摘要
用60 Coγ射线 35 0Gy分别照射杂交稻保持系 (B系 )和恢复系 (R系 )干种子 ,M2 获得相应的糯性基因wx突变体 ,并育成糯不育系wxA和糯恢复系wxR ,组配出杂交糯稻新组合。特优 63糯与特优 63具有相似的生育期、农艺性状、产量水平和抗性。
Dried seeds of maintainer lines Longtepu B and restorer lines Minghui 63 were treated with 60Co γ-ray at the dose of 350 Gy, the waxy mutants of them were obtained in their M_2 brown rice population respectively, then waxy CMS lines, restorer lines and hybrid rice of Teyou63 nuo were developed.Teyou63 and Teyou63 nuo have the similar growth duration,agronomic traits,yield potential,disease resistance,and high yield in seed production.=
