基于GGE双标图的油菜新品种陕油1609丰产稳产适应性分析

Analysis on the High and Stable Yield,and the Adaptability of New Rapeseed Variety Shanyou1609 Based on GGE Biplot

为有效挖掘陕油1609的生产潜力,实现大面积推广应用,采用GGE双标图对2016年、2017年国家冬油菜黄淮区22个参试品种进行了丰产、稳产和适应性分析,并且结合重要的农艺、品质、抗逆等性状对陕油1609进行综合评价。结果表明,1)陕油1609在平均环境轴(AEA)上最接近正方向,丰产性突出,稳产性较好。2)陕油1609理想程度排名第一。3)陕油1609适应性广,尤其在陕西杨凌、富平、宝鸡、大荔、河南郑州、甘肃成县6个试验点均表现良好,适宜种植。4)与对照秦优7号相比,陕油1609在冬油菜黄淮区种植优势明显。5)陕油1609含油量高、优质、多抗、适合机械化生产。在冬油菜黄淮区组参试品种中,陕油1609是兼有丰产性、稳产性和广适性的优良品种,本研究可为采用GGE双标图法综合评价其他作物的数量性状提供借鉴。

In order to effectively explore the production potential of Shanyou 1609 and realize its large-scale popularization and application,the GGE biplot was used to analyze high yield stability and adaptability of 22 tested varieties of National Winter Rapeseed in Huanghuai region in 2016 and 2017,and comprehensively evaluated Shanyou1609 in combination with important agronomic,quality and resistance traits.The results showed that:Shanyou1609 was closest to the positive direction on the average environmental axis(AEA),with outstanding yield and good stability.The ideal degree of Shanyou1609 ranked first.Shanyou1609 had a wide adaptability,especially in Yangling,Fuping,Baoji,Dali of Shaanxi,Zhengzhou of Henan and Chengxian of Gansu in which it performed well and was suitable for planting.Compared with the control'Qinyou7',Shanyou1609 had obvious advantages in planting Winter Rapeseed in Huanghuai region.Shanyou 1609 had high oil quality,better quality multi-resistant,suitable for mechanized production.In summary,Shanyou1609 was an excellent variety with high yield,stable yield and wide adaptability among the tested varieties of National Winter Rapeseed in Huanghuai region group.This study could also provide reference for the comprehensive evaluation of quantitative traits of other crops by GGE biplot analysis.
