摘要
以引进的5个燕麦品种为试验材料,对植株形态特征进行观察,测定了生育期、株高、穗长、小穗数、单株粒数、单株粒质量、千粒质量和籽粒产量,并采用灰色关联度分析方法对8个性状进行综合评价,以筛选适宜在晋北地区种植的燕麦品种。结果表明,5个燕麦品种在晋北地区均能成熟;远杂2号株高最高,达到130.7 cm;远杂2号的穗长最长,为17.9 cm;坝莜13号的小穗数最多,为63.4个,但与其他品种无差异;坝莜13号的单株粒数最多,为171.2个;坝莜13号单株粒质量最大,为3.51 g;远杂2号的千粒质量最高,达25.66 g;坝莜14号3 a平均产量最高,为3 383.33 kg/hm^(2),燕科2号平均产量最低,为2 777.78 kg/hm^(2)。各农艺性状的权重依次为生育期>产量>穗长>小穗数>株高>单株粒数>千粒质量>单株粒质量。远杂2号的加权关联度最大,坝莜13号次之,坝莜14号、燕科2号和定莜9号的加权关联度分别位列第3~5位。灰色关联度综合鉴定表明,远杂2号和坝莜13号2个品种在生产性能上表现良好,适宜在晋北地区进行推广种植。
In order to select the oat varieties suitable for being planted in the north region of Shanxi Province, five oat varieties were used as materials to observe plant morphological characteristics. The growth duration, plant height, spike length, spikelet number, grain number per plant, grain weight per plant, 1000-grain weight and grain yield were determined and given a comprehensive evaluation by grey correlation grade analysis. The results showed that all five oat varieties matured in the northern Shanxi. The plant height of Yuanza 2 was the largest and spike length was the longest, which were 130.7, 17.9 cm, respectively. The spikelet number of Bayou 13 was up to 63.4, though no significant difference was there between it and other varieties. Bayou 13 had the most grain number per plant, which was 171.2. The grain weight per plant of Bayou 13 and 1000-grain weight of Yuanza 2 were the highest, reaching 3.51 g and 25.66 g, respectively. The highest average yield of Bayou 14 in 3 years was 3 383.33 kg/hm;, while the lowest average yield of Yanke 2 was 2 777.78 kg/hm;. The weights of agronomic traits in the grey correlation grade analysis were ordered as growth duration>yield>spike length>spikelet number>plant height>grain number per plant>1000-grain weight>grain weight per plant. The weighted correlation degree of Yuanza 2 was the largest,followed by Bayou 13, then by Bayou 14, Yanke 2 and Dingyou 9, which were in the third to fifth place respectively on the list. The comprehensive evaluation of grey correlation grade showed that Yuanza 2 and Bayou 13 were more suitable for being planted in the northern Shanxi.
