Inheritance of Septoria leaf blotch resistance and the possible influence of heading date and plant height on the disease expression in a winter wheat cross

Creator:

Camacho Casas, Miguel Alfonso

Abstract:

Parental lines, Fi's and segregating populations (F₂, F₃ and BC's) including reciprocals were evaluated under field conditions to determine if genetic resistance per se exists for Septoria Leaf Blotch in a selected winter wheat cross. The experiment was conducted over a three year period with both natural infection and artificial...

Modifying selected factors to classify levels of resistance or tolerance in wheat to Septoria Tritici Blotch

Creator:

Re, Jose Vicente

Abstract:

Influence of abiotic and biotic factors were examined in selected winter wheats previously identified as representing a range of responses to septoria infection. In the greenhouse two and three inoculations identified resistance when disease severity was assessed either for the top four leaves or the flag leaf respectively. Kernel number...
