激光诱变选育洋葱新品种

Breeding of the New Onion Variety by Laser Mutagenesis and Culture Techniques

采用CO2和He-Ne两种激光的三种剂量,分别辐照两个洋葱品种的湿种子,从激光辐照洋葱的变异后代中,经8年多的选育,培育出两个红皮洋葱新品种,2004年经四川省品种委员会审定通过,定名为西葱1号(川审蔬2004020)和西葱2号(川审蔬2004021)。新品种表现出早熟、耐贮存、株形紧凑、早期抽薹率低、产量高、抗病性好等优良性状,符合生产和市场要求,可作为目前生产上种植推广品种。

The new onion variety ＂Xicong 1＂ and ＂ Xicong 2~＇ were bred by laser mutagenesis （ CO2, He-Ne） ,laboratory identification and productive test in Sichuan Province showed that ＂Xicong 1 ＂＇ and ＂Xicong 2＂ were not only premature, stability in storage, compact shape, the low rate of premature bolting, but also of high quality, good disease resistance, meeting the requirements of production and market. It can be used as extension varieties in the production.
