Abstract:Crosses were made between 2X and 4X red clover (Trifolium pratense L.) plants under field cages by honey bees (Apis mellifera L.) to investigate the feasibility of producing autotetraploids by the mechanism of unreduced gametes. Clones from three cultivars and one experimental strain were used as female parents (diploids) and plants from a nitrous oxide‐derived tetraploid population of the cultivar ‘Kenstar’ were used as the male parents. Diploid parents yielding low amounts of seed produced a high percentage … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
