Abstract: In order to gain an in-depth understanding of the parent selection of Hefeng（Hejiao, Henong and Jiadou） series of soybean varieties, this paper analyzed the parents involved in the breeding of soybean varieties from the Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences, and summarized the past parents. Experience is selected to provide technical guidance for future variety improvement and innovation. As to 2022, Jiamusi Branch has bred 119 new soybean varieties, including 3 hybrid soybean varieties. 124 parents were involved, including 11 domestic ancestral parents, 13 foreign parents and 100 domestic direct parents（innovative germplasm and breeding varieties）; 46 important parents or core parents（bred varieties≥2）, 78 common parents（1 bred variety）. Among them, Beifeng 11 and Hefeng 50 has bred 9 varieties respectively; Mancangjin has bred 7 varieties; Hefeng 34 and Hefeng 35 has bred 6 varieties respectively; Heihe 45 and Beidou 5 and HOBBIT has bred 5 varieties respectively; Heihe 43, Henong 69, Hefeng 55, Kenfeng 16 and Heihe 38 has bred 4 varieties respectively; Tujiazi, Jingshanpu, Ke 4430-20, Hefeng 26, Suinong 10, Huajiang 4, Heihe 35, Henong 71, American fasciated stem soybean, Japanese small soybean and Heinong 54 has bred 3 varieties respectively; Heihe 54, Heilongjiang 41（Russia）, Hefeng 24, Gang 201, Ohio, Suinong 14, Gong 84112-1-3, Hefeng 39, Hefeng 41, Hefeng 42, Hefeng 51, Hefeng 57, Beifeng 9, Jiufeng 10, He 93-793, Kennong 19, Henong 68, Heinong 48, Keshan 1, Sui 02-529 and Heijiao 01-1032 has bred 2 varieties respectively. Among the parental sources selected by the branch, the peasant varieties（local varieties） accounted for 8.87% of the total number of parents, the institution bred parent materials accounted for 34.68% of the total parents, the domestic parent materials（Heilongjiang, Jilin, Liaoning and Inner Mongolia）,accounted for 46.03% of the total parents, the overseas parent materials（USA, Japan, Russia and Italy）, accounted for 10.48% of the total parents. In these parent materials, 5 super early maturities, 3 extremely early maturities, 42 early maturities, 63 mid-early maturities, 1 mid maturity, 9 mid-late maturities and 1 late maturity were included. The analysis results showed that the parents selected by the branch are from a wide range of sources, are geographically distant and ecologically different, genetic basis improvement and genetic diversity, authentic lineage and blood relationship widening, which ensure the innovation and improvement of the level of variety improvement. This practice and experience is worthy of promotion and reference.
