Abstract

Haploid plants have the gametophytic number of chromosomes, that is a single set of chromosomes in the sporophyte. Their significance for plant improvement, and as a tool in various disciplines of plant science has been stressed (see Kasha, 1974 a). Since haploids are of great importance, especially in studies on the induction of mutations and also for the production of homozygous plants, they are needed in large numbers. However, the conventional methods (Kimber and Riley, 1963; Magoon and Khanna, 1963), employed by plant breeders for their production are cumbersome, laborious and not very efficient. With the introduction of techniques for the induction of androgenesis by the culture of excised anthers (Guha and Maheshwari, 1964), isolated pollen (Nitsch, 1974a) and by chromosome elimination through hybrid embryo culture (Kasha and Kao, 1970) it has become increasingly evident that tissue culture methods could considerably speed up the production of haploids for breeding programs. These topics are dealt with in detail in the subsequent articles in this chapter.
