莲属(Nelumbo)植物全球共有两种,它们的地理分布距离很远。其中 N.Iutea分布在北美到南美的哥伦比亚,而N.nucifera则分布在东亚到大洋洲东北部,两者在分布上是被太平洋所隔离的。这两个种在形态上有所差异,但以花色和花型的差别最为显著。前者体态较小,花亦较小且为单瓣花型,花黄色,少有其它颜色。后者的体态大,花大色艳,有很多半重瓣和重瓣、重台品种,花色有红、白、粉等,唯独缺少黄花类型。 据我们近两年的观察,这两个种之间的有性杂交很易成功。据不完全统计,以N.nucifera为母本, N.lutea作父本的27个杂交组合平均结实率为60.9％,反交的7个
There are two types of Nelumbo plants worldwide, and their geographical distribution is far apart. N. Iutea is distributed in North America to South America in Colombia, while N.nucifera is distributed in East Asia to the northeast of Oceania, both of which are distributed by the Pacific Ocean. The two species vary in morphology, but the difference between flower color and pattern is the most significant. The former body is smaller, the flowers are smaller and single-flower, yellow, few other colors. The latter’s body is large, large flower color, there are many semi-double and double petals, re-Taiwan varieties, red, white, pink, etc., except the lack of yellow type. According to our observations in the past two years, it is very easy to have sexual cross-breeding between the two species. According to incomplete statistics, the average seed-setting rate of N. napus as the female parent and N.lutea’s father’s 27 cross combinations was 60.9% and 7
