| 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。

| Abstract: | 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 P×F was 8223.15 kg/hm2,which was 18% to 40% higher than that of their parents.The crude protein content of Y×P 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. |
