“沪单七号”玉米新品种(即150×E_(28),组合)是上海市农科院作物所和崇明县种子公司共同选育而成的黄粒玉米单交种。经1986～1988年鉴定试验、区域试验和生试验,以及崇明县产大面积生产示范,证明该品种高产、稳产、适应性好、抗逆性强,且品质优良,深受农户欢迎。现将其选育经过,产量表观,特征特性等综述如下: 一、选育经过与产量表现“沪单七号”的母本“150”是我所从优良玉米种“中单二号”中自交分离选育而成的自交系,它配合力高,抗叶斑病强。父本“E_(28)”是辽宁省丹东市农科所育成的具有抗大斑病Ht基因的自交系,该两个自交系都具有配合力高和抗病性强的特点,两自交 “Shanghai No. 7” new maize varieties (ie 150 × E_ (28), combination) is the Shanghai Academy of Agricultural Sciences Crops and Chongming County seed co-breeding yellow maize single cross. After 1986 ~ 1988 appraisal test, regional experiment and raw test, as well as Chongming County, large-scale production demonstration to prove that the variety of high yield, stable yield, good adaptability, strong resistance, and good quality, welcomed by farmers. Now after breeding, the apparent yield, characteristics and characteristics are summarized as follows: First, after breeding and production performance “Shanghai No. 7” the mother of “150” is my good corn from the “single number two” Inbred lines inbred and self-bred, with high combining ability, strong resistance to leaf spot. The male parent “E_ (28)” is an inbred line with Ht gene resistant to Dictyophora bred in Dandong City, Liaoning Province.
