Pepino (Solanum muricatum Aiton), also known as melon-pear, is a vegetatively propagated vegetable crop grown for its juicy and aromatic fruit. Great variation in fruit weight, shape, and color can be found among cultivars of pepino (Anderson et al., 1996; Heiser, 1985). Despite being an important crop in Pre-Columbian times in the Andean region, it has not achieved the same relevance as other ...

Stem rust along with foliar diseases is a harmful pathogen causing strong yield reduction worldwide. Resistant cultivars provide efficient way for wheat growers to avoid yield losses. In our study, 200 wheat cultivars registered in Hungary in the past twenty five years, were investigated using molecular markers. A significant part of the cultivars carried the 1BL.1RS translocation, the source o...

Background The history of the world citrus industry is marked by a series of diseases caused by different etiologic agents. Several of them are characterized as biotrophic pathogens like Xanthomonas citri subsp. citri, three Candidatus Liberibacter spp and Citrus leprosis virus C (CiLV-C). In plant-pathogen interactions, the role of salicylic acid (SA) in activating defense related genes is wel...

Sweet potato (Ipomoea batatas L.) is the seventh most important food crop due to its distinct advantages, such as adaptability to different environmental conditions and high nutritional value. Assessing the genetic diversity of this important crop is necessary due to the constant increase of demand for food and the need for conservation of agricultural and genetic resources. In Puerto Rico (PR)...

Salt stress strongly affects on plant growth and development, especially maize plant, which is reported as a salt sensitive species. The salt tolerant identification in the large genetic resources and breeding population is a profitable research topic for solving the salinity problem. Two maize cultivars, viz., sweet (Zea mays L. cv. Saccharata) and waxy (Z. mays L. cv. Ceratina) seedlings were...

Farmers in many regions of the world grow a horticultural or grain crop between sugarcane (a complex hybrid of Saccharum spp.) cycles. This additional crop often requires higher amounts of P or K fertilizers than does sugarcane. Some sugarcane growers in Florida precede 2to 5-year cycles of sugarcane with one crop of spring-harvested sweet corn (Zea mays L.). A disadvantage perceived with this ...

most sweet cherry cultivars are as found as self-incompatible and therefore for commercial fruit production, compatible pollinizers are needed. controlled pollination and microscopic examination of pollen tube growth in the style are two classical methods for determination of compatible and incompatible pollen donor cultivars. this experiment was carried out to explore the compatibility of ‘zar...

abstract evaluation of pomological characteristics can be useful in selection of best cultivars for commercial purposes. during this project, seven cultivars of sweet cherry including five cultivars from hungary (‘stella’, ‘sunburst’, ‘germesdorf’, ‘summit’ and ‘subima’) and two control cultivars (‘cillage blamarka’ and ‘siahmashad’) were studied by completely rondomized blocks design with thre...

Early storage root bulking (ESRB) in cassava has increasingly become important in the national cassava breeding programmes in Africa. To assess farmers' perceptions on ESRB in cassava and identify their cultivar selection criteria, a study was conducted in east and central Uganda. One hundred and twenty cassava farmers were sampled and interviewed following structured questionnaires, and their ...
