Determining and improving drought-tolerant cultivars is a major goal of plant breeding to face climate change. The productivity faba bean in Egypt affected by abiotic stresses, especially drought stress. This study evaluated eight Egyptian for tolerance under three soil water regimes consisting well-watered (100% field capacity), moderate stress (50% severe (25% capacity) pots greenhouse condit...

This paper presents a new method and a constraint-based objective function to solve two problems related to the design of optical telecommunication networks, namely the Synchronous Optical Network Ring Assignment Problem (SRAP) and the Intra-ring Synchronous Optical Network Design Problem (IDP). These network topology problems can be represented as a graph partitioning with capacity constraints...

Genetic maps for two pear cultivars ‘Red Bartlett’ (Pyrus communis L.) and ‘Nanguo pear’ (Pyrus ussuriensis Maxim.) were constructed using SRAP molecular markers. The mapping population consists of 74 F1 individuals derived from the cross of a cultivar ‘Red Bartlett’ with good fruit quality as the female parent and a cultivar ‘Nanguopear’ with good cold tolerance as the male parent. Linkage map...
