Data from advanced breeding experiments between 1985 and 1994 were used to determine the effects of region, year environment on quality canola grown across Victoria. Estimates these unbalanced data made using residual maximum likelihood. Environmental large relative cultivar for oil protein content, while reverse occurred glucosinolate content. High contents (and low seed contents) correlated with cooler spring temperatures higher rainfall. Oil lowest, average, in dry years, or hotter...
Blackleg disease, caused by the fungus Leptosphaeria maculans, is major disease of canola (Brassica napus) worldwide. A set 12 Australian L. maculans isolates was developed and used to characterise seedling resistance in 127 cultivars advanced breeding lines. Plant mortality data assess effectiveness growing regions Australia showed that Rlm3 Rlm4 genes were less effective than other genes. This finding consistent with regional surveys pathogen, which frequency Rlm4-attacking >70% fungal...
Blackleg disease (phoma stem canker) of Brassica napus (canola, oilseed rape) is caused by the fungus Leptosphaeria maculans . In some regions Australia, resistance in rape cultivars derived from B. rapa subs sylvestris (e.g. cv. Surpass 400) became ineffective within three years commercial release. The genetic control avirulence L. towards 400 described. When Australian field isolates were screened on this cultivar, phenotypic classes observed; virulent, intermediate and avirulent. Analysis...
Blackleg disease (phoma stem canker) caused by the fungus Leptosphaeria maculans is a major of canola (oilseed rape, Brassica napus ) worldwide. Canola plants in pots were exposed to blackleg‐infested stubble with different complements resistance genes and then assessed for disease. Plant mortality was reduced when from cultivar complement compared same gene. These findings consistent 7 years field surveys, which showed that changes selection pressure as result extensive sowing cultivars...
The oilseed Brassica juncea is an important crop with a long history of cultivation in India and China. Previous studies have suggested polyphyletic origin B. more than one migration from the primary to secondary centers diversity. We investigated molecular genetic diversity based on 99 simple sequence repeat markers 119 varieties China, India, Europe, Australia test whether differentiation follows Vavilov's proposal Two distinct groups were identified by A genome, same two confirmed B...
Due to the large increase of canola production in Australia, current blackleg cultural control recommendations (extended rotation length and isolation distance from stubble) are not adhered by farmers many canola-producing regions. Canola crops increasingly being sown short and, instances, adjacent paddocks containing stubble. In this study, level disease commercial was determined for different rotations distances There a strong relationship between presence stubble previous year...
Sclerotinia stem rot (SSR) is a significant agricultural problem worldwide. Finding sources of resistance crucial to the ongoing search for better management this disease. Brassica germplasm from Australia, China and India was screened SSR under Western Australian field conditions following inoculation, application spray mycelial suspension, or as consequence myceliogenic germination originating sclerotia resident in soil. Significant differences response were observed among 53 genotypes...
Genomic selection accelerates genetic progress in crop breeding through the prediction of future phenotypes candidates based on only their genomic information. Here we report correlations and accuracies 22 agronomic, disease, seed quality traits measured across multiple years (2015–2017) replicated trials under rain-fed irrigated conditions Victoria, Australia. Two hundred two spring canola lines were genotyped for 62,082 Single Nucleotide Polymorphisms (SNPs) using transcriptomic...
Vernalization periods ranging from 0 to 11 weeks at 4 °C were used study the reproductive development of four near-isogenic lines wheat (Triticum aestivum L. em. Thell). From results for days anthesis two types gene action identified, a threshold (all-or-nothing) response (vrn3 and/or vrn4) and cumulative (graded) (vrn1). The another (vrn2) intensified these responses. Based on genes, model relating genotype was derived. Final leaf number shown be closely related after adjusting differences...
Innovation has been integral in the development of current Australian canola (Brassica napus L.) industry. From initial introduction poorly adapted Canadian germplasm, breeders have developed high yielding, quality, disease-resistant cultivars. The industry transitioned from being reliant on imports to becoming one world’s major exporters canola. This review details progressive innovations breeding programs rapeseed more recent developments including herbicide resistance, hybrid cultivars,...
Genomic prediction is becoming a popular plant breeding method to predict the genetic merit of lines. While some genomic results have been reported in canola, none evaluated for blackleg disease. Here, we report seedling emergence, survival rate, and internal infection), using 532 Spring Winter canola These lines were phenotyped two replicated disease nurseries grown at Wickliffe Green Lake, Victoria, Australia. A transcriptome genotyping-by-sequencing approach revealed 98,054 single...
Australian canola (Brassica napus L.) has been relatively isolated from the global gene pool and limited knowledge is available for genetic variability based on DNA profiling. In present study, diversity of recent cultivars was determined by simple sequence repeat (SSR) marker analysis. total, 405 individuals 48 varieties were genotyped with 18 primer pairs, resulting in 112 polymorphic features. The number features amplified each SSR pair varied 3 to 16. Analysis molecular variance (AMOVA)...
White rust (Albugo candida) is a highly destructive disease of oilseed Brassicas such as Brassica juncea and B. rapa. Most commercial or rapa varieties are susceptible yield losses from combined infection leaves inflorescences can be up to 20% 60% in Australia India, respectively. In Australia, canola-quality has been developed extend production into lower rainfall areas, with the first variety planned for release 2006. It essential identify useful sources host resistance breeding and/or...
A range of Brassica species was screened for resistance to Leptosphaeria maculans, the causal agent blackleg. The lines were assessed in 8 disease nurseries 4 canola growing regions Australia and 1�glasshouse trial, with a view identifying alternative sources L. maculans Australian breeding programs. Lines degree internal external blackleg symptoms during both seedling adult plant growth stages. Correlation ranking between very strong (0.41-0.98). carinata B. nigra most resistant nurseries,...
