Relationship among leaf (Puccinia recondita Roberge ex Desmaz f. sp. tritici) and yellow (Puccinia striiformis Westendorp. f. sp. tritici) rust resistance and some agro-morphologic traits in wheat hybrids at seedling stage.
This research was carried out to determine if dominant morphological traits can be use instead of the rust resistance tests as marker characters for some agro-morphologic traits both leaf (Puccinia recondita Roberge ex Desmaz. f. sp. tritici.) and yellow rust (Puccinia striiformis Westendorp f. sp. tritici) disease. For this, 13 wheat parent (4 are T. durum Desf. and 9 are T. aestivum L.) were used and three main agro-morphologic traits (Namely, Leaf Colour (LC) (Dark and light green, Dg and Lg, relatively); Auricle Colour (AC) (White and Red, Wh and Re, relatively) and Leaf Waxiness (LW) (Waxy and Non waxy, Wx and Nw, relatively) were investigated at the seedling stage. They were found as dominant and concluded that investigated traits could be used as a morphological marker character for the leaf and yellow rust disease resistance tests under greenhouse conditions without doing complex and risky rust tests. And determined that, these traits may be use effectively without doing the complex rust tests in the limited populations or for the pre-selections. Doing with this, it will be bring a great accuracy, successful, correction and speed to the rust disease studies and provides important and valuable information for the plant breeders and pathologists. In addition, knowing of the resistance type (genetic mechanism etc.) in wheat facilitates it will be make to find out the suit and most appropriate breeding and selection methodology/methodologies.
