Introgression of blast resistance genes into the elite rice variety MR263 through marker-assisted backcrossing.
BACKGROUND Blast caused by the fungus Magnaporthe oryzae is a significant disease threat to rice across the world and is especially prevalent in Malaysia. An elite, early-maturing, high-yielding Malaysian rice variety, MR263, is susceptible to blast and was used as the recurrent parent in this study. To improve MR263 disease resistance, the Pongsu Seribu 1 rice variety was used as donor of the ...
متن کاملComparison of phenotypic versus marker-assisted background selection for the SUB1 QTL during backcrossing in rice
Marker assisted backcrossing has been used effectively to transfer the submergence tolerance gene SUB1 into popular rice varieties, but the approach can be costly. The selection strategy comprising foreground marker and phenotypic selection was investigated as an alternative. The non-significant correlation coefficients between ranking of phenotypic selection and ranking of background marker se...
متن کاملMarker-assisted Backcrossing for Identification of Salt Tolerant Rice Lines
SSR or microsatellite markers are proved to be ideal for making genetic maps, assisting selection and studying genetic diversity in germplasm. SSR markers are playing important role to identify gene for salt tolerance that can be helpful for plant breeders to develop new cultivars. The experiment was conducted during the period from July 2009 to November 2010 in the experimental field and Biote...
متن کاملMarker-assisted backcrossing: a useful method for rice improvement
The world's population is increasing very rapidly, reducing the cultivable land of rice, decreasing table water, emerging new diseases and pests, and the climate changes are major issues that must be addressed to researchers to develop sustainable crop varieties with resistance to biotic and abiotic stresses. However, recent scientific discoveries and advances particularly in genetics, genomics...
متن کاملRice Variety Improvement Using Marker-Assisted Selection
Molecular marker-assisted selection (MAS) is currently being employed in two areas of rice breeding at the University of Arkansas Rice Research and Extension Center (RREC) in Stuttgart. Presently the objective of the program is to accelerate the development of rice cultivars with improved cooking quality and rice blast disease resistance using two well-characterized molecular markers. A co-domi...
