摘要
为了给山西省小麦生产提供抗旱、高产、优质小麦新品种,促进小麦更新换代,实现小麦持续增产稳产。以运旱20410为母本、运旱719为父本进行杂交,通过水旱交叉生态选择、多环境多点鉴定等手段,采用系谱法成功选育出了抗旱冬小麦新品种晋麦105号。2017—2019年参加山西省南部中熟冬麦区旱地组品种区域试验,2 a 13点(次)平均折合产量为4 396.28 kg/hm^(2),较对照品种晋麦47号增产6.7%。2018—2019年度参加山西省南部中熟冬麦区旱地生产试验,7个试点平均折合产量为4 158.77 kg/hm^(2),比对照品种晋麦47号增产6.1%。该品种株高73.6 cm,穗长6.8 cm,成穗数480.0万穗/hm^(2),穗粒数31.0粒,千粒重38.5g;中感条锈病,中感叶锈病,中感白粉病。适宜在山西省南部麦区旱地、黄淮旱地麦区、陕西渭北旱塬麦区及同类生态类似区种植。
To provide new wheat varieties with drought resistance,high yield and high quality for wheat production in Shanxi Province,to promote wheat variety update,and to achieve stable yield increase in wheat,by using Yunhan 20410 as the female parent and Yunhan 719 as the male parent,a new drought-resistant winter wheat variety Jinmai 105 was bred through ecological alternating selection between dryland and irrigated land,multi-environmental and multi-site identification,and pedigree analysis.Data from the regional experiment of dryland group in the mid-mature winter wheat region of southern Shanxi Province from 2017 to 2019 showed that average yield among 13 sites in 2 a was 4396.28 kg/ha which was 6.7%higher compared with that of the control variety Jinmai 47.Data from the production experiment of dryland group in the mid-mature winter wheat region of southern Shanxi Province from 2018 to 2019 showed that average yield among 7 sites was 4158.77 kg/ha which was 6.1%higher compared with that of the control variety Jinmai 47.The plant height,ear length,mature spike number,grain number per spike,and 1000-grain weight of this new variety were 73.6 cm,6.8 cm,4.8 million/ha,31.0 grains per ear,and 38.5 g,respectively.It is moderately susceptible to stripe rust,leaf rust and powdery mildew.This new variety is considered suitable for cultivation in the dryland of the southern wheat region in Shanxi Province,Huanghuai dryland wheat region,Weibei rain-fed plateau wheat region in Shaanxi Province,and other areas with similar ecological conditions.
