More than 50% of Thailand’s rice production area (about 6.4 Mha in 2014) belongs to its Northeastern region, which is Thailand’s largest area of rain-fed rice production .
The purpose of this study was to breed SKN for blast resistance, using marker-assisted backcrossing, together with phenotypic selection.
More than 0.8 Mha of Northeast Thailand has the capacity to grow upland rice.
The climate is drier than other regions, yet proves suitable for growth, as upland rice needs less water to grow .
The causal pathogen of blast, known as Controlling blast through cultural practice remains difficult due to numerous environmental factors which contribute to the epidemic.
Blast spreads quickly during the rainy season, which is characterized with high humidity and a high rate of nitrogen fertilizer application, which further aids disease development .
The breeding population was constructed by crossing the SKN (recurrent) with the RD6 introgression line (donor), which contained four blast resistant quantitative trait loci (QTLs).
