The use of genetic, manual and chemical methods to control pollination in vegetable seed production : a review
(Wiley Blackwell Publishing, Inc, 2017-06)
Production of hybrid varieties of vegetable crops is currently a desired breeding goal, due to their remarkable agronomic performance and to the possibility of intellectual property protection. However, efficient hybrid ...

Apospory followed by sterility in a hypotriploid hybrid (2x X 4x) of Paspalum
(Univ Florence Botany Inst, 2004-12)
A self-incompatible diploid plant (2n = 2x = 20) of Paspalum limbatum grown in a field nursery surrounded by tetraploid accessions of several Paspalum species produced a hypotriploid descendant (2n-1 = 3x = 29). Molecular ...
Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
(Sociedade Botânica do Brasil, 2019-09-01)
ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages ...

Pollen-mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense bitter under experimental field conditions in argentina
(Wiley Blackwell Publishing, Inc, 2013-12-10)
The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber-bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ...
