合丰45号是以绥农10号(绥农4号×绥7516)为母本,与垦农7号(绥农4号×合丰29号)为父本有性杂交育成的新品种,油分含量22.06%,蛋白质含量40.16%,区域试验平均产量2920.9kg/hm2,较对照品种合丰25号增产15.2%,生产试验平均产量2826.4kg/hm2,较对照品种绥农14号增产16.4%,抗灰斑病、抗疫霉根腐病、中抗病毒病,属于超高产、多抗、高油专用型品种,2003年由黑龙江省农作物品种审定委员会审定推广。本文报导合丰45号的选育与试验结果,并对关键育种技术进行探讨。
Hefeng No.45 is a new breed developed by sexual intercourse with Suinong 10 (Suinong 4 × Sui 7516) as female parent and Kenong 7 (Suinong 4 × Hefeng 29) as male parent, The average oil yield was 22.06% and the protein content was 40.16%. The average yield of regional experiment was 2920.9kg / hm2, which was 15.2% higher than that of Hefeng 25 and the average yield of 2826.4kg / hm2 in production test, 16.4% higher than that of Suinong 14, Resistance to gray leaf spot, resistance to Phytophthora root rot, moderate antiviral disease, belonging to the super-high yield, multi-resistance, high oil-specific varieties, in 2003 by Heilongjiang Province Crop Variety Approval Committee examined and popularized. This article reports the results of selection and experiment of Hefeng No.45, and discusses the key breeding techniques.
