Monosomic Analysis of Leaf Rust Reaction, Awnedness, Winter Injury and Seed Color in Pawnee Wheat¹

Abstract

HE: use of monosomic plants offers a special method of cies. Investigations utilizing monosomic types in common wheat. Triticum vulgare Vill., were initiated at Kansas State College in 1947. This report deals .with the results of crosses with 16 different monosomics of Chinese spring wheat crossed to Pawnee winter wheat for a study of the inheritance of leaf rust reaction, awn expression, winter injury, and seed color.

Distribution of Necrosis Genes in Wheat

“…Due to winter hardiness contributed by this gene (Heyne and Livers 1953), the 6x spelt derivative may have eventually taken over an entire field, thus establishing itself as a new crop species. Origin of T, macha : In distribution of chlorosis genes, Tsunewaki and Kihara (1962) have reported that all of seven Ae.…”

Chromosomes Associated With Waxlessness, Awnedness and Time of Maturity of Common Wheat

“…5075 that modifies the B2 locus and results in increased awnedness. This may be identical Disomic to the gene for awn production located on chronlosome 3D by Heyne and Livers (1953) in the variety Pawnee.…”

Identification of Chromosomes Carrying Genes for Resistance to Race 15, 122 and 34 of Stem Rust (Puccinia Graminis Tritici) In Wheat VarietyYaqui-53

“…770 (SINGH and SWAMINATHAN 1960). The usefulness of aneuploids in determining the mode of inheritance of rust resistance in varieties of bread wheat has already been demonstrated by various workers (HEYNE and LIVERS 1953;PLESSERS 1954;RonENHISER 1948 andSEARS et al 1957, etc.). The present study was hence undertaken to locate, by monosomic analysis, the chromosome or chromosomes of the wheat variety Yaqui-53 (E. 2842) on which genes for resistance to some races of stem rust are situated.…”
