The cropping and productivity potencial of peach cultivars introduced early epoch maturation

Abstract

Assortment of peach is very dynamic. Many new varieties registered each year in Italy, France, USA and other countries. Introduction of a permanent process imposes the need to study newly varieties in certain environmental conditions to determine their economic and biological characteristics, to recommend the best production practices for intensive cultivation. Investigations were carried out in production-test plantation AD "Plantations" - Agrokombinat "13 July" in Podgorica in the period 2005-2009. year. Tests included seven newly introduced varieties of peaches and nectarines (Early Crest, Early May Crest, May Crest, Qwin Cest, White Crest, Rita Star and Andrew) and two standard varieties (Spingbelle and Royal Glory). In these cultivars to investigate major biological properties: blossom, pollen, fruit, ripening time and yield. Investigated peaches on average flourished in the range of 3.11 (Rita Star) to 19.03. (Qwin Crest and White Crest). The best germination of pollen had a variety Early May Crest (85.66%), and the smallest variety Crest White(74.00%). Fruit set on average in all the varieties was (87.00%), the largest recorded in the variety May Crest (95.30%) and lowest (79.33%) had a variety of White Crest. Yield of most varieties of peaches is balanced by age, and volume are in the group of low to high productivity
