Rice tungro disease was discovered in Malaysia in the 1930s. The first and only genome of Rice tungro bacilliform virus (RTBV) isolated from rice in Malaysia was sequenced in 1999. After nearly two decades, here, we present the complete genome sequence of an RTBV isolate in rice from Seberang Perai, Malaysia.

Five new rice lines, namely, P589, P590, P591, P592 and P593 and three control varieties, MR253, MR263 and MR84 were evaluated in a preliminary yield trial for yield, yield components, physico-chemical properties as well as resistance to pests and diseases. Most of the new rice lines showed early maturation (102-120 days) and culm height ranged fro...

Pesticides are widely used in paddy field to control pests, diseases, weeds and other rice pathogens in minimizing a serious loss in rice production. The presence of pesticide residues and metabolites in rice, water, soil, currently represents a major environmental pollutant issues. It sometime will cause insect pest outbreaks in paddy field. An el...

CMS (cytoplasmic male sterile) line is one of the most important hybrid parents in hybrid rice production technology using Three-Line systems. Test-crosses for selection of candidate local maintainer lines were conducted using 24 rice varieties and two CMS-WA (wild abortive) lines IR78374A/B and 1A/B. The F1of the two combinations, namely IR78374A/...
