Chromosome numbers in Czechoslovak species ofGagea (Liliaceae)

Chromosome numbers are reported for the following Czechoslovak representatives of the genusGagea Salisb.:G. bohemica (Zauschn.) J. A. etJ. H. Schult. subsp.bohemica (2n=60),G. lutea (L.)Ker-Gawl. (2n=72),G. minima (L.)Ker-Gawl. (2n=24),G. cf.paczoskii (Zapal.) Grossh. (2n=48),G. cf.pomeranica Ruthe (2n=48),G. pratensis (Pers.) Dum. s. str. (2n=60),G. pusilla (F. W. Schmidt) J. A. etJ. H. Schult. (2n=24),G. spathacea (Hayne) Salisb. (2n=106), andG. villosa (M. Bieb.) Duby (2n=48). Meiotic behavior was found to be essentially regular inG. pusilla andG. villosa whereas a high proportion of meiotic irregularities was noted inG. bohemica andG. pratensis s. str.
