This book was released on 1978 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study was to determine if the three cycles of recurrent selection for first-brood corn borer resistance also caused, or was accompanied by, significant changes in several important plant, ear, and grain traits. For a trait such a first-brood corn borer resistance, which is highly heritable when artificial infestation is used, favorable changes can be effected easily by the recurrent selection breeding procedure. Consequently, in certain circumstances it may be desirable to make such an improvement in a synthetic (or more than one highly heritable trait could be improved) before the synthetic is used for other purpose such as a source for new inbred lines. Therefore, it is important to know if unfavorable changes for other important traits may occur as correlated responses while the recurrent slection for the highly heritable trait is in progress. Although statistical significance may be obtained rather easily in experiments that have a high level of precision (relatively low experimental error and a high number of degrees of freedom), the breeder must decide if the differences observed are reat enough to be of practical importance. In the present study, significant variation was expected for population types and synthetics. The items of most interest were the main effects of corn borer treatment and cycles and interactions involving one or the other of these main effects. It was unfortunate that higher levels of corn borer infestation were not obtained in the (...).

Book excerpt: Excerpt from European Corn Borer Investigations: Experiments With Insecticides on Early Sweet Corn This is a progress report of investigations that are not complete in all phases. The preparations employed were largely experimental, designed for use against the European corn borer, and had not been used previously in field experiments. Several of the preparations obviously lack physical properties that are highly desirable in corn borer insecticides, but some of these materials may Show considerable improvement with further develop mental research. This is particularly true Oi some of the preparations Of fixed nicotine. Preparations of derris, phenothiazine, and nicotine tannate in spray form and a dual-fixed nicotine dust provide sufficient reduction in borer populations to warrant their use in field tests to ascertain their value under commercial conditions and practice. Severe tests of weathering capacity and wash-resistance were imposed upon the materials used in these experiments. During the field experiments conducted in 1935, residues were subjected to frequent rains or light showers, and in 1936 they were again affected by the frequency and also the beavi ness of the rainfall.
