SALT TOLERANCE RICE GENOTYPES FIELD TRIP AT BA TRI, MEKONG DELTA
ANNOUNCEMENT by HATRI; 09 FEB 2020
On February 7th 2020, field trip workshop was conducted at My Nhon Seed Station, Ba Tri District, Ben Tre Province due to the cooperation with the High Agricultural Technology Research Institute (HATRI). The contributors included 82 farmers and agri-staffs from Ben Tre others in Mekong saline intrusion areas. The workshop aims at assessing and selecting best rice genotypes for 2020 summer to meet the demand of salt tolerance and high quality. The workshop introduced new rice genotypes under salt stress of Ba Tri with 2-3 ppt at flowering stage. The Ben Tre High-tec Agricultural Centre included Mr. Vo Hoai Chan chaired the workshop.

Thanks are due to Mr. Nguyen Thanh Nhan – Head of the research station, attempting to demonstrate experiments for two years and explaining the fluctuation of salt stress during the season to farmers. “The rice genotypes express their salt tolerance as HATRI 200, HATRI 174, HATRI 194 (expanded to roughly 1 ha) under field salt stress of 3 ppt.
“The effects by climate change are hitting the poorest and most vulnerable hardest. We need to lessen the impact and make sure those who depend on small-scale farming are more resilient in order to secure their livelihoods. With 19 new varieties at field salt stress of 2- 3 ppt, we selected good lines well adapted to Ba Tri, Ben Tre.” Prof. Lang said.
Climate change is not just a problem for the future. It is happening now. It is already affecting the food security and incomes of small-scale farmers. I would like to thank HATRI and Ben Tre province for this additional contribution which demonstrates some lines salinity rice varieties as a driver of poverty and hunger. This new salinity varieties helps ensure that farmers can adapt at Mekong delta.
This is a research subject to salt-proof for the Mekong DELTA funded by the HATRI Institute, now the topic has chosen to breeding program and multiply 19 promising rice genotypes to select the 2-3 elites suitable to Ben Tre first then others. Many thanks to local supporters for doing good experiments for this project.
Thanh Phu Agricultural Officer - Mr Tai said "All breeding lines exhibited obviously: some dead, some develop better like HATRI 2000 to be the most promising, which could be developed in Thanh Phu in the future.”

Mr Nghia in Long An said “Farmers in the province prefer HATRI 200, HATRI 174 and HATRI 170. They are are highly productive in terms of production under problem soils with high yield.”
Mr Viet in Tra Vinh also recorded these rice lines that are good under saline area to develop next time in Tra Vinh province.
Prof. Bui Chi Buu answered questions from farmers and agri-staffs for salt tolerance rice genotypes and rice markets in the world today.

In discussions the representatives of local officials and farmers participating in the selection and recognition results with the highest number of votes are the varieties following table 1.

Finally, Director of Ben Tre High-Tec Agri Centre concluded that "We are grateful to Prof. Nguyen Thi Lang cooperatin and Prof. Bui Chi Buu visiting to help Ben Tre develop new rice genotypes adapted to climate change impacts. Hopefully the cooperation would be fruitful.”
