当今香菇育种研究进展惊人,栽培的品种繁多。是育种家汇集自然界的香菇优良性状而培育出来的。这种优良性状是由单一式或几个遗传基因所支配,并在其后代中稳定继承。遗传基因物质几乎都存在于细胞核,当核分裂时,遗传因子聚集在一起,用显微镜可观察到如蜘蛛网状的染色体。然而,育种的任务之一在于怎样聚集更多具有优良性状的遗传基因,加以重新组合。香菇核分裂时期进行染色体重组,把遗传物质传给后代,是
The research on mushroom breeding is amazing nowadays, with a great variety of cultivars. It is bred by the breeder to bring together the excellent properties of mushrooms in nature. This fine trait is dominated by a single or a few genes and inherited steadily among its offspring. Almost all genetic material present in the nucleus, when the nuclear fission, genetic factors together, the microscope can be observed, such as cobweb chromosomes. However, one of the tasks of breeding is how to assemble more genes with excellent traits and recombine them. Mushroom nuclear division during chromosomal recombination, the genetic material passed on to future generations, is
