- 摘要:
- 豆科绿肥根系发达且穿透力较强，庞大的根系可以疏松土壤，培肥地力。科合202属于小粒豆，是适用于豆科绿肥、芽豆等的专用大豆新品种，由黑龙江省农业科学院，以引进俄罗斯的大豆材料HZDD1424为母本、加拿大大豆材料HZDD3796为父本，经过有性杂交选育而成。经农业农村部谷物品质监督检验测试中心（哈尔滨）检测，粗蛋白质(干基)含量达41.03%、粗脂肪(干基)含量达18.79%。于2021年通过黑龙江省农作物品种审定委员会审定（审定编号：黑审豆20210040），生育日数120 d，适应于黑龙江省第二积温带区域种植。
- Abstract:
- Leguminous green manure has a well-developed root， and its huge root can increase soil porosity and improve soil fertility. Kehe 202 is a small seed variety， suitable for new special soybean variety such as leguminous green manure and sprout bean. It was bred by the Heilongjiang Academy of Agricultural Sciences through hybridizing with the imported Russian soybean material HZDD1424 as the female parent and Canadian soybean material HZDD3796 as the male parent. The crude protein content of Kehe 202 was 41.03% and the crude fat content was 18.79% tested by the Grain Quality Supervision and Testing Center (Harbin) of the Ministry of Agriculture. This variety was approved by the Heilongjiang Province Crop Variety Approval Committee in 2021(Validation No. was Heilongjiang Beans 20210040)， with 120 d of the growth period. It was suitable for planting in the second accumulated temperature zone of Heilongjiang Province.
