Flooding is one of the major hazards of rice production for the rainfed lowland rice ecosystem, and tolerant cultivars are urgently needed to help protect farmers from submergence damage. A quick and efficient strategy was implemented to introgress SUB1, a major QTL for submergence tolerance, into a rainfed lowland mega variety BR11 of Bangladesh by only(More)
Marker assisted backcrossing has been used effectively to transfer the submergence tolerance gene SUB1 into popular rice varieties, but the approach can be costly. The selection strategy comprising foreground marker and phenotypic selection was investigated as an alternative. The non-significant correlation coefficients between ranking of phenotypic(More)
A total of 300 germplasm accessions collected from submergence-prone areas of Bangladesh were selected from the genebank of the Bangladesh Rice Research Institute (BRRI) for an allelic diversity study on submergence tolerance during the vegetative stage. Through screening under controlled submergence for three consecutive years, eight accessions were(More)
Hybrid rice varieties have higher yield potential over inbred varieties. This improvement is not always translated to the grain yield and its physiological causes are still unclear. In order to clarify it, two field experiments were conducted including two popular indica hybrids (BRRI hybrid dhan2 and Heera2) and one elite inbred (BRRI dhan45) rice(More)
Arsenic phyto-toxicity is a limiting factor affecting rice production in the Indo-Gangetic flood plain. In this study, 98 microsatellite markers were used to map quantitative trait loci (QTL) conferring arsenic phyto-toxicity tolerance (AsT) at seedling stage from a F2 population derived from a cross between an arsenic sensitive indica rice cultivar (BRRI(More)
An experiment was carried out to study the genetic components for eight panicle characters in rice using an 8-parent half diallel cross excluding reciprocals during Transplant Aman season, 2003. The parental genotypes used in the study were BRRI dhan29, BR4828-54-4-l-4-9, BRR1 dhan28, 1R8, Amol3, 1R6561038-2-4-2-6-3, Minikit and ZhongYu7, which were chosen(More)
