抗旱节水高产稳产小麦新品种‘济儒麦25’的选育及性状分析

The New Wheat Variety‘Jirumai 25’with Drought Resistance,Water Saving,High and Stable Yield:Breeding and Characteristic Analysis

为了培育干旱年份稳产、丰水年份高产的小麦新品种,济宁市农业科学研究院通过有性杂交系统选育,以‘山农2149’为母本,以‘良星619’为父本,成功培育出了小麦新品种‘济儒麦25’。该品种属冬性,株高77.5 cm,株型紧凑,具有抗倒性好,熟相好,籽粒饱满,商品性好,抗旱节水,高产稳产,综合抗性好等特点。2年区域试验结果平均产量为7742.55 kg/hm^(2),比对照增产4.02%。在2022—2023年山东省小麦旱地生产试验中,平均产量为7176.15 kg/hm^(2),比对照‘山农27’增产5.60%,增产点率100%。2023年12月通过山东省农作物品种审定委员会审定,审定编号为鲁审麦20230029。‘济儒麦25’小麦新品种的审定,为鲁西南旱地小麦生产提供了品种支撑,并展现出广阔的推广应用前景。

In order to cultivate new wheat varieties with stable yield in dry years and high yield in wet years,a new wheat variety‘Jirumai 25’was bred by Jining Academy of Agricultural Sciences.This variety was developed through sexual hybridization using the high-yield and drought resistant variety‘Shannong 2149’as the female parent and the high-yield variety‘Liangxing 619’as the male parent.‘Jirumai 25’is the winter type with a plant height of 77.5 cm,good lodging resistance and ripening,full grain,good commodity,drought resistance,water saving,high and stable yield,and good integrated resistance.The results of the two-year regional experiments showed that the average yield was 7742.55 kg/hm^(2),which was 4.02% higher than that of the control variety.In the production experiment of Shandong wheat dryland in 2022-2023,the average yield was 7176.15 kg/hm^(2),which increased by 5.6% compared with‘Shannong 27’,and the yield increase rate was 100%.It was approved by the Shandong Crop Variety Approval Committee in December 2023,with the approval number of Lu Sheng Mai 20230029.The approval of'Jirumai 25'wheat new variety provides strong breed support for dryland wheat production in southwestern Shandong and has a broad application prospects.
