Triploid flowering pears reduce self-sowing

20:00 EDT 18 Oct 2016 | AAAS

(American Society for Horticultural Science) In analyses of 13 flowering pear triploids, relative female fertility was significantly reduced, ranging from 0.0% to 33.6%. Five accessions had a relative fertility of <2%. Cytometric analysis of seeds and seedlings from triploid maternal parents showed that they were predominantly abnormal aneuploids, typically resulting in seedlings with reduced fitness and fertility. The results indicate that selection of infertile cultivars can be a viable approach to reducing unwanted reseeding in flowering pear.
