Abstract:
In response to the relatively limited number of vegetable soybean varieties, slow replacement speed, and shortage of high-quality varieties in Shanxi Province, Jinke 2 is a new variety of vegetable soybean selected by the College of Agriculture, Shanxi Agricultural University through pedigree selection, Jinyi 38 was used as female parent and Xinmaodou 1 as the male parent. Jinke 2 participated in the regional experiment of spring sowing group of the national vegetable soybean in 2019. The average fresh pod yield was 14 703.1 kg·ha
-1, increased 19.6% more than that of Zhexiandou 5(CK), ranking first among the tested varieties. In 2020, the average fresh pod yield was 12 521.4 kg·ha
-1, an increase of 8.8% compared to the control Zhexiandou 5(CK), ranking third among the tested varieties. The average fresh pod yield of 2019-2020 years was 13 612.25 kg·ha
-1, which was 14.4% more than Zhexiandou 5(CK). The average fresh pod yield of Jinke 2 was 12 265.5 kg·ha
-1 increased 7.2% more than that of Zhexiandou 5(CK) in production test in 2021, ranking second among the tested varieties. Its crude protein content is 44.06%, the crude fat content is 19.39%, and the total soluble sugar is 4.9%. The taste is faint scent, and a strong sweet taste. It is either soft or crispy, and has a medium glutinous texture with a good flavor. Its approval number is Jinshendou 20170008 and Guoshendou 20220048. Jinke 2 has a distant genetic relationship with its parents, the breeding in disease gardens and different key point of offspring during the breeding process, so Jinke 2 has the characteristics of high yield, high quality, and disease resistance. Jinke 2 has a wide range of application prospects.
