摘要:

旨在为优异玉米自交系改良及其选育杂交种、玉米种质创新提供科学依据。以国内自交系‘自340’与国外杂交种‘X1132X’的优良单株(S1)回交构建基础材料,利用优系聚合和高大严选育方法经过7代自交培育出优良多抗玉米自交系‘浚696’。该自交系抗粗缩病、茎腐病、南方锈病、大斑病、小斑病等多种病害;果穗筒形、大小均匀一致,穗行数18-20行;株型紧凑,配合力高,制种产量高,适应性广。利用‘浚696’自交系组配育成的‘永优1573’和‘永优1583’两个玉米杂交种通过国家或省级审定。这两个新品种在中国黄淮海夏玉米地区及内蒙古自治区中晚熟区域生产上大面积推广应用,取得较好的社会经济效益。

Abstract:

The aim is to provide a scientific basis for the improvement of excellent maize inbred lines, the breeding of hybrids and the innovation of maize germplasm. The base material was constructed by backcrossing the domestic inbred line ‘Zi340’ with the excellent single (S1) of the foreign hybrid ‘X1132X’, and the excellent multi-resistant maize inbred line‘Xun696’ was bred by selfing after 7 generations using the superior line aggregation and high and large strict selection methods. ‘Xun696’ had multi-disease resistance to corn rough dwarf,stem rot, southern corn rust,corn northern leaf blight and corn southern leaf blight. It had fruiting spikes cylindrical, uniformity of size and kernel row number 18-20. It also had compact plant tape,strong combining ability, high seed production yield and wide range of adaptability. Two corn hybrids including ‘Yongyou1573’ and ‘Yongyou1583’ from ‘Xun696’ inbred line combination were approved by the National or Provincial Crops Variety Approval Committee. These two new varieties have been popularized and applied on a large scale in Huanghuaihai summer maize region and middle and late maturity zone of Inner Mongolia Autonomous Region, and have achieved better social and economic benefits.
