Comparative mathematical analysis of economically important ampelographic indicators in white wine vine varieties (<i>Vitis vinifera</i> L.)

A comparative mathematical analysis of economically important ampelographic indicators was performed in 32 local, introduced and newly bred white wine vine varieties. It found that depending on the similarity remoteness values studied indicators, varieties are grouped into three generalized clusters. In first, characterized by a longer budding period relatively lower productivity. second, they have similarities length period, long - technological maturity, moderate productivity, close content volatile acids wine. third, two Gergana Misket Markovski, which most fertile productive with smallest number seeds berries. There is high variability individual according to valuable indicators. The bunch average weight per 100 berries stronger direct effect formation yield varieties, weight, width, percentage mesocarp berries, berry as well theoretical significantly affect indirectly productivity vines.
