摘要 冬小麦新品种兰天23号是通过有性杂交系统选育而成,其亲本组合为SXAF 4-7/87-121。2004-2005年度在天水市川区组区试中,平均折合产量7 578.0 kg/hm2,较对照品种兰天6号增产65.20%,居11个参试品种(系)的第2位;2005-2006年度在甘肃省陇南片川区组区试中,平均折合产量7 500.0 kg/hm2,较对照品种兰天13号增产10.30%,居10个参试品种(系)的第1位。经接种鉴定,苗期对条锈菌混合菌中感,成株期对条中29号、条中31号、条中32号及致病类型水4、水7和水14免疫。籽粒含粗蛋白13.64%、赖氨酸0.42%。适于在天水市和陇南市的川区种植。 Lantian 23 was a new winter wheat cultivar bred systematically by crossing with the parental combination of SXAF4-7/87-121. the average yield of Lantian 23 is 7 578.0 kg/hm^2 and 65.20% higher than of the check Lantian 6 in winter wheat regional test which was conducted in the valley area of Tianshui city in 2005, which was the second within 11 cultivars. The average yield was 7 500. 0 kg/hm^2 and 10. 30% higher than the check Lantian 13 in the valley area of Longnan district in 2006, which was the first within 10 cultivars. By inoculating identification, the result showed that Lantian 23 was moderate susceptibility to mixture race at the seedling stage and immune completely to CY 29, CY 31, CY 32,Shui 4,Shui 7,Shui 14 at the adult stage. In addition, the result also indicated that seed crude protein and lysine were respectively 13.64% and 0. 42%.
