm,而相应珍汕97B及珍汕97A穗伸出度仅分别为1.7cm,-9.8cm。即h基因使穗伸出度分别提高8.8倍及1.2倍。因此,利用h基因有可能充分消除雄性不育系的包颈现象。The character of greatly elongated uppermost internode of wide compatible japonica rice 02428h iscontrolled by a recessive gene(b gene). The study shows that h gene could get genetic expression in maintaince andmale-sterile line(MS-line) and make the uppermost internode elonged. H gene interacts with the fertile and wild abortive male sterile cytoplasm make panicie neck exsert to 15cm and 1.2cm, while panicle neck exsertions of parents zhenshan 97B and A were 1.7cm and -9.8cm. So, h gene makes panicle necks exsert 8.8 and 1.2 times repectively. Its is possible to introduce h gene into male-sterile line so as to eliminate panicle endosure. |
