| Abstract/Contents: | "An overhead irrigation technique was used from June to August 2015 to screen 403 perennial ryegrasses (Lolium perenne L.) genotypes (3 replicates per genotype) for salinity tolerance. The tolerance of a given genotype was visually assessed according to green color retention when exposed to increased levels of soil salinity. Salinity tolerant (n = 20) and sensitive (n = 9) genotypes were identified as candidate parental lines and transplanted into a field nursery on 24 September 2015. Parental candidates were visually evaluated for leaf color and growth habit morphology during May 2016. Simultaneously, candidate genotypes were maintained in a separate spaced plant nursery where they were screened for resistance to dollar spot, a foliar disease caused by the fungal pathogen Sclerotinia homoeocarpa F.T. Bennett. In addition to phenotypic evaluations, variability of genetic backgrounds in candidate parental lines was also assessed by genotyping with 24 microsatellite DNA markers. Parental lines were isolated, in pairs, based on flowering compatibility and contrasting phenotypic traits. Fourteen biparental crosses were conducted from late May to early July 2016. Seed was harvested from both parents in all biparental crosses and threshed on 22 August 2016. The biparental cross I × A89, was chosen for the mapping population as determined by variation in phenotypes and polymorphism of genetic backgrounds. Seed from the I × A89 cross was planted on 22 August 2016 and plantlets were transplanted on 14 September 2016 to establish the mapping population. The I × A89 mapping population consists of the two parents (15-8325-I and 15-8343-A89)and 368 progeny (184 progeny from each parent) and will be useful for genetic studies of important traits in perennial ryegrass breeding." |
