Haploidy and mutation techniques FAO/IAEA Mutant Varieties Database now lists almost 1800 officially released mutant cultivars in more than 150 plant species (Maluszynski .,1991, 1992). Mutant cultivars or mutated genes have significantly contributed to the economy of many countries. One example is X-ray induced semidwarfness in t

Molecular and biochemical events during the induction of microspore embryogenesister meiosis with two types of haploid gametophytes or spores: microspores, which develop into pollen grains within the anther (male gametogenesis), and megaspores, which form the embryo sac within the ovule (female gametogenesis). During male gametogenesis microspores undergo a precisely defined and

The utility of doubled haploid populations for studying the genetic control of traits determinated b doubled haploids can be obtained by utilizing interspecific crossing and embryo rescue (Kasha and Kao, 1970; Jensen, 1977; Pickering and Devaux, 1992) or tissue cultures of gametic cells (Herberle-Bors, 1985; Foroughi-Wehr and Wenzel, 1988). The reduction in the time required to obtain homozygous l

Influence of ethylene in microspore embryogenesish, development and senescence and its effects are commercially important (Yang and Hoffman, 1984). Some of the physiological processes influenced by ethylene are release of seed, bud dormancy, seedling etiolation, seedling and stem growth, flower and fruit initiation, fruit growth and ripening and p

Microspore cultured in Pteridophytes (Fernandez ..,1993). This parallel has been drawn in a number of reviews (Dunwell, 1978, 1992) and although the detail will not be repeated here, it is worth drawing attention again to one of these earlier studies in which Hirsch (1975) showed a definite nutritional role of sucros
