Inheritance of resistance to bacterial blight and implication for rice improvement in Uganda
Abstract
99 words
Bacterial blight caused by Xanthomonas oryzae pv.oryzae, is
a destructive disease of rice worldwide. Resistant varieties are
the best option to avert the disease. Thirty resistance genes
identified face a wide genetic diversity exhibited by the
pathogen. Information on local isolates is not available and
genetic mechanism for resistance harbored in Ugandan
germplasm is unknown. Experimental sites were Makerere
University and NaCRRI. Differential cultivars from Africa Rice
were used to group Ugandan isolates. Seven parents were
crossed into a half diallel to produce F1 and F2 progenies for
determining the inheritance of resistance through inoculation.
Preliminary results are reported.
