INTRODUCTION
1. 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, spring-
summer) 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 No.9,
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, the number of varieties with high productivity and good quality is limited
to meet demands of fresh tomato, tomato for processing and for exportation.
Breeding of disease resistance varieties for rootstock becomes an urgent requirement
of production, but there are not many studies on rootstock. Materials for rootstock are
maily imported. In addition, technical guidelines are common for all production in
off-season tomato, grafted tomato, which needs to be specified for each variety and
each ecological region.
In this context, it is essential to evaluate and rapidly introduce hybrid tomato
varieties imported with high productivity, good quality, good disease resistance, and
good 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 to
improve productivity and economic efficiency in tomato production in Red River
delta”
2. Objective of the project
Assess of current status of tomato production in Red River delta in recent
yeas, drawing techniques and strategy need to be improved.
Evaluate some imported hybid tomato varieties that are suitable for Red River
delta with good adaptation, high productivity, good disease resistance in order to
contribute to diversity of tomato varieties.

Establish technical guidelines of production for selected varieties.
Build a production model of hybid tomato in off-season with large scale in
some locals of Red River delta.
3. Scientific and Usable contribution of the Project
3.1. Scientific contribution
Results of study provide some contributions in term of science for tomato
production in Red River delta to improve economic efficiency.
Provide more scientific evidences, technical solution to improve productivity
and economic efficiency of tomato production in Red River delta.
Results of study are references for students of crop science major and others who
are interested in research and development of tomato production.
3.2. Usable contribution
Study draws difficulties and limitations of tomato production, contributing
practically to apply and extend some new techniques for tomato production in Red
River delta.
Results of selection and evaluation of new hybrid tomato varieties
accompanied by appropriate cultivation techniques and introduce 02 varieties of
rootstock (variety Hawaii 7996 and cà gai), contributing to diversity of tomato
varieties and improving crop productivity and quality of commercial hybrid tomato
and promote development scale of tomato production with higher economic
efficiency in Red River delta.
4. News results from Project
Evaluate status of tomato production in Red River in period 2008 – 2011,
resulting in some direction of research to overcome difficulties to improve production
efficiency of growers.
Select, evaluate and introduce 03 potential tomato varieties: TAT072672, Savior
and TAT062659 with high productivity, good disesase resistance, suitable for
production in main crop season as well as in off-season in Red River delta. In 2012,
production area of 2 varieties Savior and TAT072672 is up to 1382.4 ha and 328.3
ha. Variety TAT062659 was introduced into production in 2013.
Establish cultivated tecniques for improving of productivity for 2 varieties
TAT072672 and TAT062659 in different crop season in Red River delta.
Evaluate and introduce 02 new varieties of rootstock suitable for variety Savior:
Hawaii 7996 and cà gai. Establish farming guidelines for cultivation of grafted
tomato in different crop seasons in Red River delta. Productivity of Savior grafted
tomato from demotrations is higher than tomato of the check, resulting in 18.7 –
34.1% bebefit increaments.

Introduce some protential hybrid tomato varieties in some province: Hai Duong,
Hung Yen, Vinh Phuc, Hanoi… which are widely accepted by tomato growers. In
2012, production area of 2 varieties Savior and TAT072672 is up to 1382.4 ha and
328.3 ha. Variety TAT062659 was introduced into production in 2013.
