| Abstract: | Lantian 20 was a new winter wheat cultivar bred by crossing with the parental combination of Cappelle Desprez/Lantian 10.Female parent carried Yr 16 which was sustainable to stripe rust.the average yield of Lantian 20 was 5 686.5 kg/hm2 and 15.61% higher than of the check Zhongliang 22 in winter wheat regional test which was conducted during the period 2005-2006 in the high mountainous area of Tianshui city and Longnan district.Lantian 20 had the characteristics of resistance to stripe rust and powdery mildew.By inoculating identification of stripe rust in Institute of Plant Protection of Gansu Academy of Agricultural Science,the result showed that Lantian 20 was immune to mixture race at the seedling stage and also immune to CY 31,CY32,Shui 4,Shui 7,Shui 14 at the adult stage,except that it was moderate susceptibility to CY29.In addition,the result also indicated that seed crude protein and lysine were respectively 15.05% and 0.41%.Lantian 20 was suitable for growing in the high mountainous area and in semi-mountainous area of Tianshui city and Longnan city. |
