Abstract
Brassica rapa is recognized originally as a turnip (Prakash and Hinata, 1980). However, root and aerial parts of this plant have a wide morphological diversity especially in germplasm in East Asia.
For example, Mizuna, a local vegetable in Kyoto, Japan, is characterized in its extensive branching and very thin petioles.
Various types of heading Chinese cabbage are known (Li, 1983). Radish (Raphanus sativus) also has a wide morphological diversity (Kitamura, 1958; Kaneko et al., 2007). Root of this crop varied from tiny European small radishes to huge root (up to 20 kg) of Sakurajima radish.
Moriguchi radish is known to produce the longest root in radish.
The root of this radish is up to 120 cm long (Matsubara, 1994). Rat-tailed radish or podding radish, which is cultivated in Tropical Asia, flowers without vernalization and produces long pods.
Mapping and molecular cloning of the genes controlling these various traits is one of the major targets in Brassica genetic study.
