A research combine harvests rice on a date-of-planting study at the Rice Research Station near Crowley. The study is conducted with different varieties every year to help determine the optimum planting window.

The medium-grain Clearfield line LA2125, above, and a long-grain Clearfield line, LA2134, are being grown in Puerto Rico this winter for seed increases.

Two Clearfield lines, a long-grain and a medium-grain, are being grown in Puerto Rico this winter for a seed increase and to get more data on grain quality.

“There’s no guarantee that either of these will be released,” said Steve Linscombe, LSU AgCenter rice breeder.

The long-grain line, LA2134, has quality comparable to the variety CL111, Linscombe said, with low chalk and with yields comparable to CL151 and better than CL111.

It has good blast resistance, moderate sheath blight susceptibility and good straight-head resistance.

The medium-grain line, LA2125, yields comparable to CL271 but with a larger grain that is more translucent and better in quality. Linscombe said it has good blast resistance, moderate sheath blight and straight-head resistance.
