In this review, we address key questions related to the diversity of BW pathogens, susceptible TAV hosts, distribution, incidence, breeding strategies, sources of resistance, and gaps in the development of resistant TAV varieties in Africa. We also discuss the potential of multiomics integration to enhance our understanding of the host plant defense system against BW in Solanaceae crops. We curated BW strain databases obtained from several online platforms, representing a total of 948 BW strains. Using a refined database, we highlighted the diversity of RSSC and TAV crops affected by RSSC in different regions of Africa. Out of 29 species documented to be affected by BW in Africa, ten are TAV, including widely consumed TAV such as Amaranths and nightshades. In addition, phylotypes I and III are reported to affect TAV, and the incidence can reach up to 72.4% in farmers’ fields. An overview of the first reports revealed that the disease has become a serious threat to TAV in the past decade. Finally, this review proposes a schematic map of possible avenues for successful breeding of BW-resistant TAV using Gboma eggplant as a case study.","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it can be challenging to determine the sex of long-lived plants with long generation times. This is true for Cycas revoluta, which produces toxic seeds in female plants, leading to a preference for male plants in public green spaces. In this study we aim to identify a morphological trait that can be used to distinguish between the sexes in C. revoluta at a very early stage of plant growth. We sampled C. revoluta seedlings/plantlets at three different early growth stages and identified the sex of individuals by PCR amplification of a male-specific molecular marker. On the same plants, we measured morphological traits, including the distance between leaflets on the leaf rachis, perimeter, area, number of indents, and leaf complexity, and evaluated their correlation with the sex of the individuals. Among all measured traits, the medium distance between leaflets on the leaf rachis was found to be a sexually dimorphic morphological trait in Cycas plantlets in all three growth stages. In particular, the distance between leaflets on the leaf rachis in the upper part of the leaf in the first stage revealed no overlap between the sexes. Whenever available, morphological traits for sex differentiation in greenhouses and plant nurseries can represent a rapid and economic tool when coupled with automatized image recognition systems.","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification of molecular markers associated with oil quality traits may aid in genotype selection in breeding efforts of safflower. To determine the genetic basis of seed oil, oleic acid, and linoleic acid content in safflower seeds, a recombinant inbred population was developed from a cross between Goldasht (low oleic line) and Mex 22–191 (high oleic line) by individual self-pollinated plants in each generation (from F2 to F9). Fatty acid components were detected by gas chromatography and subsequently analyzed by QTL analysis. The high variability in fatty acid composition was demonstrated and the first high-oleic safflower genotype was generated. A new linkage map with 69 AFLP and 45 ISSR polymorphic markers was made, covering 1472,441 cM of the safflower genome. A total of 63 individual QTLs and 238 epistatic QTLs, related to oil quality, were detected in 14 genomic regions. Some major QTLs with phenotypic variation greater than 10% were identified for the measured traits. These results demonstrate that major QTL may play an important role in increase the oleic acid of the genetic material used. Furthermore, the larger number of minor QTLs and epistatic QTLs, both of which have additive effects, indicates that the expression of these traits is also influenced by interactions between multiple genes. Our results provide additional genetic resources that can be used to precisely breed these traits in the future.","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current legal frameworks in seed systems and variety handling predominantly serve the interests of seed companies, breeders, and extension officials, with limited consideration for the needs and preferences of farmers. This results in farmer’s varieties, characterized by their high genetic variation, as well as cultivar mixtures and evolutionary populations, receiving limited support within the policy framework. These broad genetic base cultivars have been cultivated and preserved by farmers for generations and exhibit resilience to diverse environmental conditions. The formal seed system, which has gained prominence, has separated farmers from a crucial aspect of their agricultural heritage. It is now managed by government offices and private seed companies, necessitating financial contributions from farmers to participate in the seed system. To encourage the cultivation of site-specific varieties with substantial genetic diversity, there is a need to promote these varieties, whether registered or unregistered, through a legal framework that encompasses all agricultural produces, not solely seeds. Such a framework acknowledges the capacity of farmers to independently maintain and cultivate their seeds, contributing to the preservation of genetic diversity and sustainable agriculture.","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Another factor is the use of different reference genomes from other species to perform SNP calling, which could make it possible to explore variability in interspecific crosses comprehensively. Late leaf rust is a disease caused by the pathogen Acculeastrum americanum, and there are reports on genetic resistance in Rubus occidentalis, which leads to the need for interspecific hybridizations, aiming to combine the fruit quality of R. idaeus with the resistance of R. occidentalis.

This study aimed to identify stable genotypes with high forage yields and key yield traits for sorghum breeding programs. Ninety-five forage sorghum lines were evaluated under five distinct climatic conditions over two years (2020–2021), revealing significant genotype × environment interaction (GEI) effects for 14 agronomic traits. Two BLUP-based mixed model stability methods, weight average absolute score based on BLUP (WAASB) and the multi-trait stability index (MTSI), were employed for stability analysis. Three genotypes, G90 (424B), G80 (382B) and G3 (349B) were identified stable and high yielding for forage yield based on WAASB based methods. The MTSI, a novel simultaneous selection index, effectively selected genotypes based on multiple agro-morphological traits, except for the leaf-to-stem ratio. Genotypes G81, G90, G80, and G89 were identified as desirable based on the MTSI. The strength and weakness plot is highlighted as a valuable graphical tool for identifying and selecting genotypes based on trait strengths and weaknesses. Among these, G90 (424B) and G80 (382B) stood out as superior, excelling in both forage yield and early maturity, as determined by WAASB based methods and MTSI method. These genotypes warrant further comprehensive investigation across diverse environments and show significant potential for future breeding programs.","PeriodicalId":11803,"journal":{"name":"Euphytica","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
