Summary TDZ (N-phenyl-N'-1, 2, 3-thidiazol-5-ylurea) is a substituted phenylurea compound
which was developed for mechanized harvesting of cotton bolls and has now emerged as a …

During the last fifteen years, flow cytometry and sorting greatly contributed to the
improvement of our knowledge of plant genome structure and function. This paper reviews …

Haploids and doubled haploids are very important in plant breeding, enabling the time
needed to produce homozygous lines to be shortened compared with conventional …

The bulb onion (Allium cepa L.) is grown on all continents except Antarctica, and is prized by
essentially all of the world's cultures for its flavor and health‐enhancing attributes. Both open …

Gynogenic haploid regeneration is an alternative procedure for haploid induction used in
several agronomically important species such as sugar-beet and onion. At inoculation …

An efficient in vitro multiplication system via multiple shoot bud induction and regeneration
has been developed in Chlorophytum arundinaceum using shoot crown explants. Optimum …

Long-day onion genotypes originating from Europe, North America and Japan were tested
for gynogenic induction ability. Haploid induction using an efficient single-step flower culture …

Unfertilized ovaries isolated from immature female flowers of coconut (Cocos nucifera L.)
were tested as a source of explants for callogenesis and somatic embryogenesis. The …

The use of doubled haploids in onion breeding is limited due to the low gynogenesis
efficiency of this species. Gynogenesis capacity from Spanish germplasm, including the …

The effects of polyamines on gynogenetic embryogenesis and regeneration of plantlets in
onion were studied. Whole flowers from two onion genotypes,'Valcatorce INTA'cultivar and …
