(Texas A&M University. Libraries, 1987)The objectives were broad in scope, but they centered around the theme of disease resistance. In Chapter 2, the techniques used in evaluating the general resistance (pustule density and AUDPC) were shown to be efficient. ...

(Texas A&M University. Libraries, 1985)Field, greenhouse and laboratory studies were conducted to determine the effect of cotton trichome density on parasitism and predation of Heliothis zea (Boddie) eggs. In a no-choice field test of three cotton phenotypes ...
-
(Texas A&M University. Libraries, 1987)Twenty-three peanut genotypes (Arachis hypogaea L.) were evaluated for kernel resistance to Aspergillus parasiticus infection under high relative humidity. The lowest degree of infection, less than 30% was noted in kernels ...

(Texas A&M University. Libraries, 1988)A procedure for detecting cucumber fruit resistance to belly rot induced by Rhizoctonia solani is described. Inoculum in an unsterilized soil, naturally infested with Rhizoctonia solani Kuehn, AG-4, was increased by placing ...
-
(Texas A&M University. Libraries, 1991)Sorghum (Sorghum bicolor L. Moench) cultivars were mechanically inoculated with sorghum yellow banding virus (SYBV) to determine their reaction to the virus. Of the 378 cultivars tested, 129 were susceptible and 249 were ...
