The selected plants were propagated clonally in the greenhouse dur- 

 ing the ^^■inter. Cuttings of plants 1 to 9 were set in triplicate for caging. 

 As the season developed, bees were introduced into the cage and seed was 

 secured from each plant. This seed now awaits propagation and the 

 progen}' will be subjected to further testing. 



All 24 plants were used for testing in small plots. Clonal material 

 from each was set in triplicate plots, 3 x 6 feet. 14 cuttings per plot, on 

 land that had been seeded currently to orchard grass. Competition, height, 

 ability to recover after clipping, and similar factors are being noted. 



A few of the 15 plants in this group, not caged in 1944, appear to 

 have more promise than many of the nine that were caged; hence, the 

 cage will again be used in 1945. with a new grouping for seed production 

 of the most desirable material. 



Plant materials from other stations are being subjected to similar field 

 tests. 



Red Clover. Twent\'-five potted seedlings were brought into the 

 greenhouse for the usual winter crossing. These seedlings represent the 

 more persistent of the 12 families selected for their ability to live more 

 than t\\o seasons; Fl, F2 and F3 generations are obtained by intercross- 

 ing. 



This year, none of the old plants of the 12 original families were 

 alive in the field plots. Some of the original plants had produced seed as 

 many as four or five seasons. Seed multiplication has continued both in 

 the field and in the plot areas. In spite of excess winter kiUing of all 

 plants, there are a few plants that now are three years old. 



From now on an attempt will be made to discard plants that show 

 disease and general lack of vigor, and to test bulk seed of this new strain 

 along ^^'ith other standard and improved strains. After this selection and 

 testing, an effort will be made to multiply the strain rapidly if it shows 

 sufficient promise. 



T'wiothy (Pleinii Pratense). Due to unfavorable soil conditions on 

 the area in which seed from clonally propagated plants were seeded, it 

 was impossible to check the behavior of individuals in the two strains of 

 timothy under observation. In the spring of 1945, seed from each clone 

 will again be planted for testing. 



Plantings of composites of each strain have been made for seed in- 

 crease. About 50 pounds of the late hay and five pounds of seed of the 

 pasture strain ^\'ere secured in 1944. This seed will be tested in 1945, 

 probably in some trials on farms.

Producing the Full Roughage Requirements on New Hampshire 

 Dairy Farms with Special Reference to Pastures 



This study is carried out on eight pastures, seven of which \\ere 

 seeded in 1942 and one in 1943. Seed mixtures included Ladino in all 

 cases, supplemented with strips or plots of one or more of the large 

 grasses, namely, timothy, orchard grass, smooth brome grass, reed canary 

 grass, tall fescue and perennial rye grass. A study of seeding rates is in- 

 cluded on two farms.
