Inheritance Of Resistance To Six Races Of Bunt, To Awns And Kernel Color In A Wheat Cross, Marr D. Simons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is the most important cereal crop of the world, and one of the most serious diseases affecting it over much of its range is covered smut or bunt (57). The word "bunt", according to Heald (48), is a contraction of an old English term, "burnt ear", which fittingly describes the ravages of covered smut.

Man's first knowledge of this disease is lost in antiquity, but it was first recorded by early Greek writers (97). Gaines (39), writing in 1928, stated that since 1924 stinking smut had been the most destructive parasite of wheat in America, causing losses of as …

Inheritance Of Resistance To Races Of Covered Smut, Awns, And Chaff Color In A Wheat Cross, Nazar Singh Dhesi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is the most important cereal crop in the world. It is the principal staple food in Russia, United States, China, Canada, India and a number of other countries.

Covered smut is one of the most serious disease of wheat all over the world. According to Woolman and Humphrey (82) it was known from very early times and is referred to by Theoprastus and other early Greek Roman writers.

Inheritance Of Glume And Kernel Color, Of Awnedness, And Of Spike Density In A Cross Between Ridit And Sevier Wheat, Leslie W. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper is devoted principally to the presentation and discussion of the results obtained when certain contrasting characters were brought together in a wheat cross between Ridit and Sevier 59. this is one of the crosses made in an attempt to develop a wheat adapted to this region with the following desirable qualities: Bunt resistance, strong straw, hard kernels, and heavy yield. How near this ideal is approached in succeeding generations can be told only by extensive tests. The genetic study herein presented was made to hasten the time when some of the progeny of this cross may become of …

Inheritance In A Wheat Cross Of Ridit X Utac, C. Leland Dalley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Present-day plant breeding, on the foundation made many years ago, has achieved important scientific and economic results. By means of introductions and selections, superior strains such as Turkey and Kanred have been obtained. Through hybridization new combinations of characters result, combining desirable characters of different plant types in a single individual. In this program, wheat hybridization has occupied a worthy place.

Each year a number of wheat crosses are made at the Utah Experiment Station, the main purpose of which is to develop superior strains of wheat. Such an economic program is aided and hastened by studies in genetic behavior. …

Inheritance Of Awns In A Cross Between Hard Federation And Kota Wheats, B. Ira Judd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past few years there have been numerous studies made of various characters in wheat. Some characters which were thought at first to be simple in inheritance have since been found to be rather complex.

The data in the following pages are the results of an investigation made to study the inheritance of awns in a cross between Hard Federation and Kota varieties of wheat.
