随着农业生产的发展和科学技术的进步,对杂交种除了要求高产外,越来越注意其稳产性。目前,一般采用联合区域试验的方法来测定杂交种的稳定性。虽然在区域试验中各试验点均采用统一的试验方案,试验设计和试验方法也都合乎统计分析的要求,但实际上对区试资料的分析仅仅是从各试验 With the development of agricultural production and the progress of science and technology, in addition to demanding high yield hybrids, more and more attention to its stability. At present, the stability of hybrids is generally determined by the method of joint regional test. Although all experimental sites in the regional test using a unified test protocol, test design and test methods are also in line with the requirements of statistical analysis, but in fact the analysis of regional test data only from the test
