三我国生产原种的方法是综合应用系谱选择和混合选择的改良混合选择法,即建立穗(株)行圃以严格选择;建立穗(株)系圃以分系比较;建立原种圃以混系繁殖。这种方法便于结合品种表现型的观察,比较深入进行基因型的分析研究,可以通过穗行、株行
Third, China’s production of the original species method is the comprehensive application of pedigree selection and mixed selection of improved hybrid selection method, namely the establishment of spikes (plant) nurseries to strict selection; establishment of spikes (strains) Department of nurseries to the Department of comparison; the establishment of the original nursery Mixed breeding. This method is easy to combine the observation of species phenotype, more in-depth analysis of genotypes, by ear lines, plant line
