【摘要】 PN78599是20世纪80年代后期由美国先锋公司引入到我国的优良玉米杂交种,因其一般配合力高、品质优、抗倒伏、抗叶病表现突出,全国各大育种单位相继以其为基础材料直接或间接选育出一批优良自交系应用到生产,组配出一批高产、高抗、优质的玉米新品种,为我国的玉米育种和生产做出了很大贡献。其中主要利用的杂优模式为P群与塘四平头群、旅犬红骨群、瑞德群、兰卡斯特群等。随着育种目标的调整,如何继续沿用原有的杂优模式和创建新的杂优模式值得育种家高度重视,为中国育种和生产再上新的台阶奠定基础。更多还原

【Abstract】 PN78599 the late 20th century,80 was introduced from the U.S.Pioneer,which belonged to tropical corn hybrids,because of its high general combining ability,good quality,lodging resistance,outstanding resistance to leaf disease,the major breeding units have been based on material in its Breeding of a group,directly or indirectly applied to the production of inbred lines,the group with a group of high - yield,high resistance,high - quality new varieties of maize for maize production in China has made great contributions. The main use of Heterotic Patterns for PN78599 group germplasm cross Sipingtou,Lu da reid cob group,Reid group,Lancaster group etc.With the breeding goal adjustment,how to continue to use the original hybrid mode and create a new model of heterosis breeding home worthy of attention,for the Chinese breeding and production to a new level lay the foundation.更多还原
