甜椒雄性不育系AB91的遗传特性及杂优利用研究

甜椒雄性不育系AB91 ,是河北省农林科学院经济作物研究所以田间发现的甜椒雄性不育株为不育源 ,经十几年选育而育成的甜椒雄性不育两用系 ,是一个雄性不育性与优良农艺性状、抗病性、高配合力高度统一的不育系。其不育性由一对隐性核基因控制 ,遗传简单、不育性稳定 ,不育花与可育花易于区别 ,恢复源广泛、配合力高 ,可较快地培育出不同类型的优良一代杂种。利用AB91 已选育出早、中、晚熟配套的系列甜椒杂交种 ,解决了我国甜椒一代杂种种子生产人工去雄的难题。利用AB91 生产一代杂种 ,简化了杂交制种程序 ,大大降低了杂交制种难度和成本 ,可保证杂种种子纯度。AB91 的育成及利用具有重大的学术价值和实用价值。

Breeding and Application of Male Sterile Lines in Sweet Pepper

The male sterile line AB 91 was developed by using a male sterile plant of sweet pepper discovered in field.The line AB 91was selected by means of cross,self-cross,test cross and successive backcross.It has stable sterility with fine horticultural characters,good tolerance to diseases and high combining ability.A series of F 1 hybrid varieties of sweet pepper were released by crossing the genic male sterile line AB 91 with inbred lines.The results showed that,The male sterile line is governed by one pair of recessive genes.The sterility is stable and is transselected easily.Its restorer is widespread.It has a higher wide utilization value.
