Urgent of the project Red River delta (RRD) is one of the largest regions of tomato production.Conditions of climate and soil here is favorable to cultivate tomato with many cropseasons around the year, binging good benefits for tomato growers. However,diseases such as bacterial wilt, yellow leaves curly leaf (TYCLV) develop withhigher pressues, resulting in decrease of tomato productivity. Beside that, a large areaof tomato in Red River delta is in main crop season (winter season) with highproductivity but low price, while tomato in off-seasons (summer-autumn, spring-summer) with high product demand but less of area, because weather is not suitablefor good plant growth and lack of suitable tomato varieties. In front of actual demand of tomato production, some research organizations indomestic have introduced some hybrid varieties such as HT7, HT24, Hybird No.9,VT3, FM20, FM29… together with guidelines of intensitive cultivation and initialyapply advance technology innovation of grafting between tomato and egg plant inoff-season production. However, until now, tomato hybrid varieties are with smallsupply of seeds for production due to limited technology of hybid seed production.Moreover, the number of varieties with high productivity and good quality is limitedto meet demands of fresh tomato, tomato for processing and for exportation.Breeding of disease resistance varieties for rootstock becomes an urgent requirementof production, but there are not many studies on rootstock. Materials for rootstock aremaily imported. In addition, technical guidelines are common for all production inoff-season tomato, grafted tomato, which needs to be specified for each variety andeach ecological region. In this context, it is essential to evaluate and rapidly introduce hybrid tomatovarieties imported with high productivity, good quality, good disease resistance, andgood adaptation to crop seasons and intensitive cultivation for Red River delta,providing improvement of crop productivity and economic benefits. Thus, study“Research on identifying new varieties and cultivated techniques protocol toimprove productivity and economic efficiency in tomato production in Red Riverdelta”2. Objective of the project Assess of current status of tomato production in Red River delta in recentyeas, drawing techniques and strategy need to be improved. Evaluate some imported hybid tomato varieties that are suitable for Red Riverdelta with good adaptation, high productivity, good disease resistance in order tocontribute to diversity of tomato varieties. -4- Establish technical guidelines of production for selected varieties. Build a production model of hybid tomato in off-season with large scale insome locals of Red River delta.3. Scientific and Usable contribution of the Project3.1. Scientific contribution Results of study provide some contributions in term of science for tomatoproduction in Red River delta to improve economic efficiency. Provide more scientific evidences, technical solution to improve productivityand economic efficiency of tomato production in Red River delta. Results of study are references for students of crop science major and others whoare interested in research and development of tomato production.3.2. Usable contribution Study draws difficulties and limitations of tomato production, contributingpractically to apply and extend some new techniques fo ...
