中文摘要:
      为筛选抗倒伏能力强的高产裸燕麦品种,对16个裸燕麦品种的抗倒伏能力和产量进行比较,利用主成分分析和通径分析对与抗倒伏相关的7个性状进行分析。结果表明,裸燕麦品种间地上部生物量构成、主要农艺性状、茎秆基部第二节间形态及倒伏指数、产量及其构成因素均存在差异。通过主成分分析和通径分析,株高和穗位高是评价裸燕麦抗倒伏能力的关键。产量较高的白燕2号、白燕18号、花早2号的株高、穗位高较低,倒伏指数较小且田间未发现倒伏;坝莜14号、晋燕17号虽具有较高产量,但其株高、穗位高较高,倒伏指数较大,且田间分别表现为7级易倒伏和5级中抗倒伏。白燕2号、白燕18号、花早2号抗倒伏综合表现良好,产量高,适宜在内蒙古乌兰察布地区及类似地区推广种植。
英文摘要:
      In order to screen high-yielding naked oat cultivars with strong lodging resistance, the lodging resistance and yield of 16 naked oat cultivars were compared, and 7 traits related to lodging resistance were analyzed by principal component analysis and path analysis. The results showed that there were differences in aboveground biomass composition, main agronomic traits, second internode morphology and lodging index of stem base, yield and component factors among 16 oat cultivars. Through principal component analysis and path analysis, the plant height and ear height were the key to evaluate lodging resistance of oat. The plant height and ear height of Baiyan 2, Baiyan 18 and Huazao 2 with high yield were lower, while lodging index and did not lodge in the field. Although the yield of Bayou 14 and Jinyan 17 were higher, their plant height and ear height were higher, and the lodging index was larger, and were lodging grades in the field were 7(easy lodging) and 5(medium lodging resistance), respectively. In conclusion, Baiyan 2, Baiyan 18 and Huazao 2 showed good lodging resistance and high yield, and were suitable for popularization and planting in Ulanqab area of Inner Mongolia and similar areas.
