Hangjiao Huangshuai is a processing type yellow pepper F1 hybrid cultivar bred with the inbred line 032-1-2-1-1-H-H bred through space treatment as the female parent and 082-1-1-H-H free of space treatment as the male...Hangjiao Huangshuai is a processing type yellow pepper F1 hybrid cultivar bred with the inbred line 032-1-2-1-1-H-H bred through space treatment as the female parent and 082-1-1-H-H free of space treatment as the male parent. The fruit is in the shape of long finger with few wrinkles and good gloss, and tastes very spicy .The fruit has a vertical diameter of 17.5 cm, a transverse diameter of 1.6 cm, a fresh thickness of 0,20 cm and a single fruit weight of 15.6 g. It is yellowishgreen in the early maturation stage and yellow in the late maturation stage. The cultivar exhibited high resistance to pepper blight, viral diseases and powdery mildew, and showed an average yield of 56 493,0 kg/hm^2. It could be generalized in Gansu, Ningxia, Liaoning and Zhejiang.展开更多

Its fruit is early-mid maturing and in the shape of a long finger.The immature fruit is in dark-green and mature fruit is in dark-red.The average length, width and flesh thickness are 15.7, 1.9 and 0.17 cm, respectively. The yield of dry pepper is 6 750 kg/hm^2. The average contents of Vc, soluble solid and dry matter are 1.30 mg/g, 10%, and 14% respectively. The cultivar has good resistance to pepper blight, viral disease and anthracnose. It shows strong tolerance to heat, water logging and drought. It is suitable for spring field cultivation in Gansu, Xinjiang and Inner Mongolia.展开更多
