“…Protein content is a primary quality indicator for corn grains. Mut et al [33] and Peterson et al [34] reported that the grain protein content changed from 3 to 4% and 10.0 to 18.0%, respectively within different oat genotypes cultivated in different environments. The protein content was mainly affected by the environment rather than the genotype.…”

The interaction of genotype by the environment is very common in multi-environment trials of maize hybrids. This study evaluates the quantity and the quality of grain production and the stability of four maize genotypes in a field experiment that was conducted in five different locations for two years. In order to make a reliable evaluation of the performance of genotypes in the environments, principal components analysis (PCA) was used to investigate the correlation of the yield, soil properties and quality characteristics, while the additive main effects and multiplicative interaction (AMMI) analysis detected the narrow adaptations of genotypes at specific mega-environments. For the yield, AMMI analysis indicated that a group of five environments (ENV1, ENV8, ENV6 ENV10 and ENV9) gave higher yields than the mean value and at the same time had low first interaction principal components axis (IPC1) scores, indicating small interactions. Regarding protein and fiber contents, ENV1 and ENV2, gave the highest values and this could be attributed to the high concentration rates of nutrients like Mg, Ca and the soil texture (C). Specifically for the protein, the results of the analysis indicated that certain environment would provide more protein content, so in order to obtain higher grain protein, growers should grow in certain locations in order to improve the content of this quality characteristic, certain genotypes should be used in certain environments.

“…Dužina trajanja perioda nalivanja zrna nalazi se pod značajnim uticajem ekoloških faktora, pre svega visokih temperatura koje skraćuju ovaj period (Hurkman and Wood, 2011). Selekcijom genotipova koji ranije cvetaju može se uticati na formiranje većeg broja cvetova -potencijalnog akceptora asimilata i duži period nalivanja zrna, odnosno izbor prinosnijih genotipova (Mut et al, 2018).…”

IzvodKlimatske promene i povremeni deficit semena jarog ovsa ukazuje na potrebu raspolaganja fakultativnim sortama koje se mogu sejati tokom jeseni i ranog proleća. U cilju utvrđivanja uticaja vremena setve u jesen i proleće na prinos i komponente prinosa tokom 2015/16. i 2016/17. sezone, ispitivane su četiri fakultativne linije i fakultativna sorta ovsa Sana u agroekološkim uslovima Banjalučkog regiona. Ove linije i sorta Sana selekcionisane su u JU Poljoprivredni institut Republike Srpske, Banja Luka. Setva je obavljena u jesen i u proleće, a primenjena je tehnologija uobičajena za gajenje ozimog i jarog ovsa. Prinos po jedinici površine, dužina metlice, masa metlice, broj zrna po metlici i masa zrna po metlici imali su veće vrednosti kod svih linija i sorte Sana u jesenjoj nego prolećnoj setvi. U jesenjoj setvi prinos je iznosio 7,00-8,20 t ha -1 , a u prolećnoj setvi 6,04-6,88 t ha -1 . Maksimalni prinosi ostvaruju se setvom 500 klijavih zrna m -2 . Linija fakultativnog ovsa BL-2 ostvarila je najveći prosečni dvogodišnji prinos i u jesenjoj (8,20 t ha -1 ) i u jaroj (6,88 t ha -1 ) setvi. Sorta Sana u jesenjoj setvi ostvarila je prosečan prinos od 8,10 t ha -1 . Rezultati ovoga testiranja ukazuju na značaj stvaranja fakultativnih sorti strnih žita, čime će se rešiti povremeni deficit semena jarih sorti, koje se inače manje semenare. AbstractClimate change and occasional seed deficit of the spring oats indicates the need to dispose of with facultative varieties, which can be sowed during autumn and early spring. In order to determine the impact of sowing time in autumn and spring on yield and yield components during 2015/16 and 2016/17, four facultative lines and the facultative variety oats Sana in the agro-ecological conditions of the Banja Luka region were tested. These lines and variety Sana have been selected by the PI Agriculture Institute of the Republic of Srpska, Banja Luka. The sowing was carried out in autumn and in the spring, with commonly applied technology for cultivation of spring oats. The yield per unit area, the length of the tassel, the mass of the tassel, the number of grain and the weight of the grain per tassel had higher values in all lines and varieties of Sana in autumn than in the spring sowing. In autumn, the yield was 7.00-8.20 t ha-1, and in the spring sowing 6.04-6.88 t ha-1. The maximum yield is achieved in the rate of the 500 emergence grains m-2. The line of facultative oats BL-2 has achieved the highest average two-year yield in autumn (8.20 t ha-1) and in the spring (6.88 t ha-1) sowing. Variety Sana in autumn sowing achieved the average yield of 8.10 t ha-1. The results of this research indicate the importance of creating facultative varieties of the spring grain, which will solve the occasional seed deficit of spring varieties, which are otherwise less grown.

“…Ключевым вопросом адаптивной селекции является проблема учета взаимодействия генотипа и среды. Отбор в одних условиях может не обеспечивать преимущества генотипов в других, что делает актуальным получение информации о генотипах и средах на ранних этапах селекции [7][8][9].…”

Under conditions of climate change, the assessment of the stability of genotypes is of particular importance. To conduct directed selection of genotypes with a narrow or broad reaction rate, it is necessary to assess their stability already in the early stages of breeding. The aim of the study was to study the stability of breeding significant traits of oat and barley samples in contrasting ecological and geographical conditions. 25 oat samples and 25 barley samples were studied over 3 years under contrasting conditions in St. Petersburg and the Tambov region. Varieties are characterized by average values of economically valuable traits and genotype regression coefficients on the influence of the bi environment according to Eberhart and Russell. The most sensitive to a change in the ecological and geographical situation were the durations of the germination-heading, germination-harvest periods and grain yield. These characters varied to a greater extent depending on the cultivation conditions than on the genotype. According to regression coefficients for environmental conditions, significant differences in genotypes were only in yield. Contrasting groups of varieties were distinguished by regression coefficients on environmental conditions, genotypes with high productivity. The durations of germination-heading, germination-harvest, the plant height reacted to the change in the environment the same in different varieties. The duration of the growing season was determined by the sum of effective temperatures above 15C. The reduction of the growing season in both crops was 3 days with an increase in the sum of effective temperatures above 15C by 100C.
