Book excerpt: Excerpt from Results of 1968 Regional Cotton Variety Tests by Cooperating Agricultural Experiment Stations: Alabama, Arizona, Arkansas, California, Georgia, Louisiana, Mississippi, Missouri, Nevada, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas The regional cotton variety testing program was developed from recommendations of the Joint Cotton Breeding Policy Committee and plans of the National Cotton Variety Testing Committee. The members of these two committees as of January 1969 are given on page 103, Data for the 1968 regional cotton variety tests were drawn from selected locations involved in the variety testing programs of 15 State agricultural experiment stations. For this reason, details of design, plot size, cultural practices, number of entries, and sampling methods were left to the discretion of the participating stations. While these details were not rigidly standardized, all tests were conducted by experienced personnel using sound experimental designs and procedures. The operations and measurements required for the development of data on yield and such other agronomic characters as boll size and lint percentage were performed by personnel at the cooperating stations. Fiber samples were sent to the u.s. Cotton Fiber and Spinning Laboratories, Knoxville, Tenn., where fiber and spinning tests were made. All data were assembled in the Cotton and Cordage Fibers Research Branch, Crops Research Division, Agricultural Research Service, u.s. Department of Agriculture, Beltsville, Md. Analysis of the data was directed by the Biometrical Services Staff of ars. The computations were performed by the Data Systems Application Division. The number of replications for yield data ranged from two to eight, but a great majority of tests had six replications from each variety at all stations. Boll, seed, fiber, and spinning data were based on two replications from each variety at all stations. A randomized block analysis was employed, although some tests were planted in lattice designs. Separation of means was by Duncan's multiple range method at the level of probability. Results for the first 3-year cycle of testing were reported in u.s. Agricultural Research Service publications ars 34-30, ars 34-43, and ars 34-60 for 1960, 1961, and 1962, respectively. Results of the second 3-year cycle of testing were reported in ars 34-68, ars 34-81, and ars 34-82 for the years 1963, 1964, and 1965, respectively. Results of the first 2 years of the third 3-year cycle were reported in ars 34-96 and ars 34-105 for 1966 and 1967, respectively. This bulletin reports the last year of the third 3-year cycle (1968 season). About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
