To improve the hatchability of introduced,high yield chickens at Tibet altitude,and ameliorate the egg performance and reproduction traits of the local Tibetan chicken,four mating combinations between the Recessive White and Tibetan chicken were employed in this study.
为提高外来高产鸡品种在高原地区的种蛋孵化率,改良当地藏鸡的生产和繁殖性能,在西藏环境条件下以藏鸡和引进隐性白羽鸡为亲本设立4种交配组合,对其繁殖性状及影响因素进行了分析,结果表明:以藏鸡为母本的种蛋受精率显著低于隐性白羽鸡(P<0。
In this paper,the genetic evaluation of different mating combinations was done based on progeny test trails both at nursery and at young stage plantation.
本文通过对3个试点的49个鹅掌楸不同交配组合子代苗期生长、根系以及光合特性测定,2个试点的68个组合子代测定林2年生的生长量测定,通过统计及遗传分析,得出以下主要结论:鹅掌楸幼龄期生长量在地点间、组合间及组合内个体间差异极显著。
