“…However, associations between this marker and heading and flowering date can be explained by the proximity of the Ppd-D1 gene on the genetic map. The significance of SSR locus gwm261 on the 2DS chromosome for improving the bread wheat yield potential was confirmed by its association with heading and flowering time in a specially designed double haploid population (Trkulja et al 2011). Confirmation of marker trait associations in our elite diverse material increases the possibility of using this candidate marker for MAS.…”

Brbaklic L., Trkulja D., Kondic-Spika A., Treskic S., Kobiljski B. (2013): Detection of QTLs for important agronomical traits in hexaploid wheat using association analysis. Czech J. Genet. Plant Breed., 49: 1-8.One of the main wheat breeder's goals is determining specific genomic regions which control important agronomical traits. Association analysis is a new strategy with high resolution in plant molecular breeding that could be used to improve the efficiency of marker assisted selection (MAS) for finding important QTLs (quantitative trait loci) or genes. A set of 96 diverse wheat genotypes was phenotypically measured during three growing seasons (2006/07, 2007/08, 2008/09). Microsatellite markers located near important QTLs were carefully chosen in accordance with existing literature data to validate marker trait associations (MTA). Genomic DNA was extracted using the CTAB method and PCR products were separated by capillary electrophoresis. The population structure was assigned based on molecular data in Structure v. 2.0 software, while association analysis was done by the Tassel program using the Q matrix. Nine significant associations were stable in all years investigated and eight MTA were detected to be significant in two growing seasons. Microsatellite markers which showed significant associations and stability in different seasons can be useful and suitable for marker assisted selection (MAS) in Serbian wheat breeding programs.

“…Heading and flowering phases represent a very important determinant of seasonal and regional adaptation of cereal cultivars (Trkulja et al, 2011). The adaptations are reflected in avoiding low air temperatures in flowering time (which can cause male sterility), as well as avoiding high temperatures and droughts during the grain filling phase.…”

The aim of the study was to examine the impact of microbiological and organic fertilizers on morphological and productive characteristics of triticale during a three-year period (2009/10-2011/12). A two-factorial field experiment was arranged using a randomized block design with four replications. The object of the study was the triticale winter cultivar Odisej, and the following treatments were applied: a control variant without fertilization, microbiological fertilizer ?Slavol? (Agrounik Serbia) 5.0 l ha-1, organic fertilizer ?Biohumus Royal offert? (Altamed RS) 3.0 t ha-1 + microbiological fertilizer ?Slavol? (Agrounik Serbia) 5.0 l ha-1. The results showed that the expression of the characteristics was significantly affected by the environment. The lowest values were obtained in the first year when the most unfavourable meteorological conditions were observed. The application of microbiological fertilizer had no impact on the stem length and grain weight per spike, but it significantly increased the number of fertile spikelets (3.7%), spike length (7.7%) and grain yield (18.6%). The combined application of fertilizers provided better results for all the examined characteristics, while in comparison with the control, the differences ranged from 4.3% for the number of fertile spikelets to 46.5% for grain yield. The strongest correlation was determined between the spike length and the number of fertile spikelets (r = 0.939**). The obtained results lead to the conclusion that under variable environmental conditions, the application of fertilizers has a significant impact on morphological and productive characteristics of triticale, and consequently on the stability of this crop production in the organic farming system.

“…Simple sequence repeats (SSRs), also known as microsatellites, have very important role in molecular research having high reproducibility, multi-allelic nature, co-dominant inheritance, high abundance and wide genome coverage (El-Awady et al 2012). Microsatellites are widely used in studies in different plant species (Stich et al 2006, Cadalen et al 2010, Brbaklić et al 2010, Trkulja et al 2011, Shah et al 2013. Numerous studies have pointed to the efficacy of SSR markers for determination of genetic diversity in the genus Solanum (Alvarez et al 2001, He, Poysa, & Yu 2003, Frary et al 2005, Garcia-Martinez et al 2006, Hu et al 2012.…”

Summary:The objective of this research was to assess genetic diversity using eight microsatellite markers in 30 tomato genotypes from the collection of the Institute of Field and Vegetable Crops in Novi Sad. The SSR markers were selected from publicly available data and Solanaceae Genome Network database. Genotypes were grouped into three clusters, using Ward`s hierarchical clustering method and Euclidean distance measure. Markers SSR248, TMS9, TMS42 and SSR111 had very high PIC (Polymorphism information content) values and can be recommended for the future studies.
