Sažetak
Winter wheat yield is a complex, quantitative trait directly or indirectly influenced by other plant traits. An understanding of the interrelationships between important agronomic traits and yield of winter wheat could help to improve breeding results. The objectives of this paper were to examine correlations between several winter wheat traits and their direct and indirect effects on kernel yield. Research work was conducted during two growing seasons in East Croatia (2005/ 06 and 2006/07) on 11 winter wheat genotypes. Nine genotypes were advanced breeding lines and two registrated Croatian cultivars Žitarka and Srpanjka. Six traits were included in investigation: ear number per m2, plant height, number of spikelets per ear, number of kernels per ear, 1000 kernel weight and kernel yield. Path- coefficient analysis was used to evaluate relations between examined traits. Positive and significant correlation was found between ear number per m2 and 1000 kernel weight, ear number per m2 and kernel yield, number of kernels per ear and kernel weight. Ear number per m2 was in significant negative correlation with plant height and spikelets number per ear. Number of kernels per ear and ear number per m2 had significant positive direct effects on 1000 kernel weight and kernel yield, while the spikelets number per ear had negative direct effect on kernel yield.
