| Abstract: | Using completely randomized stock design,the genetic character of 200 families was determined,of half compatriot progeny of fine tree of Robinia pseudoacacia at seedling stage in three districts of Tianshui,Pingliang and Lonnan.The result indicated: there was extremely significant difference in height growth of various families and heritability was 62.35%;24 families had genetic gain and it reached 37.82%. |
