Abstract
SUMMARYThe object of the present study was to gain additional information about the genomic structure of F. pratensis, F. arundinacea var. glaucescens, F. arundinacea (2 n = 42), F. Mairei and to confirm through chromosome pairing in these species and their interspecific hybrids the homologies suggested on karyotypic basis between their chromosome complements. Based on two sources of evidence (karyotype and meiosis of F1 progeny) genomic formulae to different species are assigned. 1. In the triploid hybrids involving F. pratensis X F. arundinacea var. glaucescens, chromosome pairing at M-I could be represented by a mean of 7.48I, 5.48II, 85III. In some cells as many as 19 chromosomes were associated. (a) This pairing is regarded as allosyndetic though some amount of intergenomic pairing was also observed.(b) Considering the karyotypic similarities between the satellited chromosomes of F. pratensis and some of those of glaucescens, and also the meiosis of their F1 progeny, the genomic constitution of prate...
