High temperature (heat) stress during grain filling is a major problem in most of the wheat growing areas. Developing heat tolerant cultivars has become a principal breeding goal in the Southern and Central Great Plain areas of the USA. Traits associated with high temperature tolerance can be used to develop heat tolerant cultivars in wheat. The present(More)
To study the cytoplasmic effects on heat tolerance, the nuclear genomes of ten alloplasmic lines were substituted by four or five backcrosses using ‘Karl 92’, ‘Ventnor’, ‘U1275’ and ‘Jagger’ as the recurrent parent. During the final backcross, reciprocal crosses were made to develop cytoplasmic near isogenic lines. Sixty-eight BC5F1/BC4F1 lines and their(More)
