【摘要】 以晋北地区近年来种植范围较广的5个燕麦品种为试验材料,通过对其生育期、植株形态特征、抗性、产量性状及品质性状等指标进行分析,以筛选出适宜晋北地区种植的优良燕麦品种。结果表明,坝莜3号生育期最长,达100 d;参试燕麦品种的各植株形态特征均以坝莜18号最佳;晋燕17号、坝莜1号和坝莜18号的抗旱性、抗倒伏性和抗病性都较强;坝莜18号的穗粒质量和千粒质量均最大,分别为1.8、26.0 g;品种间产量差异较大,其中,坝莜18号产量最高,为2 703.0 kg/hm~2;坝莜18号的淀粉含量和β-葡聚糖含量均最高,分别为541.69 mg/g和4.85%。综合分析认为,坝莜18号最适合在晋北地区种植。更多还原

【Abstract】 Five oat varieties with wide planting area in recent years in northern Shanxi province were used as experimental materials. Through the analysis of their growth period, plant morphological characteristics, resistance, yield and quality characters,excellent oat varieties suitable for planting in northern Shanxi were selected. The results showed that the growth period of Bayou 3 was the longest, reaching 100 d. Bayou 18 was the best variety for the morphological characteristics of all oat varieties. The drought resistance,lodging resistance and disease resistance of Jinyan 17, Bayou 1 and Bayou 18 were all very strong. The ear grain quality and 1 000-grain quality of Bayou 18 were the highest, which were 1.8, 26.0 g, respectively. The difference of yield among varieties was large, the yield of Bayou 18 was the highest, which was 2 703.0 kg/hm~2. The starch content and β-glucan content of Bayou 18 were the highest, which were 541.69 mg/g and 4.85%, respectively. The comprehensive analysis shows that Bayou 18 is the most suitable for planting in north Shanxi.更多还原
