Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:

Baltazar, Baltazar

Abstract:

Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

Genetic diversity and interactions in populations of plants and pathogens

Creator:

Knott, Elizabeth A.

Abstract:

Two experiments involving interactions between wheat (Triticum aesitivium L.) cultivars and rust pathogens were investigated. One experiment evaluated the aggressiveness (measured by infection efficiency and latent period) of populations of Puccinia recondita Rob. when inoculated on the cultivar they were isolated from, their "own" cultivar, and when inoculated onto other...

probably due in part to differences in height and disease resistance of the cultivars involved. However
