Analysis of fertility on the Merlot clones (Vitis vinifera L.), by applying the method of correlation.

In this research were included seven clones of the variety Merlot (R-12, R-18, R-3, 181, 184, 348, 346). Fertility of each clone is determined by elements: fertility shoots per vine (%),absolute coefficient (number of clusters per fertile shoot), mass of bunch, and the yield expressed of unit area or kg/m2.The obtained results from this work were statistically processed using the SPSS statistical software package 19, from where it can be measure the frequency, the percentage share of data, measures of central tendency (median, standard deviation, dispersion, arithmetic mean), such as graphic representation of data (a histogram).The analysis showed than all clones had larger correlation coefficient or there exists a greater dependence between the mass of the cluster and yields. From all clones, only two of them (R18, 346) proved more than greater dependence or greater correlation coefficient between absolute coefficientand the percentage of fertility shoot. The Merlot clone 348 proved the highest correlation between the mass of the cluster and yields where correlation coefficient is 0.983 which is approximately the value of 1, which indicates a very high connectivity.
