摘　　要：异源八倍体小黑麦劲松81于2006年通过贵州省农作物品种审定委员会审定。该品种具有矮秆、高产、稳产、易脱粒、结实率高、饱满度好，营养品质优异，对白粉病免疫，适应性广，再生能力强，可在早春割苗作饲料，粮饲兼用等优点。在中等、中下等肥力旱地中其区域试验平均产量226．14～251．6kg／667m^2，比劲松49（CK）增产12．84％～16．63％，居参试品种之首。生产试验平均产量258．5kg／667m^2，最高产量达348kg／667m^2，比CK增产17．66％，适宜在贵州海拔为1000～2300m的高寒山区、半山区，中部麦区的中、下等肥力旱地以及省外生态环境近似的地区种植。Jingsong 81 was released by Guizhou Crop Variety Committee in 2006.The variety has the advantages of dwarf type,high-stable yield,easy threshing,higher seed setting rate,good full seed,high quality,immune powdery mildew,better adaptive faculty,strong regrowth ability and food-fodder dual-purpose.The average yield was 226.14～251.6 kg/667m2 in the upland fields with middle or middle-lower fertility in the regional test,12.84%～16.63% higher than CK(Jingsong 49).The average yield in the production tests was 258.5 kg/667m2,17.66% higher than CK and the highest yield could be up to 348 kg/667m2.Jingsong 81 can be planted in the upland fields with the middle or middle-lower fertility in the mountain and semi-mountain areas with an elevation of 1000～2300 meters and other similar ecological condition areas.
