“…Of the 113 accessions evaluated, 14 did not lodge at the CPAC site and 8 did not lodge at the SPM site. Still, at the SPM site, 87 The values for lodging obtained in the present study were higher than the averages of 28% reported by Mirosavljević et al (2015), in trials performed with winter barley during three years, and of 25%, by Smith et al (2013), for seven cultivars released in the United States. The Colombian genotypes MCU 3592 PI 402070, MCU 3576 PI 402054, and MCU 3452 PI 401930, as well as the control cultivar BRS 180, stood out positively and did not present lodging at both environments.…”

-The objective of this work was to estimate the genetic, phenotypic, and environmental parameters of 113 barley accessions (Hordeum vulgare), previously selected based on high yield, in an irrigated production system in the Cerrado (Brazilian savanna), for use in breeding programs in Brazil. The experiment was conducted in 2013 at two sites in the Federal District, using a randomized complete block design with three replicates. The evaluated traits were: grain yield, kernel plumpness, thousand grain weight, plant height, lodging, and days to heading. Significant differences were observed between environment and accessions for all studied traits, as well as genotype x environment interaction. The MCU 3832 PI 402310, MCU 3484 PI 401962, CI 08053 Custer, MCU 3634 PI 402112, and MCU 3816 PI 402294 accessions stood out regarding grain yield and kernel plumpness. It is possible to obtain high selection gains with high heritability values. However, indirect selection is not recommended in the experimental conditions due to the low genotypic and phenotypic correlations obtained. It is also possible to select barley accessions with high yield and early heading date simultaneously, an important factor in the genotype selection process for future experiments. The accessions from Colombia are the most adapted to the Cerrado conditions.

“…The presence of high genotypic variation in grain yield and grain yield components (Tables 1 and 2) indicated that the genetic diversity within advanced breeding lines could provide useful source of variation for further yield improvements, as previously reported by Gonzalez-Navarro et al (2016) in wheat and Mirosavljević et al (2015b) in barley. Grain yield was mainly related to the high grain number per unit area, while relationship with grain weight was less pronounced (Figure 3).…”

The simple methods used for indirect biomass determination are recognized as potentially important tools for crop growth prediction. The normalized difference vegetation index (NDVI) is widely used for assessing crop biomass, yield, photosynthesis, and nitrogen management. Aims of this study were to determine the variation in NDVI values and relationship of the NDVI with the most significant agronomic properties in the elite genotypes of two-rowed winter barley. The experiment included elite two-rowed winter barley genotypes and was carried out in two growing seasons. NDVI were measured at mid-anthesis, while grain yield and grain yield components were determined from combine harvested samples at maturity. Results from this study showed that the influence of genotype was mainly responsible for variation in most studied traits. Grain yield of two-rowed barley cultivars was more related to high grain number per unit area than to grain weight. NDVI values at anthesis in both growing seasons were positively associated with grain yield (R 2 = 0.444 and R 2 = 0.386), grain number (R 2 = 0.387 and R 2 = 0.507) and plant height (R 2 = 0.352 and R 2 = 0.364), while relationship with grain weight was not significant. Significant genotypic variation for NDVI values and the presence of significant positive relationship with grain yield and grain number indicated that NDVI measurement at anthesis could be efficiently used for indirect identification of productive two-rowed winter barley genotypes.

“…Posmatrano za sve ispitivane osobine faktor sredina se pokazao kao najznačajniji upravo kod mase 1000 zrna. Mirosavljević et al (2015) su dobili drugačije rezultate, pa se u radu navodi da je faktor genotip bio dominantan (45%) po pitanju variranja, dok je faktor sredina imao najmanje uticaja na variranje (19%). Pržulj i Momčilović (2010) navode da je interakcija genotip x sredina najviše uticaja imala na variranje mase 1000 zrna kod sorti ozimog ječma.…”

Domestikacija, selekcija i moderno oplemenjivanje suzili su genetičku varijabilnost ječma, a time stvorili potrebu za ponovnim stvaranjem varijabilnosti kao baze za oplemenjivanje ove biljne vrste. U radu je tokom dve godine ispitivano 4 sorte ječma i 48 lokalnih populacija iz Banke biljnih gena Srbije. Analizirana je fenotipska varijabilnost i genetička struktura dve kvantitativne osobine klasa: dužina i širina klasa, i jedna osobina zrna: masa 1000 zrna, u populaciji sa genotipovima poznatog tipa vegetacije i oblika klasa. Prosečna dužina klasa iznosila je 4,2-10,2 cm, širina 0,65-1,27 cm, a masa 1000 zrna 27,58-51,35 g. Analiza varijanse imala je značajnu F vrednost za sve izvore variranja kod svih osobina. Analizom šesnaest SSR markera detektovano je ukupno 105 alelnih formi. Posmatrajući grupe, tip vegetacije i oblik klasa, diverzitet gena je bio najveći kod jarog (dvoredog i šestoredog) i šestoredog (jarog i ozimog) ječma. Rezultati AMOVA testa za oblik klasa su pokazali visoko značajne vrednosti za oba izvora varijacije, dok je međugrupna komponenta bila dominantna i za tip vegetacije (91,26%) i za oblik klasa (90,83%). UPGMA klaster analizom konstruisan je dendogram kojim su 52 genotipa svrstana u tri glavne grupe i 11 podgrupa. Dobijeni rezultati su pokazali da u proučavanoj kolekciji postoji značajna varijabilnost ispitivanih osobina, koja se može koristiti u oplemenjivačkim programima ječma.
