Breeding Research of A New Super Early Maturing Soybean Variety Henong 36

Jiadou 36 is an excellent variety bred by Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences with Henong 69 as the female parent and Huajiang 2 as the male parent by combining cross breeding and molecular design breeding. It was approved and popularized by the National Crop Variety Approval Committee in 2020. This variety has accumulated and aggregated excellent genes and traits from its parents such as early maturity, high yield, high quality and stress resistance, which shows super early maturity, high and stable yield, high quality, good stress resistance and strong adaptability. It has effectively solved the outstanding problems of low yield per unit area and poor quality of super early maturing varieties, and has great application value and potential. This paper introduce the breeding process of this variety and the corresponding key points of high-yield cultivation techniques. At the same time, it discusses and summarizes the problems of parent selection, cross combination method, early maturity selection, ecological selection, seed selection and planting density in super early maturing breeding, in order to provide theoretical basis and technical guidance for super early maturing soybean breeding.
