几个杂交粳稻恢复系配合力分析及其利用价值评价
Combining abilities and use values of several hybrid keng rice restorers
摘要
Abstract
Six different-type hybrid keng rice restorers and 6 BT-type keng rice sterile lines were used as parents,and their F1 yields and relative characters' combining abilities were analyzed by using incomplete diallel cross design (NC Ⅱ). The results showed that the descending order of general combining ability(GCA) for the restorers' grain yields was 'Fan 18'>'Fan 16'>'Fan 15'>'Shenhui C9'>'Shenhui 254'>'206'; and considering the GCAs of other characters,'Fan 15' and 'Fan 16' were better male parents. The yield and its relative characters were affected more by the restorers than by the sterile lines,so selection of restorers was of key importance though the sterile lines' effects and both parents' interaction could not be overlooked. The restorers of indica-japonica cross had good fertility restoration ability,and their combinations had outstanding competitive edge in yield and good use value.关键词
