A new method for estimating heritability of quantitative characters using a group of true-breeding genotypes was developed. This method applies to the experiment without replications and needs only the observations of the same group of genotypes in two environments such as years, locations or others. It is characteristic of simpler experiments,easier calculations and more actural estimates compared with the only method using a group of true-breeding genotypes——ANOVA (analysis of variance) .

本文提出了一种用纯合基因型估计数量性状遗传力的新方法。该法的试验不需设置重复,只要有若干纯合基因型在两种不同环境(如年份、地点或栽培措施)下的观测值即可,因此特别适合于作物品种资源研究或育种实践中的资料分析。文中用一个油菜实例对本法和现有唯一的用纯合基因型估计遗传力的方差分析法进行了比较,结果表明本法具有试验简单,计算容易和估值更为实际等优点。

A program for estimating the number of genes cotrolling a quantitative charactet was written inBASIC language,which based on Castle-Wrigbt formula and its modifications. The estimates and the standard er-rors are given by tbe program when the data (sample sizes,means,variances) of parents,F1 ,F2 ,backcrosses(B1 ,B2)are available The tests for fitness of additive-dominanee model are also done by Tan′s overall scaling test andsingle scaling tests.

Mammalisn surveys,focusing on wild ungulate species,were conducted in an unprotected region of central Qinghai province called Yeniugou during 1990~1992.Wild yak,Tibetan gazelle,Tibetan antelope,and blue sheep all numbered over 1000 during 1991;Tibetan wild ass numbered about 800,and argali about 250.Other mammalian were noted. Yeniugou is an important area for Qinghai-Tibetan plateau wildlife;probably one of the best remaining areas,particularly for wild yak and argali.Despite legal protection,poaching for most species is virtually uncontrolled.The most pressing need is to control poaching by non-residents.Establishing a nature reserve in Yeniugou is a possibility,but nearby experiences suggest that,failing funding mechanisms and an incentive scheme for local people to cooperate in wildlife protection,it would not be likely to succeed.Another possibility is to establish Yeniugou as a " wildlife management area".These concepts are discussed.

作者于1990~1992年在青海省中部未受保护的野牛沟地区进行以有蹄类物种为重点的野生动物考察。考察结果表明:藏羚羊、藏原羚、野牦牛和岩羊的数量都超过1000只,藏野驴约800只,盘羊近250只,白唇鹿未估计数量。对其他10种兽类也进行了考察。尽管有法律保护野生动物,但偷猎行为并没有得到控制。因此,必须尽快建立野牛沟自然保护区或野生动物管理区。
