Interspecific hybrids Trifolium pratense x Trifolium medium as the source of new diverzity
Original language description
Red clover (Trifolium pratense) is very important forage crop from the leguminous family. It is an allogamous diploid with a 418 Mb genome. T. pratense is a high-quality fodder crop but shows a low persistency, which may be overcome by hybridisation withspecies that produce rhizomes. Hybrids between T. pratense (2n = 4x = 28) and T. medium (2n = 8x = 64) have been previously obtained by embryo rescue. The aim of this study was to evaluate interspecific variability of hybrids on the cytological level and on the phenotypic level via 16 characteristics. Plants of 99 families in two breeding nurseries had comparable chromosome numbers in five groups: 2n = 28 (76 and 66% of plants), bellow of 28 chromosomes (8.5 and 6.4% of plants), 2n = 29, 30 (15 and 26%of plants), 2n = 31, 40 (0.4 and 1.2% of plants) and 2n = 41 to 46 (0.1 and 0.3% of plants). The phenotypic characteristics were evaluated in three years. There were significant differences between the hybrids and T.
