Abstract：Esimai 438 is a new silage barley variety developed by Institute of Food Crops of Hubei Academy of Agricultural Sciences through targeted pedigree selection from the cross"E 32380//Edamai No.6//Edamai 934".Esimai 438 is a spring-type two-row barley variety with strong stem,strong tillering ability,high spike formation rate,strong comprehensive stress resistance and outstanding resistance to lodging.According to the multi-point joint evaluation trial of barley of Hubei Province from 2016 to 2018,the average grain yield of Esimai 438 was 384.86 kg/667 m2 in the two years,which was 8.71%higher than that of the variety HuaDamai No.9(CK).The average total growth period of Esimai 438 was 173.7 days,which was 1.7 days later than that of CK.The plant height was 81.10 cm,the number of spikes was 395 300 per 667 m2,the number of grains per spike was 24.00,and the thousand-grain weight was 41.62 g;the protein content of the grains(mass fraction)was 12.13%,the starch content was 52.85%,the lysine content was 0.44%,and the β-glucan content was 6.92%.According to the multi-point joint evaluation trial of silage barley of Hubei Province from 2020 to 2022,the dry matter yield of Esimai 438 was 975.90 kg/667 m2,which was 9.97%higher than that of the CK.To fully utilize Esimai 438 in barley silage production in Hubei Province and adjacent areas,the present article provides a detailed introduction to the parental characteristics,breeding process,characteristics and high-yield cultivation techniques of this variety,with the aim of providing technical support for its large-scale application in production.
