对215份来自墨西哥、印度、巴基斯坦等22个国家的春小麦品种进行了产量、株高、生育期及抗性的鉴定。结果表明,品种间产量性状差异很大,尤其是产量和千粒重变幅更大。产量高于扬麦5号10%的有42个品种,千粒重超过38g的有15个品种,容重高于760g/L的有89个品种。平均株高为93.7cm,其中90~100cm的为133个品种,抽穗灌浆期大多短于扬麦5号。对白粉病有较好抗性,但大多数感染赤霉病。经综合鉴定评选,CULIACAN89、TUI、UP262三个品种利用价值较大。同时,对国际春小麦品种利用现状及前景进行了初步探讨。
The yield, plant height, growth period and resistance of 215 spring wheat cultivars from 22 countries such as Mexico, India and Pakistan were identified. The results showed that the yield traits varied greatly among varieties, especially the yield and 1000-grain weight fluctuated more. There were 42 varieties with 10% higher yield than Yangmai 5, 15 varieties with more than 38g of grain weight and 89 varieties with bulk density higher than 760g / L. The average plant height was 93.7 cm, of which 133 varieties were from 90 cm to 100 cm. The heading stage was mostly shorter than that of Yangmai 5. Powdery mildew has better resistance, but most are infected with scab. The comprehensive appraisal, CULIACAN89, TUI, UP262 three varieties of greater value. At the same time, the status quo and prospects of international spring wheat varieties were discussed.
