Water-stress resistant in rapeseed cultivars is an efficient and productive approach to face the challenge of water shortage. Therefore, the current study regarding correlation analysis was carried out under water stress in order to identify the yield enhancing characters, which are evolving in high yielding rapeseed genotypes under water stress conditions. The experiment was conducted in a randomized complete block design with factorial arrangements having twenty rapeseed genotypes at Botanical Garden, Sindh Agriculture University Tandojam during the growing season of 2019-20. For the estimation of correlation, two treatments were used, such as, well-watered (WW) with four normal irrigations at several growth stages and water stress (WS) with only two irrigations, imposing at silique formation stage. The values of mean squares of genotypes, treatments and genotype × treatment interactions were differed significantly ( P ≤0.05) for many studied traits, signifying that breeding materials used in the present research has worth to be used in future rapeseed improvement programs. Most of the investigated characters exhibited positive and significant ( P ≤0.05) correlations with seed yield plant -1 under well-watered and water stress conditions, such as, plant height (WW= 0.60 ** ; WS= 0.61 ** ), branches plant -1 (WW= 0.51 ** ; WS= 0.46 ** ), silique plant -1 (WW= 0.49 ** ; WS= 0.33 ** ), seeds silique -1 (WW= 0.74 ** ; WS= 0.71 ** ), silique length (WW= 0.86 ** ; WS= 0.88 ** ), seed yield silique -1 (WW= 0.77 ** ; WS= 0.80 ** ), seed index (WW= 0.85 ** ; WS= 0.86 ** ), relative water content (WW= 0.60 ** ; WS= 0.61 ** ), chlorophyll (WW= 0.77 ** ; WS= 0.81 ** ) and oil content (WW= 0.51 ** ; WS= 0.55 ** ). Besides that, scientists and farmers can be used such characteristics as selection criteria to develop high-yielding rapeseed varieties water stress tolerant condition.","PeriodicalId":20855,"journal":{"name":"Pure and Applied Biology","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81690734","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 core idea of this study was to screen and identify maize genotypes for drought tolerance through morphological and molecular characterization for Balochistan region. In-vitro experiment was carried out using four maize genotypes namely Azam, Jalal, Edhi and Pahari that were investigated for drought stress tolerance at seedling stage. Completely randomized design (CRD) was used for current study. Maize seedlings were grown in growth chamber and after two-weeks of drought stress, samples were collected at different time periods. The morphological data showed that the root architecture of Jalal was significantly different from the remaining studied genotypes. These results were further strengthened and supported by the molecular analysis. For wet lab experiment, the DNA was extracted by Plant Mini Kit method and the presence/absence of drought tolerant gene was confirmed through the Polymerase Chain Reaction (PCR). The specifically designed primers for candidate orthologues were used to obtain the targeted PCR products. Furthermore, the results of PCR were confirmed through gel electrophoresis. The results of inter simple sequence repeats (ISSR) markers showed that only ISSR-838 was attached on Jalal while remaining genotypes did not showed any amplification of the products, that mean the Jalal genotype is more diverse from the other genotypes for drought stress tolerance. The obtained results of this study will be further utilized for the development of drought resistant maize variety and also used in other future breeding programs of Balochistan.","PeriodicalId":20855,"journal":{"name":"Pure and Applied Biology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88886732","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}
