“…Similarly [13] total of 22 barley landraces was collected from different farmers for agro morphological evaluation 3 parameter which show high variation in spike length, spike colour and spike type, but in case of spike length, it show high variability in spike length (70%) from 5 to 9 cm. [14] it was investigate the same result which was related to the present study because for morphological characterization it was take the same both qualitative and quantitative traits which show similarities and variation like present study, especially in kernel covering.…”

Integrated scoring of salinity stress on agro-morphometric and seed storage proteins of barley landraces. Pure and Applied Biology. Vol. 9, Issue 1, pp963-978. http://dx. AbstractAbiotic stress factors, especially high temperatures and salinity, represent the major constraints limiting agricultural production. In present investigation barley forty selected lines was treated in pods at three salt concentrations (25, 50 and 75 mM NaCl) and one control line. In present investigation the maximum salinity affect the yield, spike and total biomass of the plant. For the genetic diversity among barley lines two method were applied morphological evaluation under IPGRI 1994 descriptor and protein profiling, a significant genetic variation index were occur in qualitative traits on the basis of frequency distribution. As result two clusters was obtained at linkage distance 25. Cluster-1 contains 39 lines while cluster-2 contains only 1 line. In protein profiling a total of 12 bands were observed in which 10 bands were polymorphic and two bands 1 and 9 were monomorphic. the genetic diversity on band 1 is 0.65%, band 2 (0.58%), band 3 and 4 (0.45%), band 5 (0.50), band 6 (0.55), band 7 (0.60), band 8 (0.28), band 9 (0.68), band 10 (0.75), band 11 (0.70), band 12 (0.65), these bands were further divided into three zone on the basis of molecular weight. Zone one contain four bands (band 12, 11, 10, 9), zone two contain four (band 8, 7, 6, 5), zone three also contain four bands (band 4, 3, 2, 1). Band 5 dominantly present in zone two bands 10 is dominantly present in zone one which show significant genetic diversity among barley genotypes, a dendrogram tree were also construct for protein bands. As result three clusters were obtained at linkage distance 25. Cluster-1 contains 16 genotypes cluster-2 contains only 14 genotype and cluster-3 contains 10 genotypes out up 40.

“…Additionally, when clustering and population structure analyses have been considered, the total genetic variation was higher within than between groups, and the groups were in general consistent with the geographical origin of the lines, except in a few cases. Mzid et al [ 64 ] assessed genetic diversity in a panel of 53 Lebanese barley landraces through the electrophoretic pattern of the seed storage proteins, hordeins. In this case, the absence of correlation between the genetic variability and the geographic origin of sample provenance was explained by the fact that Lebanon is a small country where seeds are easily exchanged between farmers’ communities in the different regions.…”

The renewed focus on cereal landraces is a response to some negative consequences of modern agriculture and conventional breeding which led to a reduction of genetic diversity. Cereal landraces are still cultivated on marginal lands due to their adaptability to unfavourable conditions, constituting an important source of genetic diversity usable in modern plant breeding to improve the adaptation to abiotic or biotic stresses, yield performance and quality traits in limiting environments. Traditional agricultural production systems have played an important role in the evolution and conservation of wide variability in gene pools within species. Today, on-farm and ex situ conservation in gene bank collections, together with data sharing among researchers and breeders, will greatly benefit cereal improvement. Many efforts are usually made to collect, organize and phenotypically and genotypically analyse cereal landrace collections, which also utilize genomic approaches. Their use in breeding programs based on genomic selection, and the discovery of beneficial untapped QTL/genes/alleles which could be introgressed into modern varieties by MAS, pyramiding or biotechnological tools, increase the potential for their better deployment and exploitation in breeding for a more sustainable agricultural production, particularly enhancing adaptation and productivity in stress-prone environments to cope with current climate changes.

A total of 198 exotic barley genotypes were collected from the Gene Bank of the Plant Genetic Resource Institute (PGRI), National Agriculture Research Center (NARC), Islamabad, Pakistan, for the assessment of genetic diversity based on morphological and seed storage proteins. Qualitative and quantitative traits were noted as per IPGRI, 1994 descriptor. Among the quantitative parameters, a high level of genetic variability index was noted in seeds per spike at 79.9% of coefficient of variance followed by biomass per plant which shows 37.4% variance, while minimum variance in quantitative traits was noted in days to germination at 5.4% followed by days to maturity at 3.1% with average mean genetic variation in all quantitative traits at 97.6%. Assay of total seed protein in these exotic accessions was analogue through polyacrylamide gel electrophoresis. A high level of variation was noted in loci (bands) B26 (0.98%) followed by B25 (0.89%), B24 (0.78%),B23 (0.69%) and B01 (0.52%). A similarly low level of variation was detected in B03 (0.16%) followed by B06 (0.18%), B13 (0.19%), B12 (0.21%), B11 (0.23%), B05 (0.24%), B07 (0.25%), B21 (0.34%), B20 (0.35%), B17 (0.39%). The results indicate that the mean value of variation in these accessions is 97.6%. Further assessments and exploration were suggested for these genotypes in multi-climatic zones to satisfy farmers’ need, breeders’ interest and malt-industrial requirements.
