Physiologic Races

The occurrence in Brazil of physiologic races of loose smut, Ustilago tritici, (Pers.) Rostr., has been demonstrated. Twelve races were identified amongst 50 field collections of loose smut. Five of the races were classified as being similar to Canadian race T 2, and two races as T 8 when the standard set of differential cultivars was used. However, further differentiation of these races was possible on three supplemental differentials. Another four races were virulent on several differential cultivars of common wheat and on Pentad, a differential cultivar of durum wheat, and thus appear to invalidate the claim that formae speciales of Ustilago tritici exist on common wheat and on durum wheat.

Twenty-seven lines of triticale (Triticale hexaploide Lart.) were inoculated with a mixture of races T1 to T5 of loose smut of wheat (Ustilago tritici (Pers.) Rostr.); six lines were susceptible with the level of infection ranging up to 67%. The race virulent on three of the lines was found to be T4, a race characterized by virulence on cultivars of durum wheat (Triticum turgidum L.). Of 119 cultivars of spring rye (Secale cereale L.) that were inoculated with the mixture of races, 68 were infected. The races virulent on five cultivars were found to be T2 on four, and T4 on one. The level of infection ranged up to 37%.

AbstractThe genetic improvement of durum wheat and enhancement of plant performance often depend on the identification of stable quantitative trait loci (QTL) and closely linked molecular markers. This is essential for better understanding the genetic basis of important agronomic traits and identifying an effective method for improving selection efficiency in breeding programmes. Meta-QTL analysis is a useful approach for dissecting the genetic basis of complex traits, providing broader allelic coverage and higher mapping resolution for the identification of putative molecular markers to be used in marker-assisted selection. In the present study, extensive QTL meta-analysis was conducted on 45 traits of durum wheat, including quality and biotic and abiotic stress-related traits. A total of 368 QTL distributed on all 14 chromosomes of genomes A and B were projected: 171 corresponded to quality-related traits, 127 to abiotic stress and 71 to biotic stress, of which 318 were grouped in 85 meta-QTL (MQTL), 24 remained as single QTL and 26 were not assigned to any MQTL. The number of MQTL per chromosome ranged from 4 in chromosomes 1A and 6A to 9 in chromosome 7B; chromosomes 3A and 7A showed the highest number of individual QTL (4), and chromosome 7B the highest number of undefined QTL (4). The recently published genome sequence of durum wheat was used to search for candidate genes within the MQTL peaks. This work will facilitate cloning and pyramiding of QTL to develop new cultivars with specific quantitative traits and speed up breeding programs.

Fungal diseases pose a potential threat to successful cereal production in wheat particularly in Pakistan. Loose smut caused by Ustilago tritici is an important disease of wheat. During the current research various lines of wheat were screened against the deadly disease, results showed no line was resistant against the disease in the wheat genetic resources, mostly varieties showed susceptible to highly susceptible response. All the environmental variables were found conducive for the development of the disease. The disease is a serious concern for wheat production and potential breeding programs are the need of time to cater the losses due to this disease.
