作物的产质量,不仅受土壤条件、栽培条件、自然条件的影响,而且也受品种的适应性制约,即主要是由于作物基因型和环境条件互作所造成。但是,如何确定品种的适应性,找出明确的指标,还是一个较为复杂的问题。 多年来,我国在进行甜菜新品种(系)区域试验中,一直沿用简单的百分比法,近年才开始用t测验的方法进行品种的显著性测定,但在科学飞跃发展的今天,还远远不足,应尽早启用较先进的即用“稳定性参数”来测定甜菜新品种的稳定性,以便在统计分析上,提高品种区域比较试验的科学性和准确性。 Crop production and quality, not only by the soil conditions, cultivation conditions, natural conditions, but also by the species adaptability constraints, mainly due to crop genotype and environmental conditions caused by interaction. However, how to determine the adaptability of varieties and find a clear indicator is still a more complicated issue. Over the years, China has been using a simple percentage method in the field trials of new varieties of sugar beet. In recent years, the t test has been used to measure the significance of varieties. However, in the rapid development of science, it is still far from enough , The more advanced out-of-the-box “stability parameters” should be enabled as soon as possible to determine the stability of the new sugar beet varieties in order to improve the scientificity and accuracy of the comparative testing of varieties in the statistical analysis.
