Breeding Research of A New National Approved Vegetable Soybean Variety Jinke 2
摘要
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 was14 703.1 kg·ha-1,increased19.6%more than that of Zhexiandou5(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 increased7.2%morethanthatof Zhexiandou5(CK)inproductiontestin2021,rankingsecondamong 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.关键词
