Association studies in nectarine for various horticultural traits in north-western Himalayas

Abstract

Five nectarine cultivars were evaluated at the Model Farm, Directorate of Research, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2014-16 with the objective to study the association between yield and its dependent variables. Highly significant and positive phenotypic and genotypic correlations of yield were found with tree spread, tree volume, and fruit length and fruit weight. Maximum positive direct effect cited towards yield were contributed by fruit weight, tree spread, stone length, flower intensity, stone weight, total soluble solids, number of days from full bloom to maturity, pulp to stone ratio, tree height, duration of flowering, fruit set and trunk girth.
