汾豌豆1号新品种选育及耐热性驯化技术研究

New Variety Breeding of Fenwandou1 and Heat Resistance Domestication Technology Research

汾豌豆1号是山西省农业科学院经济作物研究所2002年以JW-16作母本,JW-8作父本经有性杂交后多年定向选育而成的豌豆新品种。该品种在连续2010~2011年2年生产试验中均居产量试验的第1位,2年平均产量2 663 kg/hm2。经农业部谷物检测中心检测其粗蛋白（干基）25.41%,粗脂肪（干基）2.45%,粗淀粉（干基）38.57%。2012年经山西省品种审定委员会评定后正式定名为“汾豌豆1号”。该品种通过播前预冷冻、有性杂交,后代耐热性选择及栽培管护等耐热驯化技术成为一个冬性特征弱化的豌豆新品种,适宜山西省北中部及同纬度地区春播。

In 2002, new variety of Fenwandoul was bred from the female parent JW-i6 and male parent JW-8 in Economic Crops Institute of Shanxi Academy of Agricultural Sciences. This variety topped the first in production test during 2010 -2011. The average yield of two years was 2 633 kg/hm2, the detection results showed that protein （dry basis） is 25.41% , crude fat （dry basis） is 2.45% , crude starch （dry ba- sis） is 38.57% by Grain Quality Testing Center of the Ministry of Agriculture, assessed officially named as ＂Fenwandou 1＂ by Variety Ap- proval Committee of Shanxi Province in 2012. Through pre-sowing frozen, sexual hybridization, selection of offspring heat resistance and culti- vation, a new variety of pea with the weakening of winter characteristic was obtained, which is suitable for spring sowing in north central area of Shanxi Province and the same latitude area.
