Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:

Camacho Casas, Miguel Alfonso

Abstract:

The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates.

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...
