Abstract
While onion (Allium cepa L.) plants have significantly different morphologies in height, leaves, scape, and inflorescence, their bulbs differ in pungency, color, size, firmness, shape, tightness of bulb scales and neck. As in other vegetables, resistance to diseases, better quality, high yield, and uniformity are the major breeding achievements in onion. However, being a biennial plant with alternative seed-to-bulb and bulb-to-seed generations, the genetic progression of any desired trait in onion is relatively slow. This chapter reviews general breeding objectives, genetics and morphological markers found in seed, seedling, leaf, scape, bulb scale, and flower, genetics of some biotic and abiotic stresses, and cautions for marker-assisted selection to develop maintainer lines.
