White lupin (Lupinus albus L.) is an important grain legume crop in Australia. The anthracnose incursion in the mid-1990s wiped out the white lupin industry in Western Australia (WA). Since then, incorporation of anthracnose resistance has been a major focus in white lupin breeding. After a series of experiments and targeted breeding in WA, high-yielding anthracnose-resistant genotypes were developed. One of these lines, Amira, was released in 2012 as a replacement for the then-benchmark variety Andromeda. Amira is high-yielding and early-maturing and it has substantially improved resistance to anthracnose compared with Andromeda. Its yield and grain quality are similar to Kiev Mutant and it will be suitable for growing in parts of the Northern Agricultural Region of WA where anthracnose risk is moderate to low. With the adoption of this new variety, reliable production of white lupin can recommence in WA. The growing season in WA is characterised by terminal drought, and early flowering is as important as anthracnose resistance. However, combining these traits was difficult and their combination was not achieved at a desired level in earlier work. The incorporation of the early-flowering trait from a different genetic source from France demonstrated that it is possible to combine these traits at an appropriate level. There was no genetic linkage between the two traits, and consequently, new genotypes with earlier phenology and higher levels of resistance than Amira were developed. The combination of early flowering and anthracnose resistance represents a breakthrough that will significantly improve the adaptation and profitability of white lupin production in WA.

Abstract White lupin (Lupinus albus L.) is a high-protein grain legume crop, grown since ancient Greece and Rome. Despite long domestication history, its cultivation remains limited, partly because of susceptibility to anthracnose. Only some late-flowering, bitter, low-yielding landraces from Ethiopian mountains displayed resistance to this devastating disease. The resistance is controlled by various genes, thereby complicating the breeding efforts. The objective of this study was developing tools for molecular tracking of Ethiopian resistance genes based on genotyping-by-sequencing (GBS) data, envisaging linkage mapping and genomic selection approaches. Twenty GBS markers from two major quantitative trait loci (QTLs), antr04_1/antr05_1 and antr04_2/antr05_2, were converted to PCR-based markers using assigned transcriptome sequences. Newly developed markers improved mapping resolution around both anthracnose resistance loci, providing more precise QTL estimation. PCR-based screening of diversified domesticated and primitive germplasm revealed the high specificity of two markers for the antr04_1/antr05_1 locus (TP222136 and TP47110) and one for the antr04_2/antr05_2 locus (TP338761), highlighted by simple matching coefficients of 0.96 and 0.89, respectively. Moreover, a genomic selection approach based on GBS data of a recombinant inbred line mapping population was assessed, providing an average predictive ability of 0.56. These tools can be used for preselection of candidate white lupin germplasm for anthracnose resistance assays.

Lupinus Albus L

White lupin (Lupinus albus L.) is a pulse annual plant cultivated from the tropics to temperate regions for its high-protein grain as well as a cover crop or green manure. Wild populations are typically late flowering and have high vernalization requirements. Nevertheless, some early flowering and thermoneutral accessions were found in the Mediterranean basin. Recently, quantitative trait loci (QTLs) explaining flowering time variance were identified in bi-parental population mapping, however, phenotypic and genotypic diversity in the world collection has not been addressed yet. In this study, a diverse set of white lupin accessions (n = 160) was phenotyped for time to flowering in a controlled environment and genotyped with PCR-based markers (n = 50) tagging major QTLs and selected homologs of photoperiod and vernalization pathway genes. This survey highlighted quantitative control of flowering time in white lupin, providing statistically significant associations for all major QTLs and numerous regulatory genes, including white lupin homologs of CONSTANS, FLOWERING LOCUS T, FY, MOTHER OF FT AND TFL1, PHYTOCHROME INTERACTING FACTOR 4, SKI-INTERACTING PROTEIN 1, and VERNALIZATION INDEPENDENCE 3. This revealed the complexity of flowering control in white lupin, dispersed among numerous loci localized on several chromosomes, provided economic justification for future genome-wide association studies or genomic selection rather than relying on simple marker-assisted selection.

Lupinus Albus L

The lupine is very sensitive to the different ecological conditions. The examinations of lupine was started in 2003 and our aim is determine yield components which directly affecting crop yields (flower, pod and seed number per plants) in different sowing times (3 times, two weeks apart) and growing area area (240, 480, 720 cm2) combinations. According to our results the sowing times, the growing area and the meteorological conditions are influence on yield significantly. Our data suggest that the early sowing and large growing area combination is favourable to rate of fertilized plants and to development of yield. Later sowing reduces the seed yield depending on the cropyear. In our experiment, the decrease of yield was in the unfavourable year (2003) 20–96%, and in the most favourable meteorological conditions (2004) 10–79%, and in rich rainfall year (2005) 15–88%.

Hg Accumulation

Two white lupin (Lupinus albus L.) cultivars were tested for their capacity to accumulate mercury when grown in Hg-contaminated soils. Plants inoculated with a Bradyrhizobium canariense Hg-tolerant strain or non-inoculated were grown in two highly Hg-contaminated soils. All plants were nodulated and presented a large number of cluster roots. They accumulated up to 600 μg Hg g−1 DW in nodules, 1400 μg Hg g−1 DW in roots and 2550 μg Hg g−1 DW in cluster roots. Soil, and not cultivar or inoculation, was accountable for statistically significant differences. No Hg translocation to leaves or seeds took place. Inoculated L. albus cv. G1 plants were grown hydroponically under cluster root-promoting conditions in the presence of Hg. They accumulated about 500 μg Hg g−1 DW in nodules and roots and up to 1300 μg Hg g−1 DW in cluster roots. No translocation to the aerial parts occurred. Bioaccumulation factors were also extremely high, especially in soils and particularly in cluster roots. To our knowledge, Hg accumulation in cluster roots has not been reported to date. Our results suggest that inoculated white lupin might represent a powerful phytoremediation tool through rhizosequestration of Hg in contaminated soils. Potential uptake and immobilization mechanisms are discussed.
