Use horticulture technology of foliar fertilizer, inhibit shoot growth, and bag fruit to improve and stabilize quality of fruit harvested in summer. Research the optimal package of fruit to reduce chilling injury and enhance the quality of fruit to export trade. The objectives of the current project include multipurpose breeding, antioxidant ability assessment, and genotype-specific marker development in guava. Because of the demand for diversified cultivars, characteristics such as red flesh, climacteric fruit, and high antioxidant capacity in addition to seedlessness will be evaluated in breeding for new cultivars. The progeny produced by crossing, selfing, or open pollination and F2 populations established previously will be employed in trait evaluation and elite line selection. In addition, the fruits of these breeding materials will be used for analyses of antioxidant capacity and nitrite scavenging ability. In view of the common problem of low reproducibility in RAPD analysis for use in genotype identification, the work of converting polymorphic RAPD markers into more reliable sequence characterized amplified region (SCAR) markers will also continue in this project.
