Lupins In Western Australia. 1. Species And Varieties, John Sylvester Gladstones

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

First in a series of articles on the varieties, cultivation and uses of lupins in Western Australia.

Lupins are ideally suited to the climate and soils of many districts of Western Australia and their cultivation here dates from the early years of the century.

However, although there were some 500,000 acres of lupins growing in the State in 1968, their cultivation in recent years has been largely limited to infertile sandplain soils where other legumes usually fail.

Pasture Seed Production In Western Australia, B J. Quinlivan

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

Pasture seed production in Western Australia is an industry with a somewhat turbulent past. Booms and slumps have been the rule rather than the exception.

However, during the past few years there has been some degree of "stability"—if not in price, at least in terms of total production.

Wheat Diseases In Western Australia, W A. Shipton, W. R. Tweedie, K. J. Locke

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

DISEASES caused by pathogenic organisms can seriously affect the yield of wheat. Some diseases are comparatively rare whereas others occur over a large area of the wheatbelt year after year.

The Certified Strains Of Subterranean Clover : Their Origin, Potential Use And Identification, B J. Quinlivan, C. M. Francis, M. L. Poole

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

SUBTERRANEAN CLOVER originated in the countries surrounding the Mediterranean Sea and in parts of Western Europe.

Therefore it is not surprising that it grows well in the agricultural districts of Western Australia, for these regions have a typically Mediterranean climate with cool wet winters and hot dry summers.

Papaw Varieties For Carnarvon, Michael Gregory Hawson, D. W. Thomas

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

PAPAWS grow very well in the Carnarvon area of Western Australia and throughout the north of the State.

Some produce quite well as far south as Perth.

The History, Characteristics And Potential Of Kondinin Rose Clover, E T. Bailey, N. B. Gayfer

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

Experimental and field performances of rose clover over fen years suggest that it will be increasingly used as a pasture legume in south-western Australia.

A number of lines differing in maturity and leaf markings have been selected locally and given cultivar (variety) names

The first of these lines to be selected was designated Kondinin. This paper describes its origin, history, characteristics and performance.

Stem Rust Of Wheat, H L. Harvey

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

STEM RUST is one of the most serious diseases of wheat and is of world-wide importance.

Fortunately, widespread epidemics are rare in Western Australia because the general climatic conditions are usually unfavourable to the disease.

Nevertheless, localised outbreaks of stem rust are quite common on the Esperance Plains and around Geraldton where seasonal conditions are frequently mild and humid.

The 1963-64 Wheat Stem Rust Epidemic, J T. Reeves

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

Comments on the 1963 epidemic and the current situation regarding rust races and resistant varieties in Western Australia.

THE 1963-64 harvest included 12 million bushels of undergrade wheat, representing 25 per cent, of the total harvest.

The average yield was reduced to only 11.3 bushels per acre. Although these adverse effects were due to a number of causes, the principal one was stem rust.

The economic loss due to this disease in the 1963-64 harvest probably exceeded £10 million.

Recommended Wheat Varieties, 1965 : State Wheat Advisory Committee Recommendations For Wheat Varieties For 1965 Plantings, Department Of Agriculture, Western Australia

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

State Wheat Advisory Committee recommendations for wheat varieties for 1965 plantings.

THE wheat rust epidemic of 1963 has directed attention to resistance of varieties to this disease, new races of which have recently appeared in Western Australia.

However, last year was one of abnormal seasonal conditions, with late summer rains followed by a mild winter, and spring conditions which favoured rust.

Wheat Breeding And Variety Trials, 1963-64, J T. Reeves

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

A review of the wheat breeding and pedigree seed production by the Department of Agriculture.

Yields from the wheat variety trials at agricultural research stations during the 1963-64 season are presented and discussed.

Recommended Wheat Varieties : 1964, Department Of Agriculture, Western Australia

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

THE State Wheat Advisory Committee has issued its official list of recommended wheat varieties for 1964.

Rice Growing In The Ord River Valley, C B. Langfield

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

THE first commercial rice crop in the Ord River Valley was planted late in I960 and plans are in hand for some 35,000 acres of land to be subdivided for irrigation settlement by 1964, with rice as a major crop.

Mosaic Disease Of Cucumbers : A New Resistant Variety, H L. Harvey

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

TESTS with the cucumber variety Ohio MR 200 which was introduced from the U.S.A. (1), have shown it to be almost unaffected by the cucumber mosaic virus. It is a good type and satisfactory yielder and promises to be the answer to the cucumber mosaic problem in Western Australia.

The Fruit Industry In Other Lands. 4. The United States Of America (Continued), Frank Melville

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

COMMERCIAL pear growing was seen only in Washington State where production is in the vicinity of five million bushels or about 12 per cent, of the total fruit production of the State.

Two-thirds of the pears are Bartletts which are used extensively for canning. The other main variety is D'Anjou with lesser quantities of Bosc and Winter Nelis all of which are used for the fresh fruit trade.

In the last six years a serious depletion in tree numbers has occurred due to the inroads of Pear Decline a new disease the cause of which at present is unknown.

Wilt And Cold Resistance Of Self-Fertilized Lines Of Alfalfas, George L. Peltier, H. M. Tysdal

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The relative reactions to cold and wilt of self-fertilized lines of alfalfa through to the fifth generation are reported. Some of the reasons for undertaking a breeding program are given as well as methods used in the controlled cold and wilt determinations. Preliminary studies showed that reinoculating healthy individuals which had already resisted one wilt infection test served to eliminate additional plants, but the percentage healthy was much higher after the reinoculation than after the first inoculation. The foundation materials from which selections were made consisted of selected plants from a number of old Nebraska fields and a large collection …

Winter Wheat Investigations, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Twenty years of wheat breeding, consisting chiefly of the isolation and testing of pure lines, has now been conducted at the Nebraska Agricultural Experiment Station. It is the purpose of this paper to report the conduct and results of this work. The resulting strains are compared with the best other wheats available from Nebraska and other sources. The effects of a number of cultural practices related to the preparation of seed, seeding, treatment of the growing crop, and harvesting are also presented. Some consideration is given to the experimental technique of the comparative tests.

Corn Investigations, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of the investigations reported in this bulletin has been primarily to determine some of the underlying principles involved in corn improvement. The work comprises a study of some of the physiological characteristics of the crop together with a comparison of various selection, breeding, and cultural practices in their relation to grain yield.
