Abstract: In order to promote the renewal of soybean varieties in the northern of Heilongjiang Province and improve the yield of local soybean per unit area.This paper introduced the breeding process,characteristics and optimized cultivation techniques of a new super early maturing soybean variety Heike 57.The plant height of this variety is about 70 cm,and the weight of 100 grains is about 20 g.The protein content is 37.78%,and the fat content is 21.46%.The number of days from emergence to maturity is about 95 d,and require 1 900℃the active accumulated temperature which above≥10 ℃,which is suitable for planting in the sixth accumulative temperature zone in Heilongjiang Province.The optimum planting density of this variety is about 350 000 plants per hectare and the sowing amount of 70-75 kg per hectare was generally appropriate.This variety showed good stability and high yield in the experimental stage,and is expected to become the main cultivar in the local area.
