The New Wheat Variety'Jirumai 25'with Drought Resistance,Water Saving,High and Stable Yield:Breeding and Characteristic Analysis
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/hm2,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/hm2,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.
