The objectives of this study were to assess the genetic variability of yield, yield related traits and to estimate direct, indirect effects of trait associations. Seventeen varieties were evaluated and subjected to the analysis of variance using RCB design, in Eastern Amhara Ethiopia. The varieties differed significantly for most of the characters and had wide range of mean values, which indicated the existence of variations among the tested varieties. Estimates of phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) were generally low. The highest GCV and PCV values were recorded on grain yield (51) and plant height (60). The PCV values were slightly greater than the GCV values. Grain yield, plant height, protein content and grain size had relatively high heritability. Grain yield gives high heritability value accompanied by high genetic advance which is good indicator for selection. Grain yield had positively and significantly correlated with date of maturity. Grain yield negatively correlated with protein and positively associates with starch.

Malt barley (Hordeum vulgare L.) is one of the most important industrial crop and highly demanded due to the expansion of brewery factories in the country and the unique nature of the grain for malt. However, its production and productivity is very low compared to other countries due to limited numbers of high yielding malt barley varieties, partial use of agronomic and production and low genetic base due to these farmers were highly resistance to produce malt barley in north eastern Ethiopia. The objectives of this study were to identify malt barley varieties preferred by farmers. Seventeen varieties were evaluated in participatory variety selection (PVS) using RCB design, in Eastern Amhara. The varieties differed significantly for most of the characters and had wide range of mean values, which indicated the existence of variations among the tested varieties. Participatory variety selection was done using pair wise ranking and direct matrix ranking methods. It provides an opportunity to the farmers for variety selection and creates a chance to adopt the new selected varieties easily. Variety HB-1533, IBON174/03, EH-1847 and Friegbs scores the highest yield and highly preferred by farmers which perk up by the community. The above varieties were selected for further multiplication, seed dissemination.

Microbiome is a term that is used to comprise the entire microorganism’s genome that inhabitant symbiotically in the human gut, the microorganism inhabiting together are the bacteria, archea, viruses and fungi. it is the requirement of the time that we consider the review as well as the association of micro biome data for the inventory of the new therapeutic approaches which should be in the consideration of the traditional approaches in concept wise along with the methodologies.
