Jakešova,H,CechováL,Řepková,J.: The Evaluation of Morphological Variability in Interspecifíc Hybrids Trifolium pratense x T. medium and Comparison with The Parental Species.

Popis výsledku v původním jazyce

Trifolium pratense is high yielded as well as high quality fodder crop. However, it shows lower persistency, which could be overcome by hybridisation with a species creating rhizomes. Hybrids between T. pratense and T. medium háve been previously obtained by embryo rescue and the number of chromosomes was evaluated by flow cytometry. This work was aimed at the evaluation of twelve morphological traits (stem weight/length, internodes numbers, length/width of a centrál leaflet of the triple leaf under thetop head, length/ width of the centrál leaflet of the triple leaf on the 4th internodes, stem ťhickness on the 4th internodes, stem and head number per plants, intensity of white marks and average leaf area) in ten populations (550 plants) derived fromFI hybrids and in the parental species. The significance of morphological differences was determined by ANOVA test. Nearly all examined traits were intermediate in hybrids; they reached higher values than in T. medium and lower values tha
