优质酿造糯高粱新品种晋糯4号选育报告OA

To breed glutinous sorghum varieties suitable for cultivation in northern China,the Sorghum Research Institute of Shanxi Agricultural University developed target parental lines by pyramiding multiple elite traits through germplasm collection and in-novation,and successfully bred a new high-quality glutinous sorghum variety Jinnuo 4 by using its self-developed male-sterile line 11476A as the female parent and self-developed restorer line L2R as the male parent.In the national regional experiment of glutinous sorghum varieties from 2013 to 2014,Jinnuo 4 achieved an average equivalent yield of 6 575.6 kg/ha,representing a 12.5%increase over the control variety and a 6.9%increase compared to the average yield of all tested varieties.In the 2015 national production ex-periment of glutinous sorghum varieties,Jinnuo 4 achieved an average equivalent yield of 6 355.5 kg/ha,representing a 12.7%in-crease over the control variety Chuannuoliang 15.Jinnuo 4 has a growth period of 116 days,plant height of 173.2 cm,panicle length of 31.4 cm,grain weight per panicle of 65.9 g,and a 1000-grain weight of 23.1 g.The grains contain 79.4 g/kg crude protein,747.4 g/kg crude starch(among which amylopectin accounts for as high as 99.5%),13.0 g/kg tannin,and 36.2 g/kg ether extract.Jinnuo 4 exhibits strong seedling emergence,wide adaptability,high yield potential,and high amylopectin content.It is an excellent glutinoussorghum variety suitable for brewing and well-adapted to large-scale cultivation in northern regions of China.
