Which new pea varieties are suitable for planting in Qujing

Pea is an important crop for crop rotation and soil improvement. The perennial planting area of pea in Qujing is 13333 hm2, second only to broad bean and ranking second among food legumes. Because pea breeding in Qujing started relatively late, farmers mostly plant local old varieties, with seed exchange and mixing and serious variety mixture. In production, there is a lack of breakthrough varieties with multiple resistance, high quality and high yield. The dry seed yield is mostly 1300-1800 kg/hm2, so the role of pea in agricultural production and the adjustment of the planting structure has not yet received due attention. In view of the actual situation of pea production, the Characteristic Crop Research Institute of Qujing Academy of Agricultural Sciences, after years of selection, testing and demonstration, has bred and screened out several new pea varieties suitable for planting in Qujing.

1 New grain-type (dry seed harvest) pea varieties

1.1 Jingwan No. 1

1.2 Jingwan No. 2

Bred by the Characteristic Crop Research Institute of Qujing Academy of Agricultural Sciences. It is a medium-maturity variety with a growth period of 164 d, semi-vining plant type, common leaf type, plant height 82.1 cm, branch number 2.5 branches/plant, effective branches 2.2 branches/plant, white flowers, good pod setting, filled pods 11.7 pods/plant, filled seeds 45.0 seeds/plant, seeds per pod 3.6 seeds/pod, 100-seed weight 21.9 g, dry seed yield per plant 7.8 g, average yield 2458.5 kg/hm2, seed shape spherical, seed color green, stable genetic traits, consistent morphological characteristics and biological characteristics, good overall field evaluation, with excellent traits such as high quality and high yield, wide adaptability and strong stability, medium resistance to powdery mildew, suitable for planting in the main pea production areas of Yunnan Province at an altitude of 1400-2400 m, with broad market prospects and good value for promotion and utilization.

1.3 Yunwan No. 17
