One of the major breeding objectives for watermelon (Citrullus lanatus [Thumb.] Matsum & Nakai) is improved fruit yield. High yielding genotypes have been identified, so we measured their stability for fruit yield and yield components over diverse environments. The objectives of this study were to (i) evaluate the yield of watermelon genotypes over years(More)
In a crop breeding program, multiple-location trials can be used to define target regions and mega-environments that, in turn, will help the breeder develop stable cultivars. In addition, locations can be chosen that are efficient for distinguishing among cultivars (genotypes) and that are good representatives of the target regions. The objectives of this(More)
The authors have presented an excellent study that provides the­ oretical and empirical justification for the use of the Newmark sliding-block method in estimating displacements of lateral spreads using residual strength values. The discussers believe that this is insightful work and will have a strong impact on research and practice, and would like to(More)
Lycopene is a naturally occurring red carotenoid compound that is found in watermelon. Lycopene has antioxidant properties. Lycopene content, sugar content and hollowheart resistance are subject to significant genotype×environment interaction (G×E), which makes breeding for these fruit quality traits difficult. The objectives of this study were to (i)(More)
