K17eA系列组合选育技术研究总结

Summary of Breeding Techniques for A Series of Combinations of K17eA

e型杂交水稻是高秆隐性(eui)杂交水稻的简称。本文介绍了江西省赣州市农业科学研究所第一阶段有选择地利用现成的杂交稻亲本中的具有新质源不育系的保持系育成同型长穗颈不育系K17eA及其系列组合的情况,包括K17eA的选育经过,e型杂交水稻(K17eA系列组合)在区域试验中的产量、性状、米质和抗病性表现,K17eA系列组合的育种技术体系、亲本种子原种生产模式、繁殖制种配套技术以及高产栽培技术。

e-type hybrid rice is the shortened form of high-stalk and recessive(eui) hybrid rice.Sterile line K17eA with elongated uppermost internode and its ten hybrid combinations(e-type hybrid rice) were bred during 1999~2007 by Ganzhou Institute of Agricultural Sciences in Jiangxi Province.This article introduced the breeding process of K17eA,the yield,character,rice quality and disease resistance performance of ten e-type hybrid rice combinations in the regional tests,and the breeding technology system,parents o...
