On the basis of the relationship between heritabilityandregression coefficient,the error analysis of theoretically assessed mean Y of fillal generation has been carried out.The results show that heritability is a population concept and not fit for estimatng the genetic advance of individuals, and when heritability or selection differential is at a low level,the reliability of expected genetic advance is even worse;and that while the genetic advance of a small colony is assessed with heritability,the estimailve value will rise greatly.As long as the selected sample number is large enough the assessment error of expected genetic advance can be reduced to an allowable limit. 从遗传力与回归系数的关系入手．通过对亲子回归中子代平均数理论估计值Ｙ的误差进行分析，结果表明：遗传力是一个群体概念，不适合估算个体的遗传进度．特别是在遗传力较低或选择差较小时，个体的遗传进度估计值的可靠性更差；用遗传力估算由多个个体组成的小群体的遗传进度时，其遗传进度估计值的可靠性将大大提高．只要入选样本容量足够大．其遗传进度估计值的误差估计可以降低到允许的范围． This paper establishes the schedule risk analysis model of network planning. Based on the simulation method, schedule estimate and statistical distribution of projects are given, then the risk distribution of total period is obtained.
