为进一步优化小麦品种结构,提高小麦产量和品质,确保粮食和食品安全,采用品种同异比较(理想值法)分析方法,对14个小麦新品种(系)的15个性状进行了综合分析,从中筛选适宜宝鸡生态条件下种植的小麦新品种(系)。结果表明,‘西农167’综合同一度最大(0.9622),说明该品种在14个参试品种(系)中综合性状表现最好,15个性状中有96.22%的性状达到了育种目标要求,其次是‘漯6073’(0.9104),产量较高,抗倒伏和综合抗病性强;再次是‘新麦0401’(0.9021)、‘长河25’(0.8954),均表现为抗倒、抗病,产量三因素协调;对照‘周麦18’(0.8713),试验中产量中等,但该品种在当地多年表现综合性状较好,高产、稳产,因此,仍不失为一个优良品种。因此,在14个参试品种(系)中,‘西农167’、‘漯6073’、‘新麦0401’、‘长河25’、‘周麦18’等5个品种(系)综合性状表现优异,适宜在宝鸡市川塬灌区生态条件下示范种植。
In order to further optimize the structure of wheat varieties, increase wheat yield and quality, and ensure food and food safety, 15 traits of 14 new wheat varieties (lines) were comprehensively analyzed by means of the same value comparison (ideal value) The new wheat varieties (lines) planted under the ecological conditions in Baoji were selected. The results showed that the comprehensive identity of ’Westong 167’ was the highest (0.9622), which indicated that the cultivars had the best comprehensive characters among the 14 tested cultivars (lines), 96.22% of the 15 traits met the breeding goal, Followed by ’Luo 6073’ (0.9104), with higher yield and lodging resistance and comprehensive disease resistance; again, ’Xinmai 0401’ (0.9021) and ’Changhe 25’ (0.8954) all showed resistance to disease and disease resistance , And the yield was coordinated by three factors. Compared with Zhoumai 18 ’(0.8713), the yield was moderate in the experiment. However, the variety showed good comprehensive performance for many years in the local area, with high yield and stable yield. Therefore, it was still an excellent variety. Therefore, among the 14 tested cultivars (lines), the comprehensive traits of 5 varieties (lines) including ’Xinong 167’, ’Luo 6073’, ’Xinmai 0401’, ’Changhe 25’ and ’Zhoumai 18’ Excellent, suitable for demonstration in Baoji Sichuan Sichuan Irrigation District ecological conditions.
