The genus Petunia was first established in 1803 and since then, 30 Petunia species have been described, originated from South America (Sink, 1984). Because of inconsistency in taxonomic data of different Petunia species, the exact origin of the cultivated Petunia hybrida (Fig. 1) is still unknown. Van der Krol & Chua (1993) speculated that P.

Citrus fruits are cultivated in more than 80 countries and rank first among fruit crops for worldwide production with about 73 millions tons harvested annually (FAO, 1994). Citrus fruits are an important source of human nutrition. Due to lower production costs, the cultivation of Citrus in developing countries has increased from 50 to 65% of total ...

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.

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.

The main objective of this chapter is to review research on experimental induction of haploids in tree species since the pioneering efforts of LaRue and coworkers in the late fifties. Initially, however, we shall discuss some features of trees affecting haploid research, and give a brief outline of male and female gametophyte development in vivo, to ...

The most effective medium to sustain pollen growth and development (Fig. 1) was Murashige and Skoog (1962) inorganic salt solution with a modified vitamin amino acid solution (meso-inositol 100mg/l; glycine 2mg/l; thiamine HCl 0.5 mg/1; nicotinic acid 5.0 mg/1; pyridoxine HCl 0.5 mg/1; folic aid 0.5 mg/1; biotin 0.05 mg/1).

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 ...
