鉴于现代月季多数为不同类型及品种之间反复杂交育成,无论是同花还是异花授粉,通过基因重组,出现新类型的机率甚大,自然杂交早被人们用来作为培育月季新品种的一个重要手段。实践证明,通过自然杂交可望选育出高质量的优秀月季新品种。国内的“大绿洲”及我市“龙城秋色”、“新牡丹”等新种均通过自然杂交选育而成。笔者从多年自然杂交育种实践中,在花色、花型、花径、香味等方面初步 In view of the majority of modern rose for the different types and breeds of crossbreeding between, whether it is flush or cross pollination, through gene recombination, a new type of probability is very large, natural hybrids have long been used as a breeding new varieties of roses is important means. Practice has proved that through natural crossbreeding is expected to breed high-quality new varieties of rose. The domestic “Big Oasis” and our city “Longcheng autumn color”, “New Peony” and other new species are bred by natural breeding. The author from years of natural hybrid breeding practice, in the color, flower type, flower diameter, flavor and other aspects of the initial
