现代月季多数为不同类型及品种之间反复杂交育成的,无论是自花还是异花授粉,通过基因重组,出现新类型的机率都很大。其中自然杂交早已被人们用来作为培育月季新品种的一个重要手段。切花月季新品种“傲雪”,即是我们从“圣诞积雪”的自然杂交后代中选育出的佼佼者。一、选育经过 1989年底,我们从本所月季母本园中采集到一批自然杂交种子,经砂藏越冬,于1990年春播种,得到实生苗272株。分别盆栽观察,发现“圣诞积雪”自然杂交后代中有一株花枝挺拔而长,光滑近乎无刺,花朵较母本小而紧凑,花色变得洁白,花瓣质厚耐开。根据上述特性,我们认为此花非常适宜作切花。1991年将这株花移入大盆栽培,并施足底肥,作为原始母本重点观察,同时采用嫁接和扦插法进行小批量繁殖,详细观察后代多种性状表现,并与母本进行比较。经两年观察,其后代性状表现与母本一致,十分稳定。1993～1994年我们
Most of the modern rose for different types and breeds repeatedly cross-breeding, both self-pollinated or cross-pollination, through gene recombination, there is a great chance of a new type. Among them, natural hybridization has long been used as an important means to cultivate new varieties of roses. A new species of cut rose “Aoxue”, that is, we from the “Christmas snow” natural breeding offspring among the best. I. BREEDING After the end of 1989, we collected a batch of natural hybrid seeds from the mother garden of our institute. After the sand was stored in the winter, we sown it in the spring of 1990 and got 272 seedlings. Potted plants were observed, and found that “Christmas snow” natural hybrid progenies in a straight and long and smooth, almost no thorns, flowers than the mother of small and compact, white flowers, petals thick-resistant. Based on the above characteristics, we think this flower is very suitable for cut flowers. In 1991, this flower was transferred to a large pot culture, and applied enough plant fat, as the original mother of the key observation, at the same time using grafting and cutting method for small batch reproduction, a detailed observation of the offspring of a variety of traits, and compared with the female parent. After two years of observation, the performance of their offspring consistent with the mother, very stable. 1993 ~ 1994 us
