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 crop seasons around the year binging good benefits for tomato growers. However diseases such as bacterial wilt yellow leaves curly leaf TYCLV develop with higher pressues resulting in decrease of tomato productivity. Beside that a large area of tomato in Red River delta is in main crop season winter season with high productivity but low price while tomato in off-seasons summer-autumn springsummer with high product demand but less of area because weather is not suitable for good plant growth and lack of suitable tomato varieties. In front of actual demand of tomato production some research organizations in domestic have introduced some hybrid varieties such as HT7 HT24 Hybird VT3 FM20 FM29. together with guidelines of intensitive cultivation and initialy apply advance technology innovation of grafting between tomato and egg plant in off-season production. However until now tomato hybrid varieties are with small supply of seeds for production due to limited technology of hybid seed production. Moreover .
