Quantitative genetic analysis of grain yield in an Australian Brassica napus doubled-haploid population

Abstract: High yield is a major objective in canola-breeding programs. We analysed the genetic determinants controlling variation in grain yield in a doubled-haploid (DH) breeding population derived from a single BC1F1 plant from the cross Skipton/Ag-Spectrum//Skipton (designated as the SAgS population). DH lines were evaluated for flowering time and yield in two replicated trials and exhibited significant genetic variation for both traits. Yield showed negative correlation with flowering time; lines that flowered earli… Show more

“…Pair-plots showing genetic correlation of EBLUPS (empirical best linear unbiased estimators) from the univariate analysis of flowering time and grain yield among 144 doubled haploid lines of B. napus population derived from Skipton/Ag-Spectrum//Skipton. DH lines were grown across 4 phenotypic environments (2013-2016) in field plots, 2013 at Euberta, NSW, Australia; 2014 at Wagga Wagga, NSW, Australia (Raman et al 2016), 2015 and 2016 at the Wagga Wagga (this study).…”

“…1). Despite of extended photoperiod at 20°C, several accessions did not flower under CE conditions suggesting that these accessions require vernalisation and flowered when exposed to extended periods of cold temperatures (Raman et al 2016). In order to have a minimum effect of vernalisation on flowering time, all field trials were conducted in the middle of June (instead of April –the main canola growing season in Australia); we identified a highly significant QTL close to FT locus on chromosome A02, as identified under CE conditions in LD conditions, suggesting that FT is a major candidate for flowering time across different growing conditions (Fig 4).…”

“…DArTseq markers having <80% call rate, and <5% MAF were discarded prior to linkage analysis. A set of 18,851 DArTseq-SNPs and silico DArTs that showed segregation among DH lines was selected for genetic linkage map construction as described in 31 . QTL analysis involved taking the statistical models for phenotypic data and partitioning DH line genetic variation into variation due to putative QTL and polygenic variation.…”
