Abstract:
... Genetic relatedness and phenotype are important factors that govern the expression of heterosis in hybrid progeny of many cross-pollinating plant species. Since this relationship is important but not well understood in melon (Cucumis melo L.), one monoecious and two andromonoecious melon lines of diverse Chinese [Peoples Republic of China (PRC)] origin were crossed to the andromonoecious U.S. West ...

Abstract:
... Flowering time has biological and agricultural significance for crops. In Upland cotton (Gossypium hirsutum L.), photoperiodic sensitivity is a major obstacle in the utilization of primitive accessions in breeding programs. Quantitative trait loci (QTLs) analysis was conducted in two F₂ populations from the crosses between a day-neutral cultivar Deltapine 61 (DPL61) and two photoperiod sensitive G ...
