中国农科院甜菜研究所育成的甜研303、甜研202两个新品种,于1991年2月经黑龙江省农作物品种审定委员会正式命名推广。甜研303(原代号83315)是由四倍体甜425与二倍体甜202杂交育成的多倍体新品种。该品种表现丰产性能稳定、含糖较高、抗褐斑病、耐根腐病、适应性广。在1987～1990年的省区域试验中表现突出,产糖量比对照品种增产17.0％～25.2％,含糖率提高0.6～1.0度。褐斑病感病级数降低0.5级。该品种适合在黑龙江省肇东、明水、依安、拜泉、林甸、呼兰、阿城等地及黑龙江垦区种植。在全国甜菜品种区试中名列前茅,并已在吉林、内蒙、新疆等地进行生产示范,是一个很有增产增糖潜力的优良品种。
Chinese Academy of Agricultural Sciences beet Institute bred sweet study 303, sweet study 202 two new varieties, in February 1991 by the Heilongjiang Province Crop Variety Approval Committee officially named promotion. Sweet research 303 (original code 83315) is a new polyploid breed of tetraploid sweet 425 and diploid sweet 202. The variety performance of high yield stability, high sugar, resistance to brown spot, root rot resistant, wide adaptability. In the 1987 ~ 1990 provincial regional tests, the yield of sugar increased 17.0% ~ 25.2% and the sugar content increased by 0.6 ~ 1.0% compared with the control. The brown spot susceptible series is reduced by 0.5 grade. The variety is suitable for cultivation in Zhaodong, Mingshui, Yi’an, Baiquan, Lindian, Hulan, Acheng and other places in Heilongjiang Province and reclamation areas in Heilongjiang Province. In the national beet varieties in the region among the best test, and has been in Jilin, Inner Mongolia, Xinjiang and other places for production demonstration, is a lot of sugar yield potential varieties.
