﻿SOME NEW VABIETIES OF RICE. 7 



was distributed in southwestern Louisiana for commercial growing 

 in 1918. Enough seed of Acadia (C. I. No. 1988) was grown in L921 

 to sow at least 40,000 acres in 1922. 



The slender culms of the Acadia variety are light green and 

 usually number 10 to the plant. The average height, including the 

 panicle, is 50 inches. The culm and sheath nodes are dark green. 

 The auricles are deciduous. The ligules average half an inch in 

 length. The leaf blades are narrow, averaging three-eighths of an 

 inch in width. The panicles have an average length of 9 inches, and 

 each bears on an average 132 seeds. 



The seeds (PI. I, H and /) average 7.2 millimeters in length and 

 3.7 millimeters in thickness. The glumes are very pale yellow and 

 have entire margins. The hull loosely incloses the kernel and is 

 of medium thickness and yellow. Its surface has a burlaplike ap- 

 pearance and is thinly covered with white hairs, which are long 

 and conspicuous toward the apex. The apex of the hull terminates 

 in four conical yellow teeth. The two that are prominent are lo- 

 cated on the meson and are of equal length. The other two are 

 lateral, very short, and inconspicuous. 



The kernels (PI. I, J and K) average in length 5.7 millimeters, 

 in width 2.1 millimeters, and in thickness 3.2 millimeters. Viewed 

 laterally, the dorsal and ventral margins are equally convex, and 

 their distal end is broadly obtuse. The opaque area, when present, 

 usually is small and located on the dorsal margin. 



This variety matures in approximately 139 days. It produced an 

 average yield of 2,884 pounds of paddy and 2,020 pounds of straw 

 per acre. It has produced 4,702 pounds of paddy per acre on old 

 rice land in the Mississippi River section of Louisiana and as much 

 as 5,155 pounds on new land in the same locality. On the prairies 

 of southwestern Louisiana yields of 3,800 pounds per acre have 

 been obtained. 



DELITUS. 



The Delitus variety is a pure-line selection from the Bertone 

 variety, which was obtained by the United States Department of 

 Agriculture in 1904 from Vilmorin, Andrieux & Co., Paris, France. 



The selection was made at the Rice Experiment, Station, Crowley, 

 La., by the writers in 1911. The name Delitus is an abbreviation 

 of the Latin word meaning delicate and was chosen also on account 

 of its similarity in sound to the words " delight us." It was applied 

 to this selection in 1917. This selection was increased from nursery 

 to plat experiments in 1914. The plat yields are given in Table 2. 

 The variety was distributed in southwestern Louisiana for commer- 

 cial growing in 1918. The acreage of Delitus (C. I. No. 1206) is 

 small, as at present it is grown only for home use. 



The culms of the Delitus variety are medium in size, brown, slightly 

 flexed at the fourth node, and usually number seven to the plant. 

 Their average height, including the panicles, is 53 inches. The 

 nodes are dark brown and the sheath nodes light green. The inner 

 surface of the lower part of the sheaths and the outer surface of 

 the sheaths near the base are purple. The auricles are not promi- 

 nent, but are persistent. The ligules average five-eighths of an 

 inch in length. The leaf blades are broad, averaging five-eighths 

 of an inch in width. The panicles have an average length of
