基 金:甘肃省科技重大专项计划“甘肃省小杂粮新品种选育与示范”燕麦课题(18ZD2NA008);白银市科技计划项目“燕麦种质资源鉴定及新品种选育”(2023-1-1N)。
摘 要:为深入分析白银市沿黄河灌区燕麦品种的综合生产性能、丰产潜力及其影响因素,试验选取适宜水浇地种植的18个燕麦品种(系)的16个指标进行灰色关联度、主成分分析、相关和通径分析。结果表明,农艺性状中与籽粒产量相关系数居前5位的依次是成穗数(0.45)、千粒重(0.40)、单株粒重(0.15)、叶茎比(0.09)、株高(0.08);与干草产量相关系数居前5位的依次是生育期(0.73)、株高(0.60)、叶茎比(0.47)、主穗长(0.44)、千粒重(0.43);籽粒产量与各性状关联度前3名为生育期>千粒重>单株粒重。干草产量与各性状关联度前3名为成穗数>旗叶长>苗数。综合评判,银燕8号、银燕6号、航燕1号适宜作为粮用籽粒型燕麦;定燕2号、银燕9号适宜作为饲用麦草型燕麦品种示范推广、开发应用。In order to deeply analyze the comprehensive production performance,high yield potential,and influencing factors of oat varieties in the irrigation area along the Yellow River in Baiyin,the experiment selected 16 indexes of 18 oat varieties(lines)suitable for planting in irrigated fields for gray correlation degree,principal component analysis,correlation,and path analysis.The results showed that among the agronomic traits,the top five correlation coefficients with grain yield were ear number(0.45),1000-grain weight(0.40),grain weight per plant(0.15),leaf-stem ratio(0.09),and plant height(0.08);The top five correlation coefficients with hay yield were growth period(0.73),plant height(0.60),leaf-stem ratio(0.47),main ear length(0.44),1000-grain weight(0.43);The top three traits associated with oat seed yield were growth period>1000-grain weight>single plant grain weight.The top three traits associated with oat hay yield were number of ears>flag leaf length>seedling number.According to the comprehensive judgment,Yinyan 8,Yinyan 6,and Hangyan 1 are appropriate for grain seed type oat varieties,while Dingyan 2 and Yinyan 9 are appropriate for the demonstration,promotion,and application of forage and grass oat varieties.
