Wheat Variety Trials On Research Stations, J T. Reeves, J. L. Mcmullan

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

THE results of wheat variety trials at seven Research Stations in the medium and low rainfall areas for the years 1957, 1958 and 1959 are presented and discussed.

The trials are designed to give information on yield and flour quality of promising crossbreds originating from local breeding programmes and newly produced varieties from other parts of Australia.

Large scale variety trials are the final tests in the long process of selection and testing which is essential before a new crossbred can be released.

The new wheats are compared with standard ones under different conditions of soil and climate.

Genetic Studies Of Winter Hardiness In Barley, C. R. Rohde, C. F. Pulham

Nebraska Agricultural Experiment Station: Historical Research Bulletins

An important obstacle toward the development of winter barley varieties with a higher level of winter hardiness has been the deficiency of genetic information on this character. The primary objective of these studies was to obtain information on the genetics of the winter hardiness of a group of 18 winter barley varieties which originated from widely different geographic areas of the world. It was hoped that this information might be helpful in determining whether or not it would be possible for barley breeders to combine different genetic sources of winter hardiness and attain a higher level of hardiness than presently …

Some Factors Affecting The Baking Quality In Wheat, A R. Egan

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

ALTHOUGH between 10 per cent, and 15 per cent, of wheat consumed in Australia is used in feed for domestic animals, the primary usage in home consumption is for bread-making.

Exports, which account for roughly 75 per cent, of the normal Australian crop, are also mainly used in bread-making.

Origin And Performance Of Ranger Alfalfa, W. R. Kehr

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Ranger alfalfa was developed through the cooperative efforts of personnel of the United States Department of Agriculture and the Nebraska Agricultural Experiment Station and released for seed increase in 1940. It is a winter-hardy, bacterial wilt resistant variety synthesized from five basic strains selected from Cossack, Turkistan and Ladak. Breeding methods used in the development of this variety were described in detail. Research results obtained on the performance of the basic strains and on the seed lots, produced under certification procedures, in controlled wilt and cold tests and forage yield trials under field conditions at the Nebraska station were presented …

The Effect Of Inbreeding Diallel Crosses Of Inbred Lines Of Corn Selected For High And Low Combining Ability, Melvin Dale Rumbaugh

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The present day hybrid seed corn industry is based upon the development and utilization of inbred lines in hybrid combination. Current breeding procedures are largely predicated on the assumption that the actions of complementary, dominant or partially dominant favorable genes are responsible for the heterosis observed in the hybrids produced. If heterosis were due in considerable part to nonallelic interactions or to overdominance, the present breeding procedures might be expected to yield superior hybrids but would not be highly efficient.

Since the proposal of complementary growth factors as a genetic explanation of heterosis and the alternative proposal of physiological stimulation …

Inheritance Of Sterility, Flower Color, Spinelessness, Attached Pappus And Rust Resistance In Safflower, Carthamus Tinctorius, Carl E. Claassen

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Since literature pertaining to breeding and inheritance in safflower was found to be very limited, fundamental research was instituted to determine: (A) a method for making controlled crosses, (B) the amount of natural crossing that occurs, (C) the association of oil content of seed with other seed and plant characteristics, and (D) the mode of inheritance of sterility, flower color, spinelessness, attached pappus and rust resistance. Results on natural and controlled crossing in safflower and the association of oil content in seed with other plant and seed characteristics have been reported. It is the purpose of this bulletin to report …

Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The plant breeder is initially concerned with gaining a knowledge of the breeding behavior of his plant materials in order that improvement may be undertaken effectively. It is important to know the different characteristic pollination habits of these plants. To develop and apply techniques applicable to the improvement of a given grass crop, it is desirable to know the time of day and the number of days that the grass sheds pollen. The effects of temperature, humidity, light, and wind on pollination must be considered. Once superiority of germplasm is obtained, the most important consideration is the maintenance of this …

Alfalfa Breeding, H. M. Tysdal, T. A. Kiesselbach, H. M. Westover

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Interest in the principles of alfalfa breeding has increased greatly with the growing "forage consciousness" of the country at large and the more specific interest developed through cooperation in the Alfalfa Improvement Conference. As is true of many other forage crops, information on the breeding behavior of alfalfa is meager. During the past few years, however, the genetics and principles of reproduction of this crop have come to be better understood and it is the purpose of this paper to bring together the available information pertaining to the improvement of alfalfa and to add certain suggestions with respect to future …

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 …

The Immediate Effect Of Gametic Relationship And Of Parental Type Upon The Kernel Weight Of Corn, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This investigation to determine the relation of the kernel weight of corn to the source of pollen with which it was fertilized has been made to answer several questions of both practical and technical interest: (1) To what extent is kernel weight affected in the current crop by the "breadth of breeding" or the gametic relationship? (2) What is the relation of the diversity of parental type to the immediate effect of foreign pollen upon the kernel weight of corn? (3) Is the immediate effect of cross-fertilization upon the kernel weight of sufficient importance to justify the annual mixing of …

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.

Bulletin 105 - Pedigree Selection Of Seed At The Chapman And Merredin Experiment Farms, Geo L. Sutton

Bulletins 1 - 2999

A Paper read before the Royal Society of the Royal Society of Western Australia, 12th October,1921.

"Pedigree" or "Pure Line" selection is that system of selection under which the choice is made, not. solely because of the attractive appearance of the plant, but because of its ability to transmit its good qualities to the progeny. Such a system requires, and the method of selection ensures, that the qualities sought after shall be hereditary. For this purpose a record of ancestry is essential, hence the use of the term "pedigree."
