优质早熟高产辣椒新组合“赣丰5号”的选育研究

Study on Breeding of New Hot Pepper Combination “Ganfeng 5” with Good Quality,Early Maturity and High Yield

“赣丰 5号”是以早熟抗病辣椒自交系“B940 4”为母本 ,抗病长果辣椒“B92 71”为父本配制而育成的辣味型一代杂种。该杂种早熟 ,春季栽培时从定植至采收约 40～ 45d;产量高 ,前期产量和总产量比对照“湘研 1号”分别增产 5 .6 %～ 7.0 %和 33.6 %～ 38.0 % ,一般总产量达 2 2 5 0 0～ 6 0 0 0 0kg/hm2 ;抗性强 ,抗疫病、病毒病和炭疽病 ;品质优 ,单果重量 2 5～30g,维生素C的含量达 931mg/kg(FW)。现已在江西、四川、湖北、云南、广西。

Ganfeng 5” is a hot pepper F\-1 hybrid with good quality,early maturity,strong resistance and high yield,it was bred by crossing between early-maturing and disease resistant inbred line “B9404” (female parent) and disease resistant and long-fruited inbred line “B9271” (male parent).When this hybrid is planted in spring,the duration from transplanting to harvest is about 40～45 days,the yield at earlier stage and total yield are respectively increased by 5.6%～7.0% and 33.6%～38.0% as compared with the check variety “Xiangyan 1” ,the total yield of “Ganfeng 5” reaches 22 500～60 000kg/hm\+2 generally. “Ganfeng 5” has strong resistance to hot pepper phytophthora blight,virus disease and anthracnose, its single-fruit weighs 25～30g on average,the vitamin C content in 1kg fresh fruit is 931mg.“Ganfeng 5” has been popularized and planted in Jiangxi,Sichuan,Hubei,Yunnan,Guangxi and Chongqing etc.\;
