CORRELATIONS BETWEEN MORPHOLOGICAL, AGRONOMIC AND CHEMICAL CHARACTERISTICS OF F₁ FLUE-CURED TOBACCO HYBRIDS

Abstract

Istraživane su fenotipske koleracije morfoloških, gospodarskih i kemijskih svojstava F₁ hibridnih sorata duhana tipa „flue cured“. Za izračunavanje korelacije su korišteni dvogodišnji prosjek morfoloških, gospodarskih i kemijskih svojstava. Prinos je bio u najvisoj korelaciji sa duljinom srednjeg lista, duljinom vegetacije, zatim sa visinom biljke i brojem listova po biljci. Kvaliteta osušenog lista (indeks vrijednosti) nije bila u korelaciji s nijednim kemijskim ni morfološkim svojstvom. Isto tako, indeks vrijednosti nije bio koreliran s prinosom. Od kemijskih svojstava je sadržaj reducirajućih šećera bio u značajnoj pozitivnoj korelaciji s visinom biljke, duljinom srednjeg lista, duljinom vegetacije i prinosom.Phenotypic correlations between morphological, agronomic and chemical characteristics 12 F₁ flue-cured tobacco hybrids were calculated. The data of a two year variety test, conducted as a three replication rendomized complete block design Jezero near Vrgorac, were used for for the calculations. Yield was in the highest correlation with the lenght of the middle leaf, leniht of the vegetation period, plant hight and number of leaves per plant. Ouality of the cured leaves was very little in correlation with the morphological and chemical characteristic studied. Also, the cured leaf quality was very little in correlation with yield. Among chemical characteristics only content of reducing sugars was in a significant correlation with height of plant, lenght of middle leal, lenght ,of vegetation period and yield
