Results Of Systematic Analyses For Protein And Lysine Composition Of Common Wheats (Triticum Aestivum L.) In The Usda World Collection, K. P. Vogel, V. A. Johnson, P. J. Mattern

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Protein and lysine contents of 12,613 common wheats of the USDA World Wheat Collection were determined in order to identify wheats that may be sources of genes for high protein and high lysine. Results indicate that significant genetic differences in protein and lysine content probably exist among world collection common wheats. Selection criteria have been developed for further evaluation of World Collection lines high in protein and lysine content.

Wheat Quality In W.A, J A. Parish

Journal of the Department of Agriculture, Western Australia, Series 4

Three separate quality classes or categories of wheat are now received by C.B.H. These are a soft biscuit wheat, a hard bread wheat and a mixed grain suitable as a filler wheat in bread-making and for making noodles.

In this article the basis of quality differences between these classes of wheat is described and some of the terms and concepts used in distinguishing between cultivars (varieties) and classes of wheat are discussed.

The first part of this article described the evolution of crop varieties and their improvement by simple selection. This part discusses cross-breeding and the other techniques which underly most modern plant breeding programmes.

The purpose cf crossing is to generate new combinations of varietal characteristics. It does not create anything basically new. All the genetic "ingredients" of a new variety must be present in one or other of the parents.

The Art And Science Of Plant Breeding, John Sylvester Gladstones

Journal of the Department of Agriculture, Western Australia, Series 4

Whether he has known it or not, man has influenced the evolution of plants throughout his whole existence. In the pre-agricultural state he collected fruits and seeds from plants chosen for their useful or desirable qualities, and dispersed them wherever he went. With the neolithic revolution and the development of agriculture, some of these plants were taken into cultivation.

Consciously or unconsciously he selected types with higher yield, which germinated readily when planted, and whose seeds stayed in the head at maturity rather than being shed as in the wild grasses and legumes. Over thousands of years this "guided evolution" …
