“…Understanding agronomical, phenological, and physiological traits associated with grain yield can help wheat breeders to accelerate genetic improvement in grain yield potential. Grain yield in wheat has been divided into its components, namely, grain number and grain weight (JOUDI, 2017;RUKAVINA et al, 2017). Breeding effort on increasing grain yield of wheat will incessantly continue because it is an indispensable product (KUTLU et al, 2017).…”

The objective of this study was to examine the effect of the variety, locality and year on the morphological and productive parameters of the spelt wheat obtained in the organic production system. Four spelt varieties were grown at three agroecological environment (Pančevo, Bogdanica and Zlatar), in southeast Europe, Serbia. They are used in order to determine general adaptability in different environment in three years trial (2014-2016). Analysis of the selected production parameters of spelt wheat, according to variety, locality and year, were conducted by the Principal Component Analysis (PCA). The PCA of the presented data explained that the first two components accounted 86.02% of the total multivariance in the eleven variable factor space. The results showed that the highest values of a number of plants, number of stems, number of spikes, plant height,the number of grains in the spikes, weight of grains per spike, yield of above ground biomass, harvest index and yield of hulled grain were observed for the crops grown in Pančevo, regardless of the spelt wheat variety and year. The samples grown in Bogdanica showed to be very sensitive to the spelt wheat variety, in terms of hull index value. The highest value of mortality stems has been found in Zlatar, regardless of the spelt wheat variety, or the year.

“…A comprehensive morphological characterisation methodology for each cultivated plant or crop group, as defined by the guidelines of the International Union for Protection of New Varieties of Plants (UPOV) and based on distinctness, uniformity and stability (DUS) criteria, is routinely carried out during the official process of variety registration to correctly identify plant varieties and to protect plant breeders' intellectual property rights. These characteristics also proved suitable for investigating genetic variability of bread wheat germplasm (Donini et al, 2000;Rukavina et al, 2017;Petrović et al, 2018), while little has been done to evaluate the genetic diversity of durum wheat cultivars developed in Serbia.…”

Estimation of the level of durum wheat germplasm genetic diversity is important for its classification and efficient use in breeding programmes. The aim of this study was to assess genetic diversity of durum wheat genotypes developed at the Institute of Field and Vegetable Crops in Novi Sad, Serbia, with 26 morphological characteristics based on the International Union for Protection of New Varieties of Plants guidelines. The Shannon diversity index was used as an indicator of morphological diversity and it ranged from 0.283 for glaucosity of lower side of the flag leaf blade and density of hairiness of uppermost node of the culm, to 0.950 for the ear colour, with the mean value of 0.616, indicating a medium to high level of morphological diversity. On average, the diversity was higher for traits relating to generative organs than for those associated with vegetative plant organs. The 21 morphological characteristics were sufficient to distinguish unique profiles of all durum wheat genotypes. The estimation of varietal diversity and identification of morphological characteristics with the highest discriminative power were done by multiple correspondence analysis. The traits that contributed the most to the distinction of genotypes were the ear colouration, length of beak of the lower glume, lower glume shape, ear length of awns at tip relative to ear length and colour of awns. Morphological characterization using the traits with the highest discriminative power could be a useful complementary method for durum wheat germplasm classification and diversity analysis.
