ABSTRACT

Trifolium repens is an important fodder crop in subtropical and temperate pastures of Nepal where it plays an important role in pasture management.  It was introduced in 1860 in Nepal from England and has since establishment in and o  utside of such pastures. The species has been known for exhibiting phenotypical differences but no attempt has so far been made for identification of its different variations. This is the first attempt where identification of varieties of Trifolium repens collected from different parts of Nepal was carried out.  “Flower color and leaf markings” singly or in combination was found to be the chief indicators for varietal differentiation. Morphological study of each variety of Trifolium repens, collected from Kirtipur, Dhunche and Chandanbari was carried out. Highest and lowest number value and average highest total value of different morphological parameters, were measured. SPSS/PC+, one way analysis of variance at 0.05 levels showed significant variations in nodule size, stipule length, petiole length, petiolule length, leaflet size, head length, floret number, peduncle length, floret length, calyx length, anther size and ovule number among eight varieties growing at Kirtipur, six at Dhunche and six at Chandanbari. The morphological evidence on the basis of above identifying phenotypic characters of Trifolium repens, growing at Krtipur, Dhunche and Chandanbari helps to conclude that eight varieties of Trifolium repens were identified using these criteria (i.e. Intra-specific diversity) in Nepal.
