THE AMELIORATION OF THE MUSCAT D´ADDA VARIETY THROUGH CLONE SELECTION

Abstract

During the period 1983 – 1999, at INCDBH Stefanesti, the elite Mt. d´Adda 22 St. was selected and grown in contestplantations in order to be destined to the fresh grapevine consumption The identification of the biotypes(clones)having superior quality and production characteristics which manifest constantly, has been achieved through the studyof the elites chosen in comparative fields, using the method of repeated determinations in groups of years, underspecific vineyard conditions. Through repeated verification of the elites in the contest plots the elite Mt. d´Adda 22 St.stood out by superior quality, constant and sustained production of grapevines and the maintenance of the qualitycharacters. The elite was omologated in 2009. There had been identified and studied the clone elites which maintainedtheir productivity and quality characteristics during 2-3 years, which subsequently had been put to vegetativepropagation with a view to obtain the initial grafting material according to the intensive amelioration schemes.
