Abstract: In order to fully understand the new soybean variety Henong 118,breeding and testing of this variety and pedigree analysis of its parents were summarized in this paper.The new soybean variety Henong 118 was bred by crossbreeding and molecular design breeding.The female parent was Beidou 5 and the male parent was Heihe 35.This variety was approved and promoted by national crop variety certification committee in 2020.It was a super early maturing soybean variety with growing days of 111 days and needed a accumulated temperature of 1 850℃ above 10℃．The 100-seed weight was rang 18 to 20 g.The protein content was 39.65%and oil content was 18.20%.It was medium susceptibility to SMVⅠ＆Ⅲ and resistance to phytophthora.The average yield of national regional trial was 2 176.5 kg·hm^-2,which 10.9% higher than the control variety Huajiang 2.The average yield of national production test was 2 056.5 kg·hm^-2,which 4.5%higher than the control variety Huajiang 2.There were 51 soybean materials involved to the parent pedigree composition.Such as domestic famous varieties Mancangjin,Jingshanpu,Hefeng 25,Beihudou,Beifeng 11,Heihe 3,Heihe 54,Heihe35,etc.Famous foreign varieties such as Wilkin,Tokachi-Nagah,ubilet,heilongjiang 41（Russia）,etc.Domestic excellent germplasm materials such as Kejiao 4430-20,Beijiao 69-1483,Heijiao 83-1345,etc.These excellent parent materials played a core or backbone role in the process of breed evolution and improvement.
