以S9107为母本，草原12号为父本，采用有性杂交技术和系谱选育法，培育出旱地豌豆新品种定豌9号。在2012 — 2014年多点试验中，3 a 15点(次)折合平均产量2 064.0 kg/hm2，较对照品种定豌4号增产12.14%，产量表现稳定、高产。平均株高73.3 cm，主茎节数13.9节，单株有效荚数4.03个，单荚粒数3.86粒，百粒重20.5 g，经济性状优良。生育期92 d左右。干籽粒含粗蛋白258.1 g/kg、赖氨酸13.2 g/kg、粗脂肪7.67 g/kg、粗淀粉600.0 g/kg。抗旱、耐根腐病、丰产稳产性好。适宜在甘肃中部干旱、半干旱地区及其同类地区种植。

With S9107 as the female parent and Grassland 12 as the male parent， a new dry land pea cultivar Dingxu 9 was developed by using sexual hybridization technology and pedigree selection method. In 2012 — 2014， the average yield in 3 a 15 sites(times) was 2 064.0 kg/hm2， 12.14% higher than the control Dingwan 4 in Multipoint Test. The plant height is 73.3 cm， node numbers of main stem is 13.9， effective pods per plant is 4.03， grains per pod is 3.86， 100-seed weight is 20.5 g， the growth period is 92 days and the economic character is good. The content of crude protein， lysine， crude fat， starch content in dry seeds are 258.1 g/kg、 13.2 g/kg、 7.67 g/kg、 600.0 g/kg， respectively. It is drought resistance， root rot resistance， high yield and stable yield. It is suitable to be grown in arid and semi-arid areas in central Gansu and similar areas .
