Varietal differences among ten rice cultivars showed that stem diameter is a key factor in lodging resistance (measured in terms of pushing resistance). Two near-isogenic lines (NILs) were selected… (More)

A gene underlying a quantitative trait locus (QTL) controlling plant height on chromosome 1 (QTLph1) in rice (Oryza sativa L.) was identified using the candidate-gene strategy. First, the function of… (More)

Carbohydrate contents varied with position in a leaf sheath, and differed between the flag leaf sheath and the second leaf sheath below the flag leaf (-2 leaf sheath) in rice (Oryza sativa L.). In… (More)

A new locus responsible for increased yield potential across the genetic background in rice (Oryza sativa L.) was identified and evaluated. Quantitative trait loci (QTLs) were analysed for the ratio… (More)
AbstractHere, we propose new improvement targets capable of decreasing loss of the sturdiness of the lower part in the rice plant (Oryza sativa L.), thereby improving lodging resistance. In nine rice… (More)

We investigated the reason for carbohydrate retention in the stem of rice (Oryza sativa L.) at full-ripe stage in a near-isogenic line (NIL63) carrying prl5, which confers lodging resistance without… (More)
