Abstract:
... A number of different strategies have been utilized to introduce parthenocarpy into tomato commercial cultivars. In this study, we evaluated three segregating populations (F₂, F₃, and F₄) derived from conventional crossing between iaa9-3 mutant in Micro-Tom and an inbred pure tomato line V62. The mutation caused potato leaf style and high parthenocarpic fruit set ratio (nearly 90%). Introducing ia ...

Abstract:
... Fruit shape index (round shape) and seed size have important effects on pumpkin yield. To investigate these traits and to create the most desirable state, a cross was made between two pumpkin cultivars. This study aimed to estimate the main gene effects (additive, dominant and di-genic epistasis) and to determine the mode of inheritance for fruit shape and seed size by generation mean analysis.

Abstract:
... Papaya has a narrow genetic base concerning disease resistance, with few genetically distinct cultivars for planting in the world. Losses in crop production caused by fungal and viral diseases, added to the absence of resistant cultivars available to producers, have reduced the competitiveness of crops. Therefore, this study aimed to select promising individuals for resistance to phoma spot and bl ...
