Phytophthora root rot (PRR) of chickpea () caused by is an important disease. Partial resistance to PRR is sourced from . In this study, we evaluated if lines with low levels of PRR foliage symptoms in two contrasting recombinant inbred line (RIL) populations parented by chickpea cultivars (Yorker and Rupali) and 04067-81-2-1-1 (, interspecific breeding line) had a significant drag on yield parameters.

root rot caused by is an important disease of chickpeas () in Australia with limited management options, increasing reliance on breeding for improved levels of genetic resistance. Resistance based on chickpea- crosses is partial with a quantitative genetic basis provided by and some disease tolerance traits originating from germplasm. Partial resistance is hypothesised to reduce pathogen proliferation, while tolerant germplasm may contribute some fitness traits, such as an ability to maintain yield despite pathogen proliferation.

Tolerance to the cereal disease Fusarium crown rot (FCR) was investigated in a set of 34 durum wheat genotypes, with Suntop, (bread wheat) and EGA Bellaroi (durum) as tolerant and intolerant controls, in a series of replicated field trials over four years with inoculated (FCR-i) and non-inoculated (FCR-n) plots of the genotypes. The genotypes included conventional durum lines and lines derived from crossing durum with 2-49, a bread wheat genotype with the highest level of partial resistance to FCR. A split plot trial design was chosen to optimize the efficiency for the prediction of FCR tolerance for each genotype.
