Abstract A haploid is an organism that looks like a sporophyte, but has the chromosome complement of a reduced gamete. There are several ways in which haploids can occur or be induced in vivo: spontaneously, mostly associated with polyembryony, and through abnormal processes after crosses, like pseudogamy, semigamy, preferential ...

The coexistence of haploidy and diploidy in yeasts
Experientia, 1959In einigen Hefearten kommen haploide und diploide Zellen zusammen vor. Es wird angenommen, dass diese Koexistenz besondere Vorteile fur die Anpassung der Hefe an Milieux mit schnell wechselnden Bedingungen bietet. Die Vorteile der Haploidie und Diploidie erganzen sich, ohne dass sich die Nachteile der einen oder andern Form auswirken.

Haploidy and mutation techniques
1996Mutation techniques have already proven their potential for generating useful variability for plant breeding (Micke et al.,1990; Sigurbjornsson, 1983). The FAO/IAEA Mutant Varieties Database now lists almost 1800 officially released mutant cultivars in more than 150 plant species (Maluszynski et al.,1991, 1992).

Triticale Triticosecale (Wittmack), often called the first man-made cereal, is a cross between wheat (Triticum) and rye (Secale cereale). Depending on the ploidy level triticales can be divided into three main groups: 1. Tetraploids: crosses between diploid wheat and rye; 2.

Solanum melongena L. (2n = 2x = 24) is also known as eggplant, aubergine, brinjal or Guinea squash. This species is probably a native of Asia; the Indo-Burma Asiatic region, China and Japan are considered the centers of origin. It has been cultivated in Asia from the 5th century, and was introduced to Europe by the Arabs during the dark ages (Khan ...

The genus Nicotiana belongs to the tribe of Nicotianeae, of the family Solanaceae. It was classified by Goodspeed (1954) into three subgenera (Rustica, Tabacum and Petunioides), 14 sections and 60 species. Forty-five are indigenous to North and South America and 15, the Suaveolentes section of the subgenus Petunioides, to Australia. Five new species (N.
