摘要: 【目的】筛选适合内蒙古乌兰察布市栽培的裸燕麦品种(品系),为该地区的燕麦引种、品种选育及新品种示范推广奠定理论基础。【方法】以全国新选育出的12个裸燕麦品种(品系)为供试材料,采用单因素随机区组试验,对不同燕麦品种(品系)的生育期、主要农艺性状、产量和品质性状进行分析。【结果】参试的12个裸燕麦品种(品系)均能在当地正常成熟。主要农艺性状表现较好的品种(品系)有:201229-1-2、张莜8号、坝莜18号,坝莜18号在株高(136.10 cm)、主穗长(22.03 cm)、穗粒重(2.94 g)、分蘖数(3.58个)、千粒重(30.14 g)上表现较好;201229-1-2在分蘖数(4.20个)、小穗数(35.73个)、穗粒重(2.06 g)上表现较好;张莜8号在千粒重(30.14 g)上表现较好。产量表现较好的品种(品系)有坝莜18号、201229-1-2、白燕16号,分别为3 250.05、3 330.00、3 157.80 kg/hm2。品质性状表现较好的品种(品系)有张莜9号(蛋白质含量最高,为16.57%)、晋燕18号(β-葡聚糖含量最高,为5.00%)、魏都莜5号(淀粉含量最高,为61.98%)、201229-1-2(粗脂肪含量和籽粒容重最高,分别为5.51%、709.00 g/L)。主成分分析评价表明,坝莜18号、白燕16号、张莜8号、201229-1-2号综合得分较高,产量性状和营养品质性状均相对较为突出。【结论】综合性状较好的裸燕麦品种(品系)有坝莜18号、白燕16号、张莜8号、201229-1-2,适宜在内蒙古乌兰察布市推广种植,尤以坝莜18号突出。

Abstract: 【Objective】To screen naked oat varieties(lines) suitable for cultivation in Ulanqab City,Inner Mongolia and lay a theoretical foundation for the introduction of oat varieties,breeding,demonstration and promotion of new varieties in the area.【Methods】Using 12 newly bred naked oat varieties(lines) in China as experimental material,in single factor randomized block experiments,the growth period,main agronomic traits,yield and quality traits of the different oat varieties(lines) were analyzed.【Results】All of the 12 naked oat varieties(lines) tested could mature normally in the local area. The varieties(lines) with better main agronomic traits were:201229-1-2,Zhangyou No.8,Bayou No.18. Bayou No.18 had better performance in plant height(136.10 cm),main panicle length(22.03 cm),grain weight per spike(2.94 g),tiller number(3.58) and 1000-grain weight(30.14 g). 201229-1-2 performed better in tiller number(4.20),spikelet number(35.73) and grain weight per spike(2.06 g). Zhangyou No.8 had better performance in 1 000-grain weight(30.14 g). The varieties(lines)with better yield performance were Bayou No.18,201229-1-2 and Baiyan No.16,at 3 250.05,3 330.00 and 3 157.80 kg/hm2,respectively. The varieties(lines) with better quality traits were Zhangyou No.9(highest protein content at 16.57%),Jinyan No.18(highest β-glucan content at 5.00%),Weiduyou No.5(highest starch content at 61.98%),and 201229-1-2(highest crude fat content and grain bulk density at 5.51% and 709.00 g/L). Principal component analysis showed that the comprehensive scores of Bayou No.18,Baiyan No.16,Zhangyou No.8,and 201229-1-2 were higher,with relatively prominent yield traits and nutritional quality traits.【Conclusion】The naked oat varieties(lines) with better comprehensive traits were Bayou No. 18,Baiyan No. 16,Zhangyou No. 8,and 201229-1-2. They were suitable for promotion and cultivation in Ulanqab City,Inner Mongolia,with Bayou No. 18 being particularly prominent.
