油菜优树选择是根据表型进行,表型是基因与环境共同作用的结果,往往因环境的变化而变化,因而从表型选择的优树其性状能否传给后代,传递的能力有多大是无法在表型选择中作出判断。为了解表型选择中优树的遗传传递能力,获得性状较好的优 Younger tree selection is based on the phenotype, the phenotype is the result of genes and the environment together, often due to environmental changes and changes, and therefore from the phenotypic selection tree its traits can be passed on to future generations, the ability to pass how much It is impossible to make a judgment in phenotyping. In order to understand the phenotypic selection superior tree genetic transfer ability, get good character better
