一个高产类型的品种在推广以前,需经过几年的多点大区试验。用这样一些区域试验来验证某一品种的最适应用环境。尼日利亚农业研究所在本国热带大草原的四个不同生态区域中进行了新育成高粱栽培种(品种)的正规鉴定。这些地区与高粱的四个熟期相一致。本文的目的是:1)确定在推广新改良的高粱品种以前的试验程序是否适宜;2)估算所利用高粱品种的稳定性参数和适应性参数;3)评价
A variety of high-yielding varieties in the promotion of the past, after several years of multi-point regional trial. Use some of these regional tests to verify the optimum application environment for a particular species. The Nigerian Institute of Agriculture conducted a formal identification of newly bred sorghum cultivars (cultivars) in four different ecoregions of the country’s own savanna. These areas are consistent with the four maturing dates of sorghum. The purpose of this paper is to: 1) determine the appropriateness of the testing procedures prior to the promotion of a new improved sorghum variety; 2) estimate the stability and fitness parameters of the sorghum varieties used; and 3)
