Notes
Small plants of Chinese Kale grown in crowded conditions
The cultivated species of the genus Brassica (about 40 species of annual and biennial herbs) are important in horticulture. The Brassica group is a most perplexing and bewildering family of crops, not only because of the frequency of outcrossing that often results in viable hybrids, but also the relative ease with which new mutants can be selected and new cultivars developed. Pearson (1929) was the first to suggest classifying Brassica on the basis of chromosome numbers. V.G. Sun summarized it as three elementary species comprising B. Campestris L. (n=10), B. Nigra Koch (n=8) and B. Oleracea L. (n=9) and all the other species are derived from them.
