Yield trail of some new early rice varieties in defferent ecosystem of Trà Vinh province
Nineteen new rice varieties with short growth duration bred by Cuu Long Delta Rice Research Institute were used as materials for yield trail experiments in salt effected soil area of Da Loc, Chau Thanh and alluvial area with three rice crops per year of Binh Phu, Cang Long, Tra Vinh, in both dry and wet seasons of 2009-2010. These varieties were screened for resistant to Brown Plant Hopper (BPH), Leaf Blast and tolerant to saline condition. At least 2 rice varieties were found with very early maturity, high yield, resistant to BPH, Leaf Blast and suitable for 3 crops per year of Tra Vinh alluvial area, such as OM5451 and OM8923. Three other rice varieties were ditermined with early maturity, high yield, resistant to BPH, Leaf Blast, salt loterance and adaptation with salt effected soil area of Tra Vinh province. They were OM8928, OM6932 and OM5464.
