花生新品种开农172丰产稳产性分析

Analysis on high and stable yield of a new peanut variety Kainong 172

以2011—2012年全国北方片花生区域试验的9个品种在16个试验点的产量数据为材料,利用基于GenStat的GGE Biplot双标图法分析参试品种的丰产、稳产和区域适应性。结果表明:全国北方片花生16个试验点可分为3个类型区,在3个类型区表现最好的4个品种分别为P09-2、开农172、粮花2号和青花1号。在9个花生品种中,P09-2、开农172和粮花2号在区域试验中具有较好的丰产性和稳产性,且适宜种植的试验点较多。开农172丰产性和稳产性均居参试品种前3位,是花生生产上具有推广价值的品种,适宜在河南、山东、河北等相似生态区开展春播和麦套种植。

This experiment used the yield data of 9 peanut cultivars in the northern China from 2011 to 2012 at 16 regional test sites, and used the GGE Biplot model in GenStat to analyze the high yield, stability and regional suitability of these cultivars. The results showed that the 16 regional test sites of peanuts in northern China could be divided into three types. The four best-performing varieties in the three types were P09-2, Kainong 172, Lianghua 2 and Qinghua 1. Among the 9 peanut varieties, P09-2, Kainong 172 and Lianghua 2 had good yield and stability in the regional test, and there were more test sites suitable for planting. The high yield and stable yield of the Kainong 172 ranked among the top 3 tested varieties. Kainong 172 was a popular variety with promotion value in peanut production and was suitable for spring sowing and interplanting with wheat in similar ecological areas such as Henan, Shandong and Hebei.
