Guinn, Robert Kenneth (Texas A&M University. Libraries, )Purpose The purpose of this study was to determine characteristics of drug use among self-reported Mexican-American drug users. More specifically, it was the purpose of this study to determine the relationship of drug use ...
-
Ali Khan, Syed Tahir (Texas A&M University. Libraries, 1967)A study was conducted to compare and correlate the performance of parents and hybrids in early and late generations of grain sorghum and to evaluate the combining abilities of selections and four male-sterile lines. A cross ...

Mills, Earl Ronald (Texas A&M University. Libraries, 1962)Three marine algal species, Isochrysis galbana Parke (haptophyte), Glenodinium halli Freudenthal and Lee (dinoflagellate) and Cyclotella nana Hustedt (diatom) were exposed to the water-soluble fractions (WSF) and oil-in-water ...
-
Chicco, Giuseppe (Texas A&M University. Libraries, 1970)This study was undertaken to evaluate the genetic variance and the genetic behavior of each of twelve corn composites developed in a reciprocal recurrent selection program. The seed sources used for this study were obtained ...
-
An evaluation of early generation testing for combining ability of restorer lines in grain sorghum Rosenow, Darrell Thaine (Texas A&M University. Libraries, 1970)The effectiveness of early generation testing for combining ability for grain yield in grain sorghum restorer lines was studied at College Station, Texas. Two well-known restorer lines, Tx 7078 and Tx 09, were crossed and ...
-
Bockholt, Anton John (Texas A&M University. Libraries, )During 1963 and 1964 composites from a reciprocal recurrent selection breeding program were evaluated to determine the effectiveness of the program in improving combining ability and maintaining phenotypic variability ...
-
Rosario, Theodore Nieves (Texas A&M University. Libraries, 1970)This study was undertaken to evaluate the discriminating power of gamete selection in the Sq generation and to determine the extent to which combining ability of So genotypes of corn, estimated by the gamete selection ...
-
Alston, Freddy Gene (Texas A&M University. Libraries, 1973)This study was designed to determine if the reciprocal recurrent selection program at the Texas Agricultural Experiment Station at Texas A&M University has improved the probability of selecting a higher frequency of ...
-
Guckert, Larry Gerald (Texas A&M University. Libraries, 1974)Interest in the three-phase relative permeability-saturation relation for porous media has been nearly dormant from the time Leverett and Lewis published their classic work in 1941. The advent of novel recovery methods ...
-
Coy, Anton Ernest (Texas A&M University. Libraries, 1975)A replicated field test was conducted in the Brazos River Valley in 1972 and 1973 to investigate the response of three varied American Upland cotton genotypes to cultural practices thought to be important to the evaluation ...
-
Mouftah, Samir Pacha Mohamed Sabri (Texas A&M University. Libraries, 1968)Mitotic cells from root and leaf tips of seedlings treated with sodium fluoride at the concentration levels of 1x10⁻², 1x10⁻⁴, and 1x10⁻⁶ M were examined. Cytological analyses showed the occurrence of chromosomal gaps and ...
-
Nip, Wai-Kit (Texas A&M University. Libraries, 1969)The location and physical and chemical properties of the pigments in 15 varieties and hybrids of sorghum seeds were investigated. The pigments were found to be located mainly in the stylar area, the epicarp, and the endocarp. ...
