Morphological and cytological variability in interspecific hybrids Trifolium pratense x T. medium

Original language description

Trifolium pratense is a high yielding, high quality fodder crop. However, it shows rather low persistency, which could be overcome by hybridisation with a species creating rhizomes. Hybrids between T. pratense and T. medium have been previously obtainedby embryo rescue and the number of chromosomes was evaluated by flow cytometry. The DNA content converted into number of chromosomes ranges from 27 to 57 in individual plants. This work aimed at the evaluation of twelve morphological traits (stem weight/length, internode number, length/width of the central leaflet of the uppermost triple leaf below the top head, length/ width of the central leaflet of the triple leaf on the 4th internode, stem thickness on the 4th internode, stem and head number per plants, intensity of white marks and average leaf area) in ten populations (550 plants) derived from F1 hybrids and in the parental species. The significance of morphological differences was determined by ANOVA test. Nearly all examined trai
