Sorghum improvement can be achieved by the utilization of the wide range of diversity existing in sorghum, which can lead to improvement of people’s sustainable livelihoods, agricultural productivity and economic development. Methodology: The performance of 19 grain sorghum (Sorghum bicolor L.) genotypes was assessed under water stress conditions using agro morphological and Inter Simple Sequence Repeats (ISSRs) markers. Two field experiments were executed during the summers of 2012 and 2013 at Shambat Experimental Farm, Sudan. A split-plot design with three replications were used to layout the field experiment. The sorghum genotypes were evaluated in the field under normal irrigation and water stress conditions. Data was collected to determine genotypic variability among the grain sorghum genotypes and to estimate the phenotypic correlation coefficients between different traits. In addition, the genetic diversity of the genotypes was determined by ISSRs. Results: The results showed that, drought stress caused significant reduction in most of the studied characters. Significant differences among the genotypes were found for all characters studied. The sorghum genotypes showed differential yield response to drought stress. High grain yield (t haG1) was exhibited by genotypes HSD7511 and HSD8849 which gave 2.3 and 3.7 t haG1, respectively. Grain yield (t haG1) was significantly and positively correlated with grain yield per plant and other yield components. However, it had no significance and negative association with plant height and days to maturity. Based on DNA markers analysis (ISSR), high level of polymorphism was detected among the 19 sorghum genotypes. Conclusion: From the 19 grain sorghum, accessions HSD7511 and HSD8849 gave the highest yield under drought stress. Drought stress affected significantly yield and yield components than the vegetative growth. The ISSR technique was efficient in determining the genetic diversity among the 19 sorghum genotypes and thus can be exploited further to establish consistent heterotic group between sorghum genotypes.","PeriodicalId":356916,"journal":{"name":"International Journal of Plant Breeding and Genetics","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126709905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of variance analysis showed the significance of environmental variance compared to the genotype and GE interaction variances. Polygon view of GGE biplot revealed that X7 (Acc. 208768) was the genotype with the highest seed yield in five out of six environments. The Average Environment Coordinate (AEC) biplot showed that X7 (Acc. 208768) with the highest mean yield was a highly stable genotype as it was positioned close to the AEC abscissa. The biplot of comparison of the sunflower genotypes with the ideal genotype revealed that X7 (Acc. 208768) was the closest genotype to the ideal cultivar. Therefore, this genotype seems to be widely adapted across several environments and is released as an open pollinated variety for wider production in Western Amhara and similar agro ecologies.","PeriodicalId":356916,"journal":{"name":"International Journal of Plant Breeding and Genetics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129177225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to determine the interrelationship of the genotypes and their genetic divergence. The experiment was laid out in randomized complete block design with three replications. The thirteen sesame genotypes were grouped into four clusters based on the similarity of their agronomic traits and the dendrogram showed that clusters I, II, III and IV had 9, 1, 1 and 2 number of genotypes and the highest grain yield (918.1 kg haG1) as well as highest oil content (55.1%) was observed in cluster III. The Mahalanobis’s (D2) distance, genetic divergence, among the clusters were statistically significant and the highest genetic divergence was observed between clusters II and III (D2 = 7425.5), whereas, the lowest distance was found between clusters I and III (D2 = 179.64). Eight Principal Components (PCs) were extracted from the eight agronomic traits of sesame and the first three PCs accounted for 88.49% of the total variance (45.05, 28.25 and 15.20% for PC1, PC2 and PC3, respectively) and these three PCs were considered as significant. G1 and G4 were highly associated with traits such as grain yield, oil content, length of capsule bearing zone and number of capsules and G12 and G13 were relatively better yielding genotypes. G2 that aligned with days to maturity confirms its delaying character in maturity.","PeriodicalId":356916,"journal":{"name":"International Journal of Plant Breeding and Genetics","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129552217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
