The evaluation of heterosis for grain yield, total leaf area and malting quality in 21 spring barley crosses

Creator:

Carleton, A. E. (Albert Eugene), 1940-

Abstract:

The purpose of this study was to determine the amount of heterosis in three complex traits in barley and to investigate the concept of component interaction as a means of producing heterosis. The complex traits were grain yield, total leaf area, and malting quality. Seven varieties of spring barley were...

The effect of heterozygosity on phenotypic stability in spring barley

Creator:

Smith, Garry Austin

Abstract:

The effect of heterozygosity on the phenotypic stabilities of six morphological plant characteristics was studied in hybrid crosses of two self-pollinated barley species Hordeum vulgare L., emend Lam. and Hordeum distichum L., emend Lam. Experimental material consisting of parents and their F₁ diallel progeny were grown at two field locations...

Inheritance of resistance to barley yellow dwarf virus disease in barley

Creator:

Sieveking, William Earl, 1932-

Abstract:

Studies were conducted on artificially infected susceptible and resistant barley varieties in an attempt to determine the effect of barley yellow dwarf virus on the growth and development of these plants. A resistant and a susceptible variety were infected at four stages of growth and harvested at two stages. Roots,...
