月季育种,除杂交育种外,还可以利用芽变来培育新品种。芽变育种不需要通过有性杂交,便可以获得新的花色、花形、树姿等优良性状。月季的体细胞,在自然界由于受到外部各种因素(如光照、温度、射线和化学物质等)的影响,其体细胞内的遗传因子染色体诱发畸变或基因突变,改变原有性状,引起芽变。在自然界这种芽变的机会虽然每年在月季的生长季节都会发生,但往往由于没有发现而把它修剪掉或自然消失,失去了获得新品种的机会。在月季盛开的季节, Rose breeding, in addition to hybrid breeding, you can also use the bud to cultivate new varieties. Bud mutation breeding do not need sexual cross, you can get a new flower color, flower shape, tree posture and other fine traits. Rose in somatic cells, in nature due to external factors (such as light, temperature, radiation and chemical substances, etc.), the somatic cells within the genetic chromosome induced aberrations or gene mutations, change the original traits, causing the bud . In spite of this opportunity to change buds in nature every year during the growing season of roses will occur, but often undetected because of its disappear or disappear naturally lost the opportunity to obtain new varieties. In the season in full bloom,
