在作物新品种选育中,产量是选择的主要指标。为了提高对产量选择的精确性。我们可以在广泛试验的基础上,将历年积累的试验资料加以整理,抓住重复多次的现象间的偶然性进行深入研究,从中推导出必然性的规律。经过数理统计,对作物产量与其主要经济性状之间的关系用“数”来表示,建立适宜的数学模型,提出选择指教,以此为今后综合评判入选个体或品系的优劣,提高选择效果,加快新品种选育的进程。
In the breeding of new varieties of crops, the yield is the main indicator of choice. In order to improve the accuracy of the choice of production. Based on a wide range of experiments, we can sort out the experimental data accumulated over the years and grasp the contingency between phenomena repeated many times to derive the law of necessity. Through mathematical statistics, the relationship between crop yield and its main economic traits is represented by “number”, the appropriate mathematical model is established, and the suggestion of choice is given. In this way, the advantages and disadvantages of selected individuals or strains and the selection effect are comprehensively evaluated in the future, Speed up the process of breeding new varieties.
