Twelve different trials consisting of 318 treated animals of both sexes and an equal number of controls were conducted in different regions of the state of California. These trails were varied to include animals ranging from an initial weight at the start of treatment of approximately 20 lb. up to approximately 60 lb. In all except one trial, the animals received one 12 mg. pellet or one 15 mg. pellet implanted in the ear. In the exception, an additional group of wether lambs received 3 pellets (36 mg.) of stilbestrol. The results indicate a significant increase in rate of gain due to treatment regardless of age, sex or dietary regime. Animals of younger ages responded as effectively to treatment as older animals. There was no difference in the percent increase in rate of gain of treated animals of either sex, nor did differences in dietary regime affect the response. There was no difference in the rate of gain of wether lambs treated with 12 mg. from those treated with 36 mg. of stilbestrol. |

Agronomic performance and external and internal appearance of watermelon (Citrullus lanatus) fruit are important traits that should be taken into consideration during the development of a new cultivar, as well as being the principal identification elements used by the consumer, which are based on the external appearance and quality of the fruit. Externally, the fruit can be characterized in terms of the shape, the color of the lower rind, and the presence of grooves and stripes, the stripes can be classified as clearly defined or diffuse. The objective of this study was to identify microsatellite markers linked to the stripe pattern of watermelon fruit to support watermelon improvement programs, with the selection of this characteristic in the plantlet stage. F1 and F2 populations, result of a cross between the cultivars BRS Opara (clearly defined stripes) and Pérola (diffuse stripes), were phenotyped for their fruit stripe pattern. The CTAB 2X protocol was used for DNA extraction and 116 microsatellite markers were examined in a group of F2 plants that had fruit with well-defined stripes and fruit with diffuse stripes. The microsatellite loci MCPI_05 and MCPI_16 exhibited a linkage to the stripe pattern at a distance of 1.5 and 1.8 cM, respectively, with LOD scores of 39.28 and 38.11, respectively, which were located on chromosome six of the watermelon genome. These markers can be used in marker-assisted selection in watermelon improvement programs, by various research institutions.
