高产大果花生新品种开农705的选育及丰产性稳产性分析

Breeding and Analysis of New High and Stable Yield Peanut Variety Kainong 705 with Large Pod

高产大果花生新品种开农705是开封市农林科学研究院以豫花9331为母本,开农49为父本通过有性杂交系谱法选育而成。为分析开农705的丰产性、稳产性和适应性,利用基于Genstat的GGE双标图对2015~2016年国家(北方片)花生区域试验荚果产量试验数据进行分析。结果表明,开农705平均荚果产量第一稳产性第二,产量高达5584.66 kg/hm^(2),比对照增产11.98%,品种适应性较好。该品种中抗花生黑斑病、茎腐病、青枯病、锈病。百果重和百仁重分别为259.41、104.14 g,出仁率70.72%。综合分析,开农705产量高、稳产性好,结果集中、抗病性好,是理想的花生新品种。2017年通过农业农村部登记,适宜河南、山东、河北等花生种植区域春播和麦套种植。

Kainong 705 was a new peanut variety with high yield and large pod which was bred through the sexual hybridization and pedigree selection with Yuhua 9331 as the male parent and Kainong 49 as the female parent by Kaifeng Academy of Agriculture and Forestry.In order to analyze the high yield,stability and adaptability perfor⁃mance of Kainong 705,GGE biplot based on Genstat was applied to identify the pod yield data of peanut regional tri⁃als from 2015 to 2016 in north China.The results showed that the average pod yield of Kainong 705 ranked first and yield stability ranked second.The average yield was as high as 5,584.66 kg/ha,which was 11.98%higher than that of the control,and it had better adaptability.The variety was middle resistant to peanut black spot,stem rot,bacte⁃rial wilt and rust.The weight of 100-pod and 100-seed were 259.41 g and 104.14 g,respectively.The kernel per⁃cent was 70.72%.In conclusion,Kainong 705 was an ideal new peanut variety which had high and stable yield,con⁃centrated pod and strong comprehensive resistance.It was authorized by the Ministry of Agriculture and Rural Af⁃fairs of the People's Republic of China in 2017 and it was suitable for spring sowing and wheat interplanting cultiva⁃tion in peanut planting areas such as Henan,Shandong and Hebei.
