The direct germination test destroys the seed. Viability evaluation by nondestructive tests allows the saving of seeds for storage and future use. However, predictive values of most nondestructive tests have not been adequately determined. This study investigated performance parameters and optimized assay conditions for a nondestructive colorimetric resazurin seed-viability test of flax seeds (Linum usitatissimum L.). In this study, 800 seeds were tested by resazurin test before germination. Optimization of resazurin test conditions and cutoff value was determined via a “receiver operating characteristic curve” analysis. We found that the optimal incubation time was 2 h. We proposed to measure sample absorption at 595 nm for better seed-viability estimation by resazurin test due to spectral properties of dye. We improved sensitivity of the resazurin test by using measurements adjusted to blank absorption at 595 nm (sensitivity 91%) or to sample absorption at 490 nm (sensitivity 95% versus 81% before corrections). The resazurin test reliably predicted germinable seeds in 72–73% cases and ungerminable seeds in 92–95% cases, with a sensitivity of 91–95% and a specificity of 71–74%. Therefore, the easy and low-cost resazurin test exhibited analytical performance similar to more expensive instrumental tests and can be suitable for nondestructive seed-viability estimation.","PeriodicalId":15468,"journal":{"name":"Journal of Crop Improvement","volume":"37 1","pages":"821 - 833"},"PeriodicalIF":1.3,"publicationDate":"2023-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44537539","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}

Development of safe, and efficient biocontrol measures is important in the management of the disease. In this study, incidence of fusarium wilt of tomato in four agricultural zones of Oyo State was established through purposive sampling, and the abundance, and in vitro-biocontrol potential of Bacillus endophytes were determined. Strains of F. oxysporum and Bacillus endophytes were isolated from tomato plants collected from 21 farms. In vitro-inhibition potential of endophytes was determined through a modified, dual-culture assay, involving six endophytes, and carbendazim (fungicide), set up in a completely randomized design. Using a rating-scale of 0–9, the highest wilt severity (6.67) and incidence (39.30%) were observed on Akinware farm in Ibadan/Ibarapa agricultural zone of Oyo State. Fusarium oxysporum IB3q caused severe wilt symptoms, including leaf chlorosis, necrosis, vascular discoloration, and wilt, on infected Alausa and Ibadan-local tomato varieties. Thirty-nine strains of Bacillus endophytes were isolated from the tissues of healthy tomato plants. Six of the isolated Bacillus endophytes inhibited F. oxysporum. Bacillus amyloliquefaciens Sa08 and B. subtilis Og04 had inhibitory zones of 15.67 and 19.43 mm, respectively, against F. oxysporum, and caused hyphal disintegration of the pathogen. They produced cell wall-degrading enzymes, with relative activities ranging from 0.87 to 5.04. Based on their in vitro-inhibition potential, B. amyloliquefaciens Sa08 and B. subtilis Og04 should be deployed, as prospective biocontrol measures against seed-borne fusarium pathogens and fusarium wilt on tomato plants.","PeriodicalId":15468,"journal":{"name":"Journal of Crop Improvement","volume":"37 1","pages":"796 - 820"},"PeriodicalIF":1.3,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43419652","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}

However, the yields are low due to the diseases like anthracnose caused by Colletotrichum lindemunthianum and Pythium root rots. The study, therefore, sought to screen Kenyan common bean genotypes for anthracnose and Pythium resistance and to improve the resistance of local landraces to the two diseases. Local landraces and commercial cultivars were screened for resistance under greenhouse conditions for Pythium and in vitro for anthracnose. The results showed that majority of the landraces were moderately resistant to anthracnose and Pythium root rot. The study further utilized molecular markers linked to anthracnose and Pythium resistance, respectively, to determine their potential to detect specific resistance genes among the test genotypes. None of the markers amplified the test genotypes except the control genotypes pointing toward different resistance genes. Further, cultivars G2333 and KK8 were used as donor parents for anthracnose and Pythium resistance, respectively, in a marker-assisted backcross breeding program involving three high-yielding farmer-preferred landraces. A number of lines were developed that carry both resistance genes. These lines can be advanced for release as new cultivars to enhance common bean production in Kenya.","PeriodicalId":15468,"journal":{"name":"Journal of Crop Improvement","volume":"37 1","pages":"853 - 873"},"PeriodicalIF":1.3,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49433460","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}
