威优90是湘潭师范学院生物系于1985年用V20A与早熟恢复系测90配制而成。测90是1984年在IR84123中发现的早熟突变单株,经多代选择和测交筛选培育而成。 一、区试及生产试验的产量表现 1986年该组合引入广西桂林地区进行观察鉴定,1987年参加新组合比产试验,结果表明:该组合的产量
Weiyou 90 is the Department of Biology, Xiangtan Normal University in 1985 with V20A early detection and recovery of 90 prepared from. Test 90 is a early-maturing mutant found in IR84123 in 1984, which was selected by multiple generations and cross-hatched. First, the regional test and production test yield performance 1986 introduction of the combination of the combination of Guilin, Guangxi region for observation and identification in 1987 to participate in the new combination of specific production test results show that: the combination of yield
