TL;DR: The technology for using these markers in marker-assisted selection (MAS) has been greatly improved and the ability to use MAS to pyramid genes will make this technology an essential tool for legume breeders.
Abstract: Numerous molecular markers, linked with traits of agronomic importance in the food legumes, pea, chickpea and lentil, have been identified Microsatellite markers are being developed and mapped in a collaborative effort between the International Center for Agricultural Research in the Dry Areas (ICARDA) and the University of Frankfurt to overcome the relatively low amount of information that can be derived from the widely used dominant markers in chickpea Besides mapping and identifying host plant resistance, efforts are being made to characterize the pathogen populations Once host plant resistance has been identified and mapped, it will be feasible to deploy the relevant resistance genes when shifts occur in the pathogen population The technology for using these markers in marker-assisted selection (MAS) has been greatly improved The ability to use MAS to pyramid genes will make this technology an essential tool for legume breeders

TL;DR: This poster presents a probabilistic assessment of the phytochemical properties of Black-winged Pratincole, a type of Maize, which has shown promise as a feedstock for wheat and barley growers and has shown the potential for use as a raw material for other crops.

TL;DR: To accomplish this objective, cost analyses and genetic gain estimations were performed for four rice breeding scenarios: conventional and marker-assisted selection, with and without rapid generation advance, and a cost index reflecting the breeding efficiency was developed.
Abstract: Plant breeding for the generation of cultivars adapted to local conditions has been an important and strategic concern of developing countries with agriculture-based economies. Considering economic constraints, breeders must improve genetic gain to increase the delivery of better cultivars with lower costs, through the implementation of molecular breeding and rapid generation advance. The aim of this work is to assess the actual economic impact of the implementation of these technologies on genetic gain for yield, rice blast disease resistance, and grain amylose content in a conventional rice breeding program. This analysis is intended as a case study of public breeding programs in developing countries. To accomplish this objective, cost analyses and genetic gain estimations were performed for four rice breeding scenarios: conventional and marker-assisted selection, with and without rapid generation advance. These estimations were then used to develop a cost index reflecting the breeding efficiency. The most efficient method was found to depend on the objective trait considered. For yield, there are small variations in genetic gain, but in terms of costs, the application of technology increases the breeding efficiency. For rice blast resistance, marker-assisted selection is not an efficient option when not using rapid generation advance. Conversely, the efficiency of marker-assisted selection increases when using rapid generation advance. For grain amylose content, the greatest effect on genetic gain is obtained when using marker-assisted selection. Rapid generation advance always increases the breeding efficiency. The use of new technological tools is recommended in terms of the cost–benefit function.
