| dc.description.abstract | Barley (Hordeum vulgare L.)is one of the most important field crops in Palestine. The area Planted with barley exceeds 9270 ha. The average productivity in Palestine is about 1.7 ton/ha, which is less than 56% of average world productivity. This shortage is due to the effect of unfavourable local environmental conditions for used cultivars. Introducing high yielding and well-adapted cultivars could be one of the best solutions to overcome the low productivity of barley in palestine. Eighty-four accessions of landraces and cultivated varieties of barley were collected from different countries, mainly from the Fertile Crescent. A field experiment was conducted at the Faculty of Agriculture – An-Najah National University during two growing seasons 2015-2016 and 2016-2017 to evaluate several agronomical traits and to test the agronomic performance of the barley varieties under rain-fed conditions. The traits that were analysed are days to stem elongation, days to heading, days to maturity, tiller number, spike number, plant height, total grain yield, thousand kernel weight and vegetative biomass. The results obtained from this study led to a clear morphological identification of studied varieties. Also the results indicated high genetic diversity among barley varieties, which make them potential sources for selection and hybridization programmes. The results also show that there are clear differences in most of the varieties between season 2015-2016 and season 2016-2017. These differences are due to the different climatic conditions between the two seasons in addition to the biotic and abiotic factors. The results also indicated that many of these genotypes are promising for grain yield as MK_RB_269 (409 g/m2) variety, and others for vegetative biomass yield as MK_RB_113 (2062g/m2) variety. Further studies are needed to compare the productivity of these genotypes with international varieties and identify QTL controlling the productivity of these genotypes and to study the variation between and within these genotypes at the molecular level. | en_US |
