The Art And Science Of Plant Breeding, John Sylvester Gladstones

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

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.

1973 Time Of Planting And Rate Of Seeding On Lupin Yield, G Walton

Experimental Summaries - Plant Research

Of the four time of planting trials two definitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 …

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden

Experimental Summaries - Plant Research

A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or "optimum" rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the …

Comments on Results - New Land sites (Graphs 1, 2) - The three sites were very responsive with the point of inflexion about 600 kg/ha super rate (similar to 1972 result). The seed x super rate interaction shows the quicker response to super with higher seeding rates. Low Super Bank (800 kg/ha) (GRAPH 3) - The two sites showed very little response to super applied. On the Eradu sandplain no response to super for either Unicrop or Wheat. On the Watheroo yellow sandplain (73M015) the two lupin cultivers and the wheat gave different responses. High Super Bank (>1 OOOkg/ha) …

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" …

Market Prospects For Rapeseed : 1972-73, R J. Guyton

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

Interest in rapeseed as an alternative crop in the agricultural region of Western Australia was reflected in the area sown in 1971, some 70,000 acres, and an initial export contract of 10,000 tons made in January 1972.

This market report draws upon information released by the Department of Primary Industry and Department of Trade and Industry (both located in Canberra) and research within the Department of Agriculture. Its purpose is to outline future prospects for rapeseed as an aid to decision making for the 1972 season.

Lupin Experiments - Eleven trials were sown during 1973 with the aim of further examining the response of lupins to inoculation on old clover land, new to lupins, and some on new land. The lime pellet and gum slurry methods were compared. The opportunity was also taken to compare a new rhizobia, WU8, with the current commercial inoculant WU425. 1.

Farm Operations Management, H E. Fels, A. W. Hogstrom

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

The main defence of Australian farmers against the cost-price squeeze has been to increase productivity. The tendency is to run more and more stock per man and to grow more crop per man.

Some farmers run unusually large numbers of animal units per man-year.

The operations of 16 such farmers over one year were examined to find out whether it had been profitable for them to reduce labour inputs to such an extent.
