Research on the Breeding of Processing Specific Double Green Soybean Qinonglü 1
With the increasing demand for special double green soybean varieties with green seed coat and cotyledon as commodity raw materials in soybean production and market,the existing approved double green soybean varieties and annual commodity output cannot meet production and market needs,especially the renewal speed and breeding quantity of the new soybean varieties are not as fast as ordinary types of varieties.The existing varieties used in production are relatively single,andthe old varieties are planted continuously in production,resulting in the degradation of species.The weakened resistance to diseases,pests,and weeds has led to a decrease in yield and variety,which hinders the development of the double green soybean industry.In response to the existing problems,the soybean research team of Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences has carried out breeding work for green seed coat and cotyledon soybean,and breeding of Qinonglti 1,which belongs to the special green seed coat green cotyledon soybean variety.Suitable for planting in the fourth temperate zone of Heilongjiang Province with an active accumulated temperature of ≥ 10 ℃ and 2 250 ℃.The number of days from seedling emergence to mature growth in the adaptation zone is about 113 days.The plant is about 89 cm tall,with branches,white flowers,pointed leaves,and a suboptimal podding habit.It is gray hairy and has curved sickle shaped pods.When mature,it is brown in color,with round seeds and a glossy green seed coat.The hilum is brown,and the 100-seed weight is about 20.6 g.The average regional trial production from 2020 to 2021 was 2 630.4 kg·ha-1,increased yield by 9.8％compared to the control variety Guangshi green soybean 1.It is mid-resistant to gray spot disease.The average protein content is 39.39％,and the fat content is 20.04％.Through the cultivation of this variety,it not only provides new variety support for the production of special double green soybeans,meets the market demand for new varieties,enhances the contribution of the variety to the industry,but also provides excellent parental resources for double green soybean breeding,expands the genetic foundation,and accelerates the cultivation speed of new double green soybean varieties.
