香豌豆（香豌豆L.）是日本主要的切花，通常在冬季至春季在温室中种植。野生型甜豌豆是一种长日照的夏季开花植物。日中性冬季开花能力，使切花生产在日本，是一个隐性表型，出现自发突变。虽然日本冬季开花的品种和春季开花的品种，其中有半长日开花能力产生的杂交冬季和夏季开花的品种，具有优良的切花表型，上级，他们有有限的颜色和香味的变化。特别是，杂色表型不出现在现代冬季和春季开花的品种，只有在夏季开花的品种。我们试图扩大日本切花品种的表型多样性。在此过程中，我们通过与夏花品种杂交，引入了杂色表型，并成功地选育了一些优良品种。在育种过程中，我们分析了分离比，揭示了表型的遗传规律。本文就这些杂色表型和冬花表型的遗传及其相关基因进行综述。我们还描述了我们如何将该性状引入冬季开花的品种，追踪它们的系谱，以显示每一代后代的表型和基因型。这一认识有助于有效地培育新的杂色品种。
Sweet pea (Lathyrus odoratus L.) is a major cut flower in Japan, generally grown in greenhouses in winter to spring. The wild-type sweet pea is a long-day summer-flowering plant. The day-neutral winter-flowering ability, which allows cut-flower production in Japan, is a recessive phenotype that emerged by spontaneous mutation. Although Japanese winter-flowering cultivars and additionally spring-flowering cultivars, which have semi-long-day flowering ability generated by crossing the winter- and summer-flowering cultivars, have superior phenotypes for cut flowers, they have limited variation in color and fragrance. In particular, variegated phenotypes do not appear in modern winter- and spring-flowering cultivars, only in summer-flowering cultivars. We try to expand the phenotypic diversity of Japanese cut flower cultivars. In the processes, we introduced the variegated phenotypes by crossing with summer-flowering cultivars, and succeeded in breeding some excellent cultivars. During breeding, we analyzed the segregation ratios and revealed the heredity of the phenotypes. Here we review the heredity of these variegated phenotypes and winter-flowering phenotypes and their related genes. We also describe how we introduced the trait into winter-flowering cultivars, tracing their pedigrees to show both phenotypes and genotypes of the progeny at each generation. This knowledge is useful for the efficient breeding of new variegated cultivars.
