摘要
以加拿大抗白粉病豌豆Mp1807为母本、绿子叶品种Graf为父本,通过有性杂交,采用系统法选育,多生态区试验进行丰产性、适应性以及根腐病和白粉病抗性评价,以及2012—2014年在全国春播区13个试点和冬播区8个试点进行适应性和丰产性试验,结果表明,陇豌1号耐根腐病、中抗白粉病,产量高、稳产性能好;株型紧凑,矮秆,直立生长,株蔓粗壮,抗倒伏。春播组试验平均产量2 855.25 kg/hm2,较对照增产18.39%,最高产量5 564.2 kg/hm2;冬播组试验产量2 349.90 kg/hm2,较对照增产12.75%。该品种适宜在春播区甘肃兰州及甘南卓尼、内蒙古达拉特、宁夏隆德、青海西宁、西藏拉萨以及冬播区江苏如皋、四川成都、重庆永川、江苏南京、陕西安康等地种植,特别适宜在西北灌溉农业区和年降水量在350~500 mm的雨养农业区种植。
Longwan 6 is a newly bred semi-leafless pea cultivar by parental combination of Canada powdery mildew resistant pea Mp1807 with green cotyledon cultivar Graf by means of sexual hybridization and breeding by systematic method. the high-yield and adaptability are studied and the resistance to root rot and powdery mildew are evaluated in a multi ecological experiment. In2012 — 2014,the average yield is 2 855.25 kg/hm^2,which is 18.39% higher that of the check,the highest yield is 5 564.2 kg/hm^2 at 13 spring-sown sites and the average yield is 2 349.90 kg/hm^2,which is 12.75% higher that of the check at 8 winter-sown sites.The result shows that the cultivar is characterized by lodging resistance,high yield,resistance to powdery mildew,better tolerance to root rot than current pea varieties and landraces in multi-year and multi-sites trails. It is suitable to be grown in field pea springsown areas of Lanzhou in Gansu,zhuoni of Gannan,Dalate of Inner Mongolia,Longde of Ningxia,Xining of Qinghai,Tibet Lhasa,and winter-sown areas of Rugao of Jiangsu,Chengdu of Sichuan,Yongchuan of Chongqing,Nanjing of Jiangsu,Ankang of Shaanxi and other places,especially suited to irrigation region of Northwest China and farmland areas of receiving greater than 350 ~500 mm average annual rainfall.
