Karyotypic variation and pollen stainability in resynthesized allopolyploids Tragopogon miscellus and T. mirus [PDF]
American Journal of Botany, 2017 PREMISE OF THE STUDY:Polyploidy has extensively shaped the evolution of plants, but the early stages of polyploidy are still poorly understood. The neoallopolyploid species Tragopogon mirus and T. miscellus are both characterized by widespread karyotypic variation, including frequent aneuploidy and intergenomic translocations. Our study illuminates the

Cytology, pollen stainability and yield in desynaptic autotetraploid Capsicum.
CYTOLOGIA, 1984 Autotetraploidy was induced in the genus Capsicum annuum L., an economically important spice crop of considerable local importance. A few plants produced wrinkled fruits in the first generation with very few seeds in them and turned out to be desynaptic autotetraploid plants after cytological analysis.

Hybridization in Four Nigerian Physalis (Linn.) Species
Notulae Scientia Biologicae, 2018 Interspecific reciprocal crosses among four Nigerian Physalis species (Physalis angulata, P. micrantha, P. pubescens and P. peruviana) were carried out by transferring desired pollen grains to ovalate parents, bagged and labelled to prevent contamination

Variable Penetrance among Different Sources of the Male Fertility Restoration Allele of Onion
HortScience, 2020 Hybrid onion (Allium cepa) seed is produced using cytoplasmic male sterility (CMS). For the most commonly used source of onion CMS, male fertile plants possess male sterile (S) cytoplasm and dominant allele(s) at one nuclear male fertility locus (Ms ...
