Summary
Chinese cabbage (Brassica campestris pekinensis) is originated from China. However, its wild form has not been found. Its primary cultivated form (A), a loose-leaf variety (var dissoluta Li) was first recorded in Chinese literature in the 5th century, and was probably produced by natural crossing between pak-choi (ssp chinensis (L) Makino) and turnip (ssp rapifera (Metzy)). By developing the head forming habit, it evolved successively to (B), a semi-heading variety (var infarcta Li), (C), a fluffy-topped heading variety (var laxa Tsen et Lee) and then (D), a heading variety (var cephalata Tsen et Lee). There are three morphotypes of the last, which have developed in different climatic areas, each adapting to different ecological conditions and having different head shape. These are : (D1) oval form (f ovata Li); (D2) flat-topped form (f depressa Li); and (D3) cylindrical form (f cylindrica Li). By crossing these varieties and forms, five hybrid forms were developed in the past. These are fluffy-topped oval (C x D1), fluffy-topped cylindrical (C x D3), flat-topped oval (D1 x D2), stout-cylindrical (D1 x D3) and flat-topped cylindrical (D2 x D3). In 198 cross combinations the average heterosis percentages on the basis of yield were significantly different in combinations differing in parental interrelationships: crosses within the same variety or form -10.16 plus or minus 2.47%; those between different varieties or form -20.44 plus or minus 2.19%; those between variety and hybrid form -26.24 plus or minus 3.22; and those between different hybrid forms -44.22 plus or minus 8.42. Therefore, crossing different varieties or forms, especially different hybrid forms, is promising for obtaining heterosis of yield. [AS]
