  Development of new inbred lines more adapted to the adverse environmental conditions by selection of agro-morphological and biochemical traits in pumpkin, Descrição: Pumpkin (Cucurbita moschata L.) is one of the important snacks for consumers in Egypt in which its fruits are consumed in natura or in their processed forms as purees, jams, juices, nectars, fruit cocktails, and alcoholic beverages (Veronezi and Jorge, 2018). In addition to the flesh consumption, ?Pumpkins? have the largest seeds in the species, which are commonly consumed. Due to the lack of registered cultivars and certified seed production in Egypt, development of new cultivars on confectionery pumpkin, is urgent need. In this regard, establishment of new breeding program beside the current efforts, that is expected to start in 2020 shall enhance and support our objectives as a work in different background of cultures. To develop new cultivars of pumpkin, the present proposal illustrating an overview of the efforts that shall be done through successive cycles of selection. Hence, selecting and selfing will be applied to develop new inbred lines of promising genotypes of pumpkin. Also, the analysis of the genetic performance for multiple morphological, yield and fruit traits as follows; as vine length, number of branches per vine, number of leaves per vine, number of fruits per vine, fruit weight, yield, fruit diameter, fruit length, fruit thickness and cavity length and diameter, fruit total soluble solids, fruit pH, fruit vitamin c and fruit vitamin A would be accomplished for selection and isolation of distinacted lines of pumpkin. The genetic materials will collect from different part of Egypt and selection will apply based on the single seed descent method. Selected plants will self each generation based on morphological, agronomical and biochemical properties in order to develop new pumpkin cultivars and to produce hybrids. After final evaluation of homogeneity in third year, some of them will send to registration, The lack of certified seed and high yielding varieties are the most important problems in confectionery pumpkin production in Egypt. Therefore, this research will cover of breeding studies and yield trials to develop confectionery pumpkin lines and hybrids in Egypt in between 2020 to 2023. In recent years in Egypt, there has been an increase in interest in pumpkin farming. When the last decade period was examined, there was a 133% increase in pumpkin and a 35% increase in the production amount. The main reasons for low yield in the country are; because of the wrong selection of the varieties belonging to the region and the difficulty in obtaining stable varieties. Egypt is one of the important diversity regions for this crop, because of their adaptation to diverse ecological conditions because of both natural selection and the selection by farmers. So, development of cultivars suitable for a specific region also is a key issue in this crop due to the diversity in climatic and environmental condition that pumpkin growing under these regions. So, the main goal of current proposal is to develop new, unique and superior pumpkin lines that could be integrated as new cultivars or in hybrid production national system distincted by its stablilty and high yielding capacity. While increasing cultural awareness of farmers and consumers about the important use of certified seeds, supporting search extension with realistic ideas to find solutions and answer questions among of the current porject objectivs. Finally, strengthening relations between the host institute and other organizations through promotion of the exchange of experiences and knowledge.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Ahmed Youssef Abdelnabi Mohamed Elsayed - Coordenador / Abeer I Shabana - Integrante / Hassna Ahmed Ismail - Integrante / HABIBA, REHAB - Integrante / Alla Eldin hassan Elnahry - Integrante., Financiador(es): Ministry of Agriculture and Land Reclamation - Auxílio financeiro.

  Identification Of Potential Genotypes And Inheritance Pattern For Developing Thermo-Tolerant Tomato Cultivars, Descrição: In Egypt, a large number of tomato varieties are grown. Most of them lost their potential due to genetic deterioration, biotic and abiotic factors. Hence, Heat stress is the most important determinants of the continuity of the production of the tomato in the late summer period where the fresh market tomato prices increase about 400% to 500% every year with inferior fruit quality. Hence, development of tomato varieties with high fruit set suitable for planting in the late summer season is the main objective of our proposal. In addition, due to the wide spread of Tomato Yellow Leaf Curl Virus especially in this period of year, looking for resistant sources will help in the reducing of agrotoxins that are used extensively.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Especialização: (2) / Mestrado acadêmico: (1) . , Integrantes: Ahmed Youssef Abdelnabi Mohamed Elsayed - Coordenador / Ghobary, H.

  Enhancement the adaptive capacity against the negative impacts of salinity, Descrição: Egypt suffers from significant salinity problems as due to irrigation with low quality water and poor drainage systems where 33% of the cultivated land is already salinized. Overcoming salt stress is a main issue in these regions to secure crop productivity. Processed waste water may provide an alternative water source for irrigation, but needs to be analyzed for contaminants before application in order to avoid environmental pollution. Development of high salt tolerance cultivars are important demand for cultivation expansion in Egypt. The main objective of the project is to enhance the local adaptive capacity to minimize the risks and impacts of salinity, and prevent and limit soil degradation by development genetically improved cultivars. In this proposal, a genetic improvement program based on hybridization and selection will be elaborated on salinity tolerance in tomato and eggplant by numerous research groups operating at least three different institutions are described. A set of advanced inbred lines of F5 generation were derived previously from different F2 populations selected for diverse favorable traits including heat tolerance will be integrated in the current project. In addition, a collection of the National Gene Bank will provide a set of accessions characterized and will identify the genetic materials that have different levels of salt tolerance. Reduce dependency on imported seeds by generation national varieties competent with high productivity under the local conditions of Egypt, is main project benefits. In addition, research stimulation and enhancement of scientific production; obtaining advanced inbred lines with diverse characters that could be used in further investigations; maximizing the utilization of genetic resources through improvement of conservation conditions of the germplasm and the advanced bred lines finally, enhancement administration activities through well-investment for human and financial resources are among the expected outputs of our proposal.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Ahmed Youssef Abdelnabi Mohamed Elsayed - Coordenador / Hamdinho M I Ahmed - Integrante / Ashraf Hamed Abd Allah - Integrante / Hassna Ahmed Ismail - Integrante., Financiador(es): Ministry for Agriculture and Land Reclamation - Bolsa.
