摘要
辽宁绒山羊与巴仑台山羊的级进杂交试验结果表明,杂交效果显著:F1、F2、F3代产绒量和绒长度均极显著高于巴仑台山羊(P<0.01),产绒量分别提高了1.61倍、2.63倍、2.84倍,绒长度分别提高27%、63%和72%,绒纤维直径随着产绒量的提高而增粗,分别比巴仑台山羊增粗了1.45、1.95和3.40um,差异极显著(P<0.01),但没有超过16μm,仍属于优质绒范围。
The upgrading shows that, through hybridization with Liaoning Cashmere, the improvement to Baluntai Goat is remarkable. The production of fine hair in terms of quantity and hair length of generation F1, F2 and F3 are notably greater （P〈 0.01） than that of the Baluntai Goat, with production volume increasing by 27%, 63 % and 72% respectively, and slightly diametrical fiber thickening.
