A method of pollen selection in seed-production nurseries of tetraploid beet

, : A method of pollen selection in seed-production nurseries of tetraploid beet. Biuletyn Instytutu Hodowli i Aklimatyzacji Roslin (142): 8

Microscopic examination of flowers taken, before they open, from the earliest flowering shoot of each bolting plant makes it possible to identify and eliminate all plants with pollen which fails to conform to tetraploid norms.
