Identification of salt tolerant barley (Hordeum vulgare L.) genotypes and effects of different levels of salinity on their growth, grain development and yield were studied. One hundred and eighty nine barley germplasms were subjected in five levels of NaCl concentration which were equivalent to Electrical Conductivity (EC) of 0, 10, 15, 20 and 25 ds/m. Among the genotypes 39 proved to be saline tolerant at 15 ds/m of salinity. Out of 39 genotypes, 33 were evaluated at Sonagazi and Patuakhali salt area of Bangladesh. All the genotypes were evaluated in the non-saline area at BARI, Gazipur to observe their performance in normal soil. Highest grain yield was recorded from the genotypes BSH-32 and BSH-142 over the three locations. Significantly higher yield was recorded from the experimental site of Gazipur followed by Patuakhali and Sonagazi. Tiller per plant had positive correlation with grain per spike, maturity and grain yield. Grain per spike and maturity was positively correlated with grain yield. From the multivariate analysis it appears that 1st, 2nd and 3rd principal components together account for 79 per cent of the total experimental variation. The two selected genotypes are expected to be released for commercial cultivation in the saline area of Bangladesh.       Key words: Barley, Genotypes, Selection, Salt tolerant, Bangladesh DOI = 10.3329/bjb.v36i2.1504 Bangladesh J.

Abstract. The objectives of this study were to estimate the heritability of yield and yield-related traits and to compute the correlation of grain yield with yield-related traits among the spring barley genotypes. The experiment was laid out in a complete block design with three replications in the Institute of Agriculture – Karnobat, Bulgaria during two consecutive years 2017 and 2018. Genotypes differed significantly for all the traits studied. Genotypic coefficients of variation were lower than the corresponding phenotypic coefficients in all the traits studied, indicating a considerable influence of the environment on the expression of the traits. Estimates for broad-sense heritability ranged from 0.65% for grain number per spike to 44.20% for 1000-grain weight. Moderate heritability coupled with relatively high genetic advance as a percent of the mean was found for 1000-grain weight suggesting a reliable possibility for improvement through selection. A significant and positive correlation between grain yield and number of spikes per m2 and grain weight per spike was found. Results of path analysis showed that grain weight per spike and number of spikes per m2 exhibited the highest direct effects on grain yield. The number of spikes per m2 was highly associated with grain yield but mostly influenced by environmental effects. The grain weight per spike should be prioritized for selection of superior spring barley genotypes under conditions of Southeast Bulgaria due to its highest direct effect on grain yield combined with higher heritability than that of grain yield. Moreover, it must be considered that the grain weight per spike had relatively low heritability in a broad-sense so the selection should be practised in later generations in replicated trials.

Barley Genotypes

In 2008-2011, grain yield and chemical composition were assessed in a set of spring barley genotypes with standard and changed amylose/amylopectin ratio (non-waxy and waxy, respectively) at two locations (Kroměříž, Žabčice). Genotypic as well as environmental effects were important for the variations in contents of chemical compounds. The waxy genotypes had statistically significantly higher levels of β-glucans and protein (6.9% d.m., 12.1% d.m., respectively) than genotypes with the standard starch character (5.4% d.m., 11.5% d.m., respectively). The hull-less waxy genotype KM2619.413.4 was statistically significantly different from all other genotypes in the set due to its highest content of β-glucans (10.80% d.m.). We found statistically significant differences between genotypes divided by the type of grain (hulled vs. hull-less) and also by the starch character (standard vs. waxy) in average starch contents as follows: hull-less genotypes with the standard starch composition (64.8% d.m.) > hull-less waxy genotypes (63.7% d.m.) > hulled genotypes with standard starch composition (61.4% d.m.) > hulled waxy genotypes (60.0% d.m.). Genotypes with elevated grain constituents (higher starch and BG contents) could be important from the point of a prospective use of barley for food production as was already found for example in the hulless waxy genotypes KM2645.412.3.4.6 (63.7% and 8.0%, respectively) and KM2551.469.1-2 (64.1% and 7.0%, respectively).

Lack of suitable barley varieties that exhibit high yielding is the major factor among several production constraints contributing to low productivity of barley in Nepal. The present study was done to evaluate and recommend the best performing barley genotypes. This study was conducted at research field of Hill Crops Research Program (HCRP), Dolakha, Nepal under National observation nursery (NON), initial evaluation trial (IET), coordinated varietal trials (CVT) and farmer's field trials (FFT) during winter seasons from 2017 to 2018. The results of these trials showed that in NON, genotypes namely B86023-1K2-OK3 (6.16 t/ha), Xveola-28/MATICO"S"10 (4.41 t/ha) and ACC#2079 (4.41 t/ha) produced higher grain yield over Farmer’s variety (3.57 t/ha). The pooled analysis over years of IET revealed that genotypes namely LG-51/Xveola-2-77-0-3-1-1-OK (2.12 t/ha) and B86099-2-1-OK (2.06t/ha) produced higher grain yield over standard check variety (Solu Uwa) (1.85 t/ha) and Farmer’s variety (1.95 t/ha). Similarly results of combined analysis over years of CVT showed that the genotypes namely B90K-007-0-2-2-0-OK (2.14 t/ha) and ICB90-0196-OAP-2K-OK (1.97 t/ha) produced higher grain yield over standard check variety (Solu Uwa) (1.12 t/ha) and Farmer’s variety (1.66 t/ha). In farmer's field trials (FFTs) the genotypes namely Muktinath ( Coll#112-14 (2.64 t/ha)), NB-1003-37/903 (2.23 t/ha) and Xveola-45 (2.04 t/ha) produced higher grain yield which was at par to standard check variety (Soluuwa) (1.58 t/ha) and Farmer’s variety (1.85 kg/ha). It is suggested that the superior genotypes derived from CFFT could be released and then recommended to farmers for general cultivation in Dolakha and similar other environments of Nepal.

Soil salinity is one of the main factors limiting cereal productivity in worldwide agriculture. Exploitation of natural variation in local barley germplasm is an effective approach to overcome yield losses. Three gene pools of North African Hordeum vulgare L. grown in Tunisia, Algeria and Egypt were evaluated at the reproductive stage under control and saline conditions. Assessment of stress tolerance was monitored using morphological, yield-related traits and phenological parameters of reproductive organs showing significant genetic variation. High heritability and positive relationships were found suggesting that some traits associated with salt tolerance could be used as selection criteria. The phenotypic correlations revealed that vegetative traits including shoot biomass, tiller number and leaf number along with yield-related traits such as spike number, one spike dry weight, grain number/plant and grain number/spike were highly positively correlated with grain yield under saline conditions. Hence, these traits can be used as reliable selection criteria to improve barley grain yield. Keeping a higher shoot biomass and longer heading and maturity periods as well as privileged filling ability might contribute to higher grain production in barley and thus could be potential target traits in barley crop breeding toward improvement of salinity tolerance. Multiple selection indices revealed that salt tolerance trait index provided a better discrimination of barley landraces allowing selection of highly salt-tolerant and highly productive genotypes under severe salinity level. Effective evaluation of salt tolerance requires an integration of selection indices to successfully identify and characterize salt tolerant lines required for valuable exploitation in the management of salt-affected areas.

Abstract A field experiment was carried out for over two seasons (autumn and spring) as a split–split plot scheme based on a randomized complete block design with three replications. The main plots included two irrigation levels of the maximum available water depletion (maximum allowable depletion (MAD)) of 55 and 85% as non-stress and drought-stress environments, respectively, and the subplot accommodated two levels of nitrogen (0 and 62.5 kg N/ha, urea fertilizer); also, 20 barley genotypes were assigned to the sub-subplots. The biplot analysis of both sowing seasons showed that grain yield (GY) had a high positive correlation with total biomass (TB), whereas it had a high negative correlation with proline and total soluble carbohydrate as drought-tolerance-determinant characteristics. The genotypes which had the lowest and highest GY ranked significantly (P ≤ 0.01) different with changing the sowing season under each irrigation level, indicating a larger plant interaction and non-stability in response to the season change (about two-fold), as compared to the change in the irrigation conditions. It could also be concluded that barley genotypes might experience a higher decrease in GY and sensitivity to water deficit in the autumn sowing season, as compared to the spring planting season, which was also intensified by nitrogen application. However, the response to nitrogen application depends on the plant genotype.

The objective of this experiment was to estimate the magnitude of genotype X environment interaction on grain yield and yield related traits. Twelve varieties of food barley were included in the study planted in randomized complete block design with three replications. The ANOVA of combined and individual location revealed significant differences among the food barley genotypes for grain yield and other traits. The results of ANOVA for grain yield showed highly significant (p≤0.01) differences among genotypes evaluated for grain yield at Maychew and significant (p≤0.05) differences in Korem, Alage and Mugulat. The ANOVA over locations showed a highly significant (p≤0.01) variation for the genotype effect, environment effects, genotype X environment interaction (GEI) effect and significant (p≤0.05) variation for GEI effect of yield and for most of the yield related traits of food barley genotypes. Haftysene, Yidogit, Estayish and Basso were the genotypes with relatively high mean grain yield across all locations and they are highly performing genotypes to the area. Among locations, the highest mean grain yield was recorded at Korem and it was a suited environment to all the genotypes whereas Mugulat is unfavoured one.

Abstract AimsThe general aim of this meta-analysis is to synthesize and summarise the mean response of barley yield variables to elevated CO2 (eCO2) and its interaction with temperature and N fertilization. Methods The present study quantitatively synthesized the response of barley to eCO2 and its interaction with temperature, and Nitrogen (N). A meta-analysis procedure was used to analyse five yield variables of barley extracted from 76 articles to determine the effect size and the magnitude in relation to eCO2 and its interaction with temperature and N. Results CO2 enrichment increased biomass (23.8%), grain number (24.8%), grain yield (27.4%), and thousand-grain weight (5.6%). However, responses to eCO2 were affected by genotype, additional stress, and experimental conditions. In comparison, genotype “Anakin” shows the highest response of biomass (47.1%), while “Genebank accessions” had a higher grain number (46.1%) and grain yield (57.1%) under eCO2. The maximal enhancement of barley yield was observed when plants grow under a combination of eCO2 and higher nitrogen fertilizer (>100 kg ha-1). Nevertheless, biomass (-12%), and grain yield (-17%) responses were lower when eCO2 is combined with high temperature (>25 °C). It was further noted the response of barley yield to eCO2 was higher in the growth chamber than in other CO2 exposure methods. Moreover, comparing pot-rooted versus field-rooted barley plants, a higher response of biomass and grain yield was observed for pot-rooted plants. ConclusionsOverall, results suggest that the maximal barley production under eCO2 will be obtained in combination with high nitrogen fertilizer and optimal temperature (21-25 °C).
