♦Improving of seeds/seedlings propagation and production techniques of tropical crops and related studies
▲To produce quality cacao seedlings, selection of high yield cacao plants and establishment of grafting propagation models were conducted. Provide industry promotion and planting.
▲Cocoa fruit looks colorful
▲Established cocoa nursery technology to enhance consistent germination rate and to reduce contamination
▲For improving the quality of papaya seedlings, we set up roof-vent and side-roller with the intelligent environment control system and renovated the punching net to make better environment of the green house.
▲When Semi-lignification period of papaya seedling, removing the top shoots will get the best number of branches.
♦Development of tropical crop variety character verification technology and related businesses for variety verification
1.Test method and breed character table
▲The center has carried out the development of the new succulent plant genus Versicolor cultivar verification technology. It has collected and preserved 26 varieties of Graptopetalum, cultivated and observed its growth and morphological characteristics, and completed the first draft of a 35-character survey form.
2.Crown of thorns variety test
▲There are 2 new varieties of the unicorn flower 'Cuiyu' and 'Red Dragon' that have undergone substantial inspection.
♦Breeding for gynoecious cucumber.
▲Selection of net house grown cucumber hybrid lines to breed the cultivars with characteristics of heat-tolerant, outstanding gynoecious and year-round production.
▲The outstanding gynoecious and parthenocarpic cucumber hybrid line.
♦Breeding for disease resistance and high quality eggplant.
▲Field selection for long and straight fruit and for pest-tolerant hybrid lines of eggplant.
▲The high quality eggplant hybrid line with glossy and deep purple skin and elongated shape.
▲Evaluation and field selection of eggplant rootstock lines for bacterial wilt resistance.
♦Selection of high-quality papaya varieties
▲Seeds/seedlings of all hermaphrodite papaya lines need only one seed for each plant hole and obtain 100% ermaphrodite papaya trees. It could save seedling cost and do the cultivation management easily.
♦Seeds/seedlings production of agricultural crops and horticultural crops
▲Field management, emasculation and pollination for producing high quality tomato hybrid seeds.
▲In order to increase the genetic purity of tomato hybrid seeds, we cut off partial sepals as pollination mark to avoiding harvesting of self-pollinated fruits.
▲Tomato harvesting requires hybrid fruits with markings
▲Produce superior maize hybrid seeds and conduct field management operations such as detasseling and pollination to provide excellent seeds for farmers to plant.
▲Hard corn ear
♦Healthy seeds (seedlings) production
▲To establish a fine nursery environment, the center to effectively isolate wimbledon, nurturing horticultural crops healthy seedlings.
▲To establish the healthy seedlings production processes of no specific pests and diseases papaya and cucurbits.
▲Melon health seed production
▲Value-added application of papaya seed by-products: established the technique of papaya pectin extraction.
