Sažetak
Varijabilnost i korelacije morfoloških karakteristika osam sorti ukrasne bundeve ispitivane su u poljskim uslovima. Varijabilnost visine biljke, dužine ploda, širine ploda, težine ploda, debljine kore ploda, dužine drške, obima drške, dužine lista, širine lista, dužine semena, širine semena, debljine semena i broja plodova po biljci u ispitivanom materijalu je velika. Najveća varijabilnost se ispoljava u osobinama ploda i može poslužiti kao dobra osnova za budući oplemenjivački rad na dobijanju ukrasnih bundeva. Korelacije između ispitivanih osobina ukazuju na značajan uticaj osobina semena i lista na osobine ploda. Sorte su fenotipski razdvojene u dve slične grupe pomoću multivarijacione analize.
Abstract
Variability and correlations among morphological features of eight ornamental pumpkin varieties were studied under field conditions. The variability of plant height, fruit length, fruit width, fruith weight, fruit peel thickness, length and circumference of handle grip, leaf length, leaf width, seed length, seed width, seed thickness and number of fruits per plant in the examined material was high. The highest variability was related to the fruit properties. This variability represents a good source for future breeding programs. Correlations between the traits indicated a significant influence of leaf and seed characteristics on fruit properties. Multivariate statistical analysis provided differentiation of varieties on two phenotypically different groups.
