Breeding Report onthe New Hulless Barley Line Longke 2 with Characteristics of Double High in Grain and Forage Production
摘要
Abstract
The development of suitable hulless barley variety provides strong support for the diversification and green development of the barley industry.Using Kunlun 3 as the female parent and Bai 4029 as the male parent,the Hulless Barley Research Group of the Institute of Economic Crops and Malting Barley,Gansu Academy of Agricultural Sciences,developed a hybrid combination and applied traditional breeding combined with modern biobreeding methods such as anther culture.After years of off-season generation advancement between southern and northern regions,a new high-grain-and-forage hulless barley line,Longke 2,was bred.Multi-year and multi-location regional experiments showed that Longke 2 had an average equivalent grain yield of 5 161.1 kg/ha,9.56%higher than the control variety Longqing 1.Its average biological yield during the filling stage reached 72 270.3 kg/ha,43.73%higher than the control Gansimai 1.The line exhibits excellent yield stability and high yield potential.Grain quality is superior,containing 127.7 g/kg crude protein,439.3 g/kg crude starch,and 28.3 g/kg ether extract,levels of amino acid,β-glucan,and polyphenol are significantly higher than those of common hulless barley and cereal forage.It is suitable for cultivation in hulless barley production areas at altitudes of 1 600 to 2 800 m asl.关键词
