Cache RiverValley Seed will offer the following

rice varieties: 



A high yielding, semi-dwarf medium grain variety developed by LSU.  Jupiter has a good disease package, displaying good resistance to blast, panicle blight, sheath blight, and straighthead.  It has shown good seedling vigor and milling quality.  The grain size of Jupiter is somewhat smaller than Bengal.

Titan is a high yielding, very early maturing, and short stature medium-grain rice developed at the University of Arkansas Rice Research and Extension Center in Stuttgart, Arkansas.  Titan has outstanding yield potential, good milling and grain quality, and improved lodging and blast resistance compared with the current commercial medium-grain cultivar Jupiter.  The flag leaf of Titan is longer than that of Jupiter and well above the panicle canopy at maturity.  The leaves, lemma, and palea are glabrous.  The spikelet is straw colored.  The apiculus is red or purple at heading and the color fades as grains approach maturity.  The grain is non-aromatic.

Taurus is a high-yielding, very early maturing, and short stature medium-grain rice cultivar released by the University of Arkansas System Division of Agriculture in 2023. It was originally selected from the cross ‘Rico 1’/‘Bengal’//‘RU0602162’/‘RU0502031’. In addition to the good milling and grain quality, Taurus has a semi-dwarf plant type, averaging 36 inches in height, and is moderately susceptible to lodging. Taurus matures 3 days earlier than Jupiter and 3 later than Titan. The maturity of Taurus has averaged 86 days from emergence to 50% heading. Taurus was rated is moderately susceptible to leaf blast, susceptible to sheath blight, and bacterial panicle blight.



Diamond rice is a very high yielding, very short-season, long-grain rice developed at the Division of Agriculture’s Rice Research and Extension Center in Stuttgart, Arkansas. Diamond is close in maturity to LaKast and about 4 to 5 days earlier than the Roy J varietal.  Diamond has straw strength of 3 (equal to Wells) compared to a 4 for LaKast and 1 for Roy J. Diamond is 104 cm in plant height which is similar to Roy J and Wells. Rough rice grain yields of Diamond have consistently ranked as one of the highest in the Arkansas Rice Performance Trials.

Ozark is a high-yielding, early maturing, and traditional stature long-grain rice cultivar released by the University of Arkansas System Division of Agriculture in 2022. The line’s pedigree is ‘Diamond’/‘LaKast’. Ozark has an outstanding grain yield, good milling yields, and grain quality. The average plant height of Ozark is 44 inches and the variety is moderately susceptible to lodging. The maturity of Ozark has averaged 88 days from emergence to 50% heading. Ozark was rated susceptible to leaf blast, neck blast, sheath blight, and bacterial panicle blight.

Jewel (RU1701087) rice is a high yielding, mid-season, long-grain rice cultivar developed at the Rice Research and Extension Center (RREC), University of Arkansas Division of Agriculture in Stuttgart, Arkansas. This cultivar was approved for release following the 2019 growing season.  Jewel is about 3 to 4 days earlier than 'Roy J' in maturity.  Jewel has straw strength similar to Diamond which is an indicator of lodging resistance.  Jewel has a canopy height of 37 inches which is comparable to Diamond and LaKast with canopy heights of 36 inches. 



Rice Seed Production Rice seed is planted by only the top seed growers in our area.  Production fields are monitored throughout the growing season by our Agronomist and Seed Certification Manager for off-types, red rice, and  other noxious weeds.  As a general rule, all certified seed is rogued 3 times and all registered seed fields are rogued 4 times.

CRVS Conditioning Process    Step 1:  The seed is conditioned using a Cimbria Delta 108 Seed Cleaner.Step 2:  After the cleaner, the seed is then processed over and LMC Gravity Table. Step 3:  Our rice seed is then run through Carter Disc Machines to remove cracked seed. Step 4:  Long grain rice is then run through a precision grader to insure against medium grain, off-types and red rice. 

Seed Treatments  Cache River Valley Seed offers funigicide seed treatments such as Dynasty, Apron and Maxim to protect the yield potential of the seed after it is planted.  Giberellic acid (Release) and zinc seed treatments are also offered.     

Packaging  Cleaned rice seed is packaged in 50 lb. paper bags, 2025 lb. (45 bushel) bulk bags, and stored in bulk bins.  Sorting rice in bulk bags allows us to keep more cleaned seed on hand for faster load out time.   

Final Certification The Arkansas State Plant Board pulls a 4 pound sample from each lot and checks for germination and purity.  NO RED RICE can be found in this sample in order for it to make Arkansas Certified quality.  

Did You Know?   If your rice seed contains 1 red rice in a 4 pound sample,  planted at a rate of 3 bushels per acre, you would plant over 33 grains of red rice per acre.  Each grain could produce 12 tillers per plant @ 150 per head for a total of approximately 59,400 seeds per acre in the first year and over two million per acre in the second year.  The Arkansas State Plant Board has found that less than 1% of all cleaned certified rice samples contain barnyard grass but that 50% of all rough samples are found to contain barnyard grass.   
Arkansas requires a 4 pound sample for each lot of cleaned seed.  The state of Mississippi only requires a 1 pound sample for testing.  This means that Arkansas has 4 times as much rice which could be milled and checked for red rice and off-types.  All seed rice for sale, both rough and cleaned seed,  must have a complete analysis that includes a purity and germination.
