It was reported that whitefly response towards its hosts and their cultivars varies, and is mediated through various host-related factors. Considering the significance of leaf morphological characteristics in influencing the host–whitefly responses, the present investigation was conducted in screen-house conditions to study the prevailing variations in leaf morphological characteristics of soybean genotypes and their role in governing the adult whitefly attractiveness and oviposition preference. In the multiple-choice test, the whitefly population (eggs, nymphs and adults) was found to be lowest in moderately resistant genotypes (SL 1028 and SL 1074) compared to highly susceptible (DS 3105) and susceptible genotypes (SL 688, SL 958 and SL 1113). The foliar trichomes were characterized using scanning electron microscopy and leaf area, leaf lamina thickness and leaf shape data were acquired using standard procedures. To determine the factors involved in the resistance/susceptible responses towards whitefly, Pearson correlation was applied between the morphological characteristics and the whitefly population. The results show that the leaf area, trichome density, trichome length and trichome angle showed a significant positive correlation with the whitefly population, whereas leaf lamina thickness was negatively correlated. Thus, for developing whitefly-resistant germplasm, breeders should choose genotypes having narrow and thick leaves with sparse, short and flat trichomes.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135980435","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}

They are part of livestock biodiversity and this diversity has been threatened since the second half of the 20th century by their replacement with animals from specialized breeds. The multiple benefits of farming systems using local breeds – provision of goods, landscape and environmental management, and uses related to cultural and heritage dimensions – have long been recognized and used to argue for their conservation. However, the notion of ecosystem services is rarely used to analyze those benefits. This article presents a qualitative approach to the provision of ecosystem services by farming systems that use livestock biodiversity. Based on diverse case studies of breeds from several species, we propose an analytical framework that accounts for how a service is qualified, who is concerned by the services identified, the role of the breed in the process of service provision, and interactions between services. Finally, the framework considers the links between the provision of services and the management of the breeds. We discuss to what extent the notion of ecosystem services is useful in dealing with the multiple benefits from farming systems using local breeds.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88790452","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}

Gaertn.) is the fourth most important crop in Nepal having multiple benefits but is still neglected by mainstream research and development. The main option to boost its productivity is developing superior varieties through enhanced use of germplasm in breeding programmes. With the objective of enhancing utilization of landraces conserved ex situ, a total of 300 finger millet accessions collected from 54 districts were characterized in three hill locations of Nepal for two consecutive years (2017–2018). Nine qualitative and 17 quantitative traits were recorded, and combined mean data were subjected to multivariate analysis to assess agromorphological diversity. Shannon–Weaver diversity indices (H') showed high diversity (0.647–0.908) among the accessions for qualitative traits except for finger branching and spikelet shattering whereas high diversity (0.864–0.907) was observed for all quantitative traits. The first five principal components (PC) explained 61.8% of the total phenotypic variation with two PCs explaining 37.5% variation mainly due to flowering and maturity days, plant height, flag leaf length, grain and straw yield, ear weight, ear exsertion and number of fingers per head. Genotypes were grouped into four clusters with 16, 66, 107 and 111 accessions based on quantitative traits. The correlation between the traits indicated that accessions with early flowering, tall plants, long leaves, high tillers, large ears and bold grains could be given priority for further evaluation in multiple locations. Potential landraces identified for each trait could either be deployed to wider areas as varieties or used as trait donors in finger millet breeding.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"217 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79668466","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}

Frequency, general linear model, and multivariate analysis procedures of Statistical Analysis Software (SAS 9.0) were used to analyze the data. The morphological similarities among the cattle populations from Tulo, Jarso, and Fedis districts confirm the presence of a unique cattle breed which was previously referred to as Harar cattle. The same was observed for the cattle populations from Jigjiga and Kebri Beyah districts which were previously referred to as Ogaden cattle. The Harar cattle are characterized by their forward-oriented, widely spaced, and medium-length horns while the Ogaden cattle possess upright-oriented, narrowly spaced short horns. The majority of the Ogaden cattle had gray body color while the Harar cattle possess multiple body colors where red and its combination with white and black colors are observed frequently. Most of the morphometric measurement values were higher for the oxen, while the cows had longer horns. Moreover, Ogaden cattle had higher morphometric measurement values than the Harar cattle. According to the multivariate analysis results the cattle populations in the study area were separated into two breeds; the Harar and Ogaden. However, these results only showed the phenotypic differences which might not necessarily be due to genetic differences. Therefore, further genetic characterization is recommended to understand their level of relationships which in turn helps to design conservation and breeding programs.

To identify if distinctive Saragolla landraces are present in Abruzzo and with a view to registering them as Conservation Varieties in the Abruzzo Regional Register of Genetic Resources, a quantitative botanical characterization of 11 farm-saved seed samples from Abruzzo and a previously defined Saragolla landrace from Puglia was performed. All twelve samples were grown for two years at the CREA-CI field station in Foggia, Puglia (Italy), and were morphologically characterized according to the criteria used by the botanist Johan Percival in 1921. In the 12 samples, we identified 9 taxonomically different botanical types, the most frequent of which were the italicum (32%), found in every population from Abruzzo. The leucurum and the affine were the main components of the previously defined Saragolla from Puglia. Results of the multivariate analysis indicated that the samples collected from farms in Abruzzo are more similar to each other than to the landrace of Saragolla from Puglia and support the registration of a specific Saragolla landrace for the Abruzzo region. The diachronic comparison of the botanical diversity of the currently cultivated Saragolla, with that observed in Sicily and Algeria at the beginning of 1900, suggests that a high degree of genetic diversity still exists in the 11 Saragolla populations from the Abruzzo Region.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530693","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}

Pollen quantity and grain size (≈quality) are affected by the environment, but are also heritable traits of interest for breeding. Florets from public inbred B-lines (maintainer) and R-lines (restorer) were used to evaluate pollen quantity and quality, test for trait correlations and determine if line development has changed pollen traits. Pollen quantity (≈25,000–67,000 grains per floret) and diameter (≈30–37 μm) were similar to previous reports and values of each parameter were correlated across years. Pollen quantity per floret was positively correlated with floret size (area; mm 2 ) but floret sizes and pollen quantity were unrelated to pollen grain size. Groups of lines released relatively early (1968–1986) or late (1988–2006) did not differ in pollen quantity or size, and male (R-line) parents did not produce larger grains. The strong, positive correlation between floret size and pollen quantity reveals a possible trade-off because wild bees generally prefer sunflowers with shallower florets. The apparent lack of change in pollen quantity or pollen grain size over time (and lack of increased pollen size in R-lines relative to B-lines) suggests that the quantity and quality of pollen may not be limiting factors in the success of inbred lines or resulting hybrids. Though sunflower lines with larger florets contain more pollen, additional variation in pollen visible on sunflower heads may relate to the timing or completeness of pollen extrusion from anther tubes.","PeriodicalId":20188,"journal":{"name":"Plant Genetic Resources","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135144240","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}
