Abstract One of the biotic constraints in rice production worldwide is blast disease which can control by planting resistant varieties. To find out effective resistance, resistance quantitative trait loci (QTL) were mapped against 20 and 3 virulent isolates for leaf neck blast, respectively, using 111 doubled haploid lines from cross IR64 Azucena. QTLs associated with found on chromosomes 1, 2,...

The increased occurrence and severity of drought stress have led to a high yield decline in rice in recent years in drought-affected areas. Drought research at the International Rice Research Institute (IRRI) over the past decade has concentrated on direct selection for grain yield under drought. This approach has led to the successful development and release of 17 high-yielding drought-toleran...

To support increased rice production, the government is trying to increase use of superior varieties in farming. In line with this, a study has been carried out aimed at analyzing developments, problems distribution, and farming improved varieties. The research was conducted Central Java Province 2020. sample consisted 30 farmers various institutions related this study. Data analysis quantitati...

Drought is one of the major constraints rice production in Indonesia. Climate change increases risk drought incidences. The evaluation resisting genotypes available Indonesia would hopefully find and enhance such resistance which could be utilized to further tested releasing a variety or donor parent within drought-resistant breeding program. Raised bed system (RBS) relatively reliable method s...
