Abstract The aims of this study were to determine the meiotic behavior and to estimate pollen grains viability in bean (Phaseolus vulgaris L.) cultivars. Flower buds were collected during different developmental stages
of the Mesoamerican bean cultivars IAPAR 44, Guapo Brilhante, BRS Expedito, BRS Valente, Guateian 6662
and Pérola, and the Andean bean cultivar Iraí, grown in a greenhouse. The meiotic index was determined by
anther squashing of material fixed in absolute ethanol-glacial acetic acid (3:1) and stained with acetic orcein.
No meiotic abnormalities were observed and the meiotic indices were high for all cultivars, indicating that the
mismatch generated during… More >
