Breeding Report on the New Functional Hulless Barley Variety Longke 1
摘要
Abstract
In order to cultivate the functional hulless barley varieties that meet the market requirement,a new variety named Longke 1 was developed by hybridizing the local variety Heshang hulless as the female parent and the hulless barley variety Longqing 1 as the male parent,using a combination of traditional and modern biological breeding methods.From 2021 to 2023,it participated in multi-location regional experiment across Gansu Province,showing an average yield of 5 027.4 kg/ha across 15 site over 3 years,which was 7.29%higher than the control variety Longqing 1.In the 2023 production experiment for hulless barley lines in Gansu,it achieved an average yield of 5 098.3 kg/ha,an 8.19%increase over the control,demonstrating strong yield stability and high productivity.Longke 1 is of spring nature with a growth period of 105 to 110 days,and it is of the medium-maturing type.The grain contains 139.2 g/kg crude protein,654.5 g/kg crude starch,19.6 g/kg ether extract,3.9 g/kg lysine,62.5 g/kg total amino acids,20.1 g/kg ash,558.8 g/kg branched starch,65.9 g/kg β-glucan,and 43.87 ug/g polyphenol.It is suitable for cultivation in hulless barley planting areas with an altitude of 1 700 to 3 000 m.关键词
