Rehabilitation of Huyet Rong rice variety in Vinh Hung District, Long An Province

Abstract

Rehabilitation of the special rice variety “Huyet Rong” was implemented under the cooperation between Department of Science and Technology of Long An province and Mekong Delta Development Research Institute from 2012 to 2014 using the protein electrophoresis SDS-PAGE to choose seeds that have a low amylose content based on the colouring levels in the waxy page and some other techniques to shorten the selection process. From the results of field and laboratory selections, the Huyet Rong variety has been successfully rehabilitated with the typical traits such as plant height of 110-125 cm, weight of 1000 grains in the range of 24-26 g, long grain, low amylose content ranging from 14 to 15.5%, protein content of 7.5- 8.5%, yield potential of 3.5 tons/ha, and resistance to blast disease. The suitable cultivating schedule for the Huyet Rong variety should be from August 15 to September 15, and harvesting in December. The rehabilitated Huyet Rong variety will create a special product of rice for Long An province.
