China Agric. Univ., Guangzhou 510642, China） Abstract：The paper approached the difference of the number of selected superior
family between the methods of performance level analysis and simple t-test,
under the condition of missing plots, missing trees and variance heterogeneity.
The accuracy of simple t-test was analyzed. It was put forward that family
selection can be carried out by combining performance level analysis and simple
t-test. Eleven superior families were selected from the 32 tested families and
the real gain for volume was estimated to be
35.8%. |
