Straighthead or is a physiological disorder in rice resulting in distortion and missing grains on the panicle. It has been estimated that straighthead costs the rice industry over $1 million per year. Crop losses range from 10 – 30% in medium grain and as high as 90% in short and long grain rice. Straighthead occurs in almost all rice growing areas in NSW on a range of soil types.
This RIRDC project contributed to the development of a technique to evaluate new rice genotypes for straighthead tolerance under glasshouse conditions. This will substantially benefit the rice breeding program in pursuing high yielding rice varieties tolerant to straighthead.
