玉米杂交种畅玉99的选育及创新

Breeding and Innovation of Hybrid Maize Variety Changyu 99

为了促进综合农艺性状优良、产量高、适应性广的中晚熟玉米新品种畅玉99的推广应用,本文简要介绍了其选育经过、特征特性、产量表现。畅玉99由山西农业大学玉米研究所以XL03-16为母本,A16为父本,于2012年组配而成。2017-2018年参加山西省春播玉米中晚熟区域试验,平均产量为13695.8 kg·hm-2,比对照先玉335增产8.1%;2018年参加山西省春播玉米中晚熟自主生产试验,平均产量为13246.5 kg·hm-2,比对照先玉335增产9.1%。畅玉99具有耐密、多抗、高产稳产、优质的优点,淀粉含量为76.96%,属高淀粉品种,适宜在山西春播中晚熟区及同一生态区种植。

In order to promote the popularization and application of Changyu 99,a new mid late maturing maize variety with excellent comprehensive agronomic characters,high yield and wide adaptability,this paper briefly introduced breeding process,characteristics and yield performance of Changyu 99.Changyu 99 was bred with XL03-16(female)and A16(male)by Maize Research Institute of Shanxi Agricultural University in Xinzhou City in 2012.With Xianyu 335 as contrast,the average yield of Changyu 99 was 13695.8 kg·hm-2(increasing by 8.1%)in area trials of middle-late maturing maize in Shanxi Province during 2017-2018,and the average yield was 13246.5 kg·hm-2(increasing by 9.1%)in production trials of middle-late maturing maize in Shanxi Province in 2018.This variety Changyu 99 had resistance to high density,multi-resistance,high yield,steady yield and good grain quality.The starch content(high-starch maize)was 76.96%.It was suitable to be planted in mid late maturing maize areas in Shanxi and same ecological areas.
