Analysis and application of unbalanced data from crop culture experiment

Abstract

Abstract: With mixed linear model and MINQUE(1) method, the unbalanced data from crop culture experiment were analyzed, and the effect of ecological environment and its mutual effect with treatment combination on yield and other objective traits were revealed. The long term perplexed problem in analyzing unbalanced data from crop culture experiment was solved, and a new approach for estimating the stochastic effect of ecological environment was developed.

Key words: Culture experiment, Unbalanced data, Mixed linear model, MINQUE(1) method, young ear formation period, north japonica, influence, low temperature treatment, shell rate
