Variation of Morphological and Agronomic Traits in Hybrids of Trifolium pratense x T. medium and a Comparison with the Parental Species

Popis výsledku v původním jazyce

Trifolium pratense L. is a high-yielding and high-quality fodder crop. However, it shows low persistence, which may be overcome by hybridisation with species that produce rhizomes. Hybrids between T. pratense L. and T. medium L. were previously obtainedby embryo rescue. The aim of this study was to evaluate 16 characteristics (stem weight, stem length, internode number, length/width ratio of a central leaflet of the trifoliate leaf on the 4 th internode, stem thickness on the 4 th internode, average leaf area of the trifoliate leaf, weight of dry plant, plant length, stem and head number per plant, head number per stem, seed weight per plant, seed weight per head and dry matter per stem) in the hybrid plants derived from F1 hybrids and in both parental genotypes. The characteristics were evaluated in 500, 745 and 112 hybrid plants in the years 2006, 2008 and 2009, respectively. The significance of the morphological differences was determined by the general linear model and generalised
