Appraisal For Combined Pea Aphid And Spotted Alfalfa Aphid Resistance In Alfalfa, W. L. Howe, W. R. Kehr, C. O. Calkins

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Sources of combined resistance to spotted alfalfa and pea aphids were found in Ranger alfalfa and its parental strains, foreign plant introductions, clones and their progenies. Ranger alfalfa appeared to be a good source for selection of plants with resistance to both aphids.

Cytoplasmic Male Sterility And Intergrafts Between Lycopersicon Esculentum And Solanum Pennellii Corr., W. R. Andersen

Journal of the Minnesota Academy of Science

Attempts to transmit cytoplasmic male sterility through intergrafts between Lycopersicon esculenfum and Solanum pennellii have been unsuccessful. This implies that in these materials, the factor conditioning cytoplasmic male sterility is noninfective. The results of this study and other similar studies by other workers suggest the possibility that grafting might be used as a tool in the classification of cytoplasmic factors affecting mole sterility in plants.

Maintaining The Quality Of Western Australia's Oat Harvest, J L. Mcmullan, J. A. Parish, C. V. Honner

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

WESTERN AUSTRALIA deservedly enjoys the reputation of being a producer of oats of high milling quality.

Because of this, we have been able to develop valuable export markets which pay a premium for our oats.

For some time Ballidu has been rated as the best milling oat in W.A.

The work reported in this article indicates that other recommended varieties are equal to or better than Ballidu for milling.

THE varieties Prior and Beecher are recommended for 1966 by the Coarse Grains Advisory Committee and the Department of Agriculture.

The areas suitable for these varieties when planted for various purposes, are given in the map and table.

Oat Variety Trials, 1964, J L. Mcmullan, J. A. Parish

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

AVON and the new fixed crossbred from N.S.W., * P8304, were the highest yielding oats in the last season's trials.

These are of midseason maturity. The highest yielding oats of early maturity were Irwin and Kent.

Barley Variety Trials, 1964, J L. Mcmullan, J. A. Parish

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

The most promising varieties in last year's trials were the 2 row crossbreds W44 and W45 and the 6 row white grained variety Atlas 57.

BARLEY variety trials were located on four Research Stations and on farmers' properties at Northampton, Tammin and Mt. Barker. Brief details of the characteristics of the varieties and crossbreds under test were given in a previous article.

Barley Variety Trials, 1962 And 1963, J L. Mcmullan

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

TO ASSESS their yielding ability and grain quality, varieties of barley are grown each year by the Department of Agriculture.

The trials are located on Research Stations in the cereal-growing areas.

THE State Wheat Advisory Committee has prepared recommendations for wheat varieties for 1966 sowings.

Early Pollen Forcing In A White X Black Spruce Hybrid And Its Parental Species, Lawson L. Winton

Journal of the Minnesota Academy of Science

Viable pollen was successfully forced from winter-collected cuttings of white and black spruce, as well as of a hybrid of them. The natural time difference in flowering was overcame, thus providing a tool for interbreeding these species. During forcing, and naturally on the trees, pollen always shed from white spruce first, then the hybrid and finally from black spruce. Using departures from long-range weather averages, a heat-requirement difference was postulated for each species to account for the time difference in their flowering.

The Naturalised And Cultivated Annual Medics Of Western Australia, B J. Quinlivan

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

IT is not many years since the term pasture improvement in Western Australia was synonymous with one species only, subterranean clover.

The amazing adaptability of this species to the environment enabled it to be grown in a wide range of rainfall conditions and in many different districts.
