Molecular characterization grouped them according to their varietal affiliations into five major clusters. Majority of basmati genotypes were clustered together. SSR markers detected a total of 83 alleles ranging from 2-4. The pairwise genetic similarity values among different genotypes ranged from 0.17 to 0.92 with an average of 0.48 indicating the presence of moderate genetic diversity among the genotypes analysed. The PIC values reflected the level of diversity and allelic frequency among the varieties which varied widely among SSR loci from 0.062 to 0.664. Two SSR markers namely, RM7173 and RM101 were identified as genotype specific, for genotype HPR 2761 and Vasumati, respectively. Two advanced breeding lines of basmati HPR 2852 and HPR 2855 were clustered together with their basmati parents in dendrogram indicating maximum recovery of basmati genotypes. The polymorphism detected among the genotypes will be helpful in selecting genetically diverse parents in the future breeding programme. The information generated will be used for advanced studies in germplasm, pureline selection and rice breeding in the future breeding programme.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123937905","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 data was further subjected to PCA (principal component analysis) and genotype by trait biplot analysis. The first 2 principal components accounted for 33.8% of total variation. Phenological traits and growing degree days had major contribution towards heat tolerance as indicated by principal component analysis. Correlation analysis revealed that grain yield was positively associated with biological yield and harvest index. Promising cultivars were identified for terminal heat tolerance that can be adapted for growing under late sown condition and further used for breeding improved climate resilient wheat cultivars and genomics study.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"32-33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132043434","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}

Breeding wheat cultivars with increased genetic potential can contribute to meet at least half of the desired production increases. In this context we have developed some advanced wheat lines in our breeding program, which aims to utilize the untapped variability. We assessed a set of 60 diverse lines along with four commercial check varieties for various agro-morphological traits, grain quality and yield based and also the adaptability using molecular markers. Significant genotypic differences were observed for most of the grain quality and agro-morphological traits recorded, including grain yield. We could identify lines which have significantly higher grain yield. The diversity analysis carried out using the DNA markers could explain the variability for different traits in this set. This set of genotypes is thus a very useful source as far as enhancing the yield levels. The lines developed through the conventional breeding program were based on crosses between elite breeding lines and specific donors and hence might resulted in higher yield potential.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131619862","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}

Barley is considered as an important food ingredient because of the presence of vital biochemical constituents viz. β-glucan, starch, amylose, protein etc. Barley is usually classified as hulless or hulled types (absence or presence of hull adhering to grain). Hulless barley needs negligible processing and preserves maximum of the endosperm and germ, which is once in a while lost during the time spent for dehulling. As a result, it is highly suitable for human utilization, as the entire grain can be specifically utilized to form a meal or processed into flour. Interest in the use of hulless barley as a food grain has expanded primarily due to its stated health benefits .The regular intake of hulless barley contributes to maintenance of normal blood cholesterol level, beneficial in preventing certain types of cancer like colon cancer and also provides better glucose and insulin responses. Hulless barley has high β-glucan content which helps in lowering of glycemic index and also causes the stimulation of bowel health. For this reason food industry is anxious about expanding the utilization of these cereals as nourishment fixings and henceforth more research is merited here.","PeriodicalId":183623,"journal":{"name":"Wheat and Barley Research","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132244601","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}

Presence of standard or commercial heterosis is essential for successful development of a hybrid cultivar. The discovery of heterosis and its exploitation in modern plant breeding programmes is one of the most important advances in plant improvement (Alghamdi, 2009). Although hybrid development in wheat could not achieve any success in the world but efforts are being made for development of CMS (Cytoplasmic Male Sterility) based hybrids in wheat for marginal land with half seed rate and in this direction, more than 50 diversified cytoplasmic male sterile (CMS) lines were developed in agronomic background of Indian wheat cultivars using backcross breeding at ICAR-IIWBR, Karnal (Singh et al., 2016). These new CMS lines were evaluated for male sterility and 12 CMS lines in agronomic background of DBW 17 (a promising cultivar of NWPZ were crossed with 3 fertility restorer lines (Res 5, Res 37 & Res 38) during 2016-17 crop season to develop 36 experimental hybrids.
