Mapping of quantitative trait loci associated with resistance to brown planthopper in background of Swarna from a traditional variety PTB33

Among all the insect pests, brown planthopper (BPH), Nilaparvata lugens (Stal) (Homoptera: Delphacidae) is one of the most destructive pests of rice causing severe yield losses. In this study, an attempt was made to map QTL associated with resistance to BPH using a RIL (F7) population derived from the cross Swarna/PTB33 using standard seedling seedbox screening technique (SSST) at seedling stage, modified mass tiller screening (MMTS) at...
