[Syrupmakers] This year's new commercial variety - L01-283

[Richard Harrison]

Tracy,
    Nice report. I like the idea of early maturing. I didn't see any mention of lodging resistance, though. Any report on this trait--maybe from other sources?

FYI, anyone interested in getting some of this new variety need to have applications in by Aug. 1, 2008 (orders started July 1).  Cost is $51/ton, picked up in S. La. at specific secondary farmers fields. (I have the list).  The application MUST be on the form in The Sugar Bulletin (I have a copy).  I don’t have enough land ready to plant another ton (~1000 or more linear feet), so I’m thinking about waiting a year to try this one.
 
[Below excerpt taken from the July issue of “The Sugar Bulletin” from the American Sugarcane League.]
 
L01-283 was derived from a cross made in 1996 between L93-365 as the female parent and LCP 85-384 as the male parent.  The stalks are bronze to reddish and are covered with a wax layer.  In the sunlight, the stalks have a more purplish hue.  The new variety has a high population of medium diameter stalks.  Its stalk population is 119% and stalk weight is 91% of LA’s leading variety, HoCP96-540, averaged over plant-cane, first-ratoon, and second-ratoon crops.  L01-283 is an excellent stubbling variety.  Tests indicate a 10% increase in recoverable sugar than 540, is early maturing, and has prouced 4% greater sucrose content (lbs per ton of cane).
 
It is resistant to Sorghum Mosaic Virus, smut, brown rust, and leaf scald.  The affect of yellow leaf disease is unknown at this time.  283 may  sustain significant yield loss in ratoon crops from ratoon stunting disease.
 
To date, seed companies have been unsuccessful in using tissue culture to micropropagate 283 because it exhibits an unacceptably high level of somaclonal variant (off-types).  With limited hot water treatment units in the industry, proper sanitation of harvesting eqt will be important in minimizing the spread of RSD in L02-183.  It is moderately resistant to the sugarcane borer and should be scouted to insure timely insecticide applications.  This variety is a good choice to plant in areas where insecticides cannot be applied.
 
Good luck with planting season!
