高柱头外露率中粳不育系春江99A的选育和利用
Breeding and Utilization of Late Medium Japonica CMS Line Chunjiang 99A with High Stigma Exsertion Rate
摘要
Abstract
Chunjiang 99A is a late medium Japonica CMS line, developed through crossing Chunjiang 99B(Chunjiang 19B×Chunjiang 099) to Chunjiang 16A and successively backcrossing with Chunjiang 99B as recurrent parent, It was registered and released by Zhe-jiang Provincial Crop Variety Appraisal Committee in 2014. Its percentage of sterile plants was 100%, and its pollen sterility was 99.99%. It had the characteristics of high stigma exsertion rate, early flowering, high outcrossing rate, good plant type, pale green leaf and good combining ability. Its F1 hybrids especially for Japonica-Indica cross hybrids showed dominant heterosis, light leaf color, strong lodging resistance, short whole growing period and good color change in mature stage.关键词
