Mapping of a Major Resistance Gene to the Brown Planthopper in the Rice Cultivar Rathu Heenati
A Sri Lankan indica rice (Oryza sativa L.) cultivar Rathu Heenati was found to be resistant to all the four biotypes of the brown planthopper (BPH) (Nilaparvata lugens Stål). In the present study, we constructed a linkage map to identify the locus (loci) for the BPH resistance genes, using an F2 population from a cross between Rathu Heenati and a susceptible cultivar 02428. Insect resistance wa...
متن کاملEffects of Slag-Based Silicon Fertilizer on Rice Growth and Brown-Spot Resistance
It is well documented that slag-based silicon fertilizers have beneficial effects on the growth and disease resistance of rice. However, their effects vary greatly with sources of slag and are closely related to availability of silicon (Si) in these materials. To date, few researches have been done to compare the differences in plant performance and disease resistance between different slag-bas...
متن کاملIdentification of quantitative trait loci associated with resistance to brown planthopper in the indica rice cultivar Col.5 Thailand.
The brown planthopper (BPH) is one of the most serious insect pests of rice throughout Asia. In this study, we constructed a linkage map to determine the locus for BPH resistance gene, using an F(2) population from a cross between a resistant indica cultivar, 'Col.5 Thailand', and a susceptible cultivar '02428'. Insect resistance was evaluated using 147 F(3) families and the genotype of each F(...
متن کاملIdentification of a new locus conferring antixenosis to the brown planthopper in rice cultivar Swarnalata (Oryza sativa L.).
The brown planthopper [Nilaparvata lugens (Stål); BPH] has caused severe damage to rice production. The identification of resistance genes and the development of BPH-resistant varieties are economical and effective ways to manage this pest. Using an F2 population from a cross between the Indica cultivars 93-11 and Swarnalata, we mapped the Qbph-8 locus to a 7.3-cM region on chromosome 8 in two ...
متن کاملBreeding of new rice cultivar ‘Tohoku 194’ with ‘Sasanishiki’-type good eating quality of cooked rice
Cooked rice of 'Sasanishiki' is soft and not as sticky as those of Japanese leading cultivars 'Koshihikari' and 'Hitomebore'. As a method for efficient selection of a breeding line having a good eating quality like that of 'Sasanishiki', the use of physical properties of cooked rice and cooking quality was examined. There were differences of physical properties of the surface layer, starch-iodi...
