7G SEEDS AND PLANTS IMPORTED. 



27201 to 27288— Continued. 



27201 to 27257— Continued. 



27255. Argentine, drown from S. P. T. No. 3507. Source of parent 

 Beed Buenos Aires, Argentina (imported in 1899;. One plant yielded 

 10 grams of seed. 



27256. Utah, irrigated, drown from S. P. I. No. 22558. Source of 

 parent seed, Gunni.-on, Hah (crop of 1907). Eight plants yielded 

 three-fourths pound of seed. Average per plant 42 grams; 530 seeds 

 per gram. 



27257. Argentine. Grown from S. P. I. No. 12549. Source of paroni 

 seed, Buenos Aires, Argentina (imported in 1905). One plant yielded 

 56 grams of seed; 507 seeds per gram. 



"In making comparison as to yield of seed careful notice must be taken of 

 the number of plants from which the yield was obtained. A large number 

 indicates a thicker stand in the rows, hence less opportunity for full develop- 

 ment. Fair comparisons may be made in most cases between strains repre- 

 sented by approximately the same number of plants." 



27258 and 27259. Medicago sativa L. Alfalfa. 



27258. Commercial sand lucern. Grown from potted plants of S. P. I. 

 No. 25110, which were started in the greenhouse at Washington and sent 

 to Dickinson, N. Dak. Original seed received from Zurich, Switzer- 

 land. Fifty-five plants yielded 2f pounds of seed, an average yield 

 per plant of 20 grams. 



Note. — This number and Nos. 27261 and 27262 below were not grown 

 from seed produced at Zurich, but from samples that were submitted by 

 seedsmen of Darmstadt, Germany, to the seed-control station for test. 



27259. Grown from P. L. H. No. 3411, which is inbred Grimm alfalfa 

 produced in 1908 at Dickinson, N. Dak., by a selected plant from the 

 same parent seed as P. L. H. No. 3235 (see No. 27201 above). Present 

 sample grown in 1909. Sixteen plants yielded 1 pound of seed, an 

 average yield per plant of 29 grams. Mr. Waldron reports that the 

 winter of 1909-10 killed a much larger percentage of this inbred strain 

 than the open-pollinated Grimm included in various experiments. 

 Whether this killing was due to deterioration or whether the selected 

 parent happened to be a nonhardy one can not be said, but it suggests 

 an interesting experiment. 



27260. Medicago sativa varia (Mart.) Urb. Sand lucern. 



Grown from P. L. H. No. 3386, which is true sand lucern produced by S. P. I. 

 No. 20571, obtained by Prof. N. E. Hansen from Ultuna, Sweden. Forty- 

 nine plants yielded 2\ pounds of seed, an average per plant of 23 grams. 



27261 to 27266. Medicago sativa L. Alfalfa. 



27261. Commercial sand lucern. Grown at Dickinson, N. Dak., 

 from S. P. I. No. 25111 (see No. 27258 above). Fifty-two plants 

 yielded If pounds of seed, an average per plant- of 12 grams. 



27262. Commercial sand lucern. Grown at Dickinson, N. Dak., 

 from S. P. I. No. 25112 (see No. 27258). Fifty-five plants yielded 

 2\ pounds of seed, an average per plant of 21 grams. 



27263. Seed from volunteer plants that have persisted for several 

 years on the site of an old experimental plat that was possibly Grimm.
