The release of rice cultivars with improved performance in saline environments is reliant on an understanding of genetic control of traits of plant exposed to salinity. This is vital in the choice of methods of generation advancement and evaluation. Thus, this study aims to know the genetic mechanism controlling salt tolerance in rice in Niger. One hundred and twenty F3 families derived from a full diallel cross of four parents including two tolerant and two susceptible genotypes were evaluated in farmer’s fields affected with high salt levels in two sites. The experimental design was 25×5 alpha lattice with 3 replications. Data on the duration, height, tiller number, panicle number, panicle weight, grain weight and yield were recorded. The intra-class correlation, heritability and gene action were estimated. Additive effects for tiller number, panicle number and panicle weight, additive maternal effects and partial dominance effects for height and duration were observed. The heritability was high and varied according to the site and the common parent.","PeriodicalId":356916,"journal":{"name":"International Journal of Plant Breeding and Genetics","volume":"171 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":"114407778","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 treatment consisted of three local cultivars namely Ryiom, Longat and Bebot laid out in a Randomized Complete Block Design (RCBD) with four replications. Results obtained indicated that Livingstone potato cultivars produced flowers from 158-215 Days after Planting (DAP). The number of branches, nodes, flowers and inflorescences per plant were significantly higher in Longat (p<0.05) than in Ryiom, while cultivar Bebot maintained an intermediary position in most parameters tested. Flowers dried up without fruiting or seed-setting in all cultivars probably because of the interplay of genetic and environmental factors.

In order to target the breeding program to processing end-use, the variability, location performance, Genotype-by-Environment Interaction (GEI), heritability estimates and relationships among important root processing traits among elite sweetpotato lines were studied in two locations. The genotypes exhibited significant (p<0.05) genotypic variability at each location for dry matter, starch content, flour content and fresh root peel-loss. The combined location analyses also showed that the expression of the traits was under the influence of genotype, environment and GEI. At Makurdi, starch content ranged 14.02-20.53%, while the range of dry matter, flour content and peel-loss were 20.48-37.73, 18.95-31.00 and 11.69-28.40%, respectively. At Umudike, starch was 17.58-23.00%, dry matter was 24.16-34.17%, flour content was 21.34-32.32% and peel-loss was 18.17-24.01%. Correlation study showed that dry matter was moderately correlated to starch (r = 0.53 at Makurdi and r = 0.52 at Umudike) and flour content (r = 0.79 at Makurdi and r = 0.76 at Umudike). Genotypes and traits biplot revealed that NRSP/05/1B, Ex-Igbariam and CIP 440163 largely influenced dry matter, while elevated flour content and peel-loss were related to Ex-Igbariam, CIP 440163 and TIS 87/0087. For heritability study, all the traits showed moderate to high heritability (broadsense) in each location and across locations. This work shows how to identify genotypes with desirable processing traits for release as new varieties. It also enhances the selection of new parent lines for developing new population for processing end-use.","PeriodicalId":356916,"journal":{"name":"International Journal of Plant Breeding and Genetics","volume":"41 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":"124145603","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}
