Breeding of a New Kidney Bean Variety Jizhangyun 2 with High Yield and Erect Type and Its Application
[Objective]The study aimed to breed high-quality and high-yield conventional kidney bean varieties to meet the current market demand for high-quality and yield kidney beans.[Method]Jizhangyun 2,a new kidney bean variety with high-quality and yield,was successfully bred by Zhangjiakou Academy of Agricultural Sciences through crossing American excellent resource kidney bean 15-3-9(female parent)and Bashang red kidney bean(male parent)based on pedigree method.The achievement evaluation was conducted in 2021,and the evaluation number was Zhangkekaipingzi[2021]No.63.[Result]The two-year average yield of Jizhangyun 2 in the regional trial of Zhangjiakou from 2016 to 2017 was 2 049.31 kg/hm2,with an increase of 10.55%compared with CK(Yingguohong).The two-year average yield of Jizhangyun 2 in the production experiment was 1 903.83 kg/hm2,which increased by 11.21%compared with CK(Yingguohong).Jizhangyun 2 had a crude protein content of 28.64%,crude fat content of 1.21%,and crude starch content of 43.58%in dry seeds.[Conclusion]Jizhangyun 2 is a high protein kidney bean variety with high quality and yield,large and uniform grains,good commodity,drought and barren resistance,strong disease resistance and good adaptability,which is suitable for planting in Northern Hebei,Shanxi,Inner Mongolia and other similar ecological areas.
