摘　　要：研究了杂种披碱草-圆柱披碱草×披碱草（简称Y×P）和披碱草×肥披碱草（简称P×F）及亲本-披碱草，肥披碱草和圆柱披碱草的产量和品质特性。结果表明：Y×P的干草产量为9168．75kg／hm2，比亲本提高46．8％～52．0％，P×F的干草产量为8223．15kg／hm2，比亲本提高18．3～40．7％；两个杂种披碱草叶量较为丰富，茎叶比均显著低于母本。杂种Y×P的营养成分均不同程度的高于其亲本。杂种披碱草在产量和品质特性方面均表现出较高的杂种优势，其中Y×P的杂种优势高于P×F。The yields and quality of two hybrids, including Elyrnus cylindricus× E. dahuricus （Y×P） and E. dahuricus×E, excelsus （P×F）, and their parents were studied. The results indicated that the yields and crude protein contents of the hybrids were higher than their parents. Hay yield of Y×P was 9168. 75 kg/hm2, which was 47% to 52% higher than that of their parents. Hay yield of PX F was 8223.15 kg/hm2, which was 18% to 40% higher than that of their parents. The crude protein content of YXP was 14. 01%, which was 0.23% to 1.47% higher than its parents. The two hybrids were better than their parents in yields and quality characters, and the heterosis of Y×P was significantly better than P×F.
