| Abstract |
Bacterial blight (BB) has caused significant reductions in yield and
quality of rice. The use of genetically resistant cultivars has proven to
be one of the most effective methods used to address this problem.
This study screened a total of 333 Thai lowland indigenous rice
germplasms against four Xanthomonas oryzae pv. oryzae (Xoo)
isolates under greenhouse conditions in the rainy and dry seasons
of 2017. The ten varieties demonstrating the greatest BB resistance
in the lower five centimeters of the lesion lengths in both experiment
years were further investigated and validated for their agronomic
performances in field conditions at the Udon Thani Rice Research
Center in 2018. Our findings revealed that of the ten BB resistant
lowland rice varieties, five varieties; LLR023, LLR134, LLR137,
LLR205 and LLR207, exhibited high performances of agronomic traits
in field conditions; as found in the plant height, tiller number, panicle
number, panicle length, seeds per panicle, grain yield and harvest
index when compared with the KDML105 check varieties. These five
selected rice varieties may further serve as new genetic resources
for future BB resistance and agronomic trait improvement programs. |
