定豌8号旱地豌豆新品种,系以A909为母本,7345为父本,采用有性杂交和系谱选育法培育而成。在2007—2009年多点试验中,15点(次)折合平均产量1 908.75 kg·hm-2,较对照品种定豌4号增产18.64%,产量表现稳定高产。定豌8号平均株高65.24 cm,主茎节数12.0节,单株有效荚数4.38个,单荚粒数4.02粒,百粒重21.30 g,经济性状优良。生育期90 d左右。干籽粒粗蛋白含量26.93%,赖氨酸含量1.38%,粗脂肪含量0.902%,粗淀粉含量57.52%。抗旱、耐根腐病、丰产稳产性好,适宜在甘肃中部干旱、半干旱地区以及同类地区推广种植。
Ding pei 8 dry pea new varieties, the Department of A909 as the female parent, 7345 as the male parent, using sexual cross and pedigree selection breeding method. In the multi-point experiment from 2007 to 2009, the average yield at 15 o’clock (time) was 1 908.75 kg · hm-2, which was 18.64% higher than that of the control pea 4 and the yield was stable and high yield. The average plant height of Dingzao 8 was 65.24 cm, the number of main stems was 12.0, the effective pods per plant were 4.38, the number of single pod was 4.02 and the weight of one grain was 21.30 g. The economic characters were excellent. Growth period of 90 d or so. The crude protein content was 26.93%, lysine content 1.38%, crude fat content 0.902% and crude starch content 57.52%. Drought resistance, root rot resistance, high yield and good stability, suitable for planting in the arid, semi-arid areas and similar areas in central Gansu.
