Exploring and exploiting variety by environment (V × E) interaction is one of the major challenges facing plant breeders. In paper I of this series, we presented an approach to modelling V × E interaction in the analysis of complex multi-environment trials using factor analytic models. In this paper, we develop a range of statistical tools which explore V × E interaction in this context. These tools include graphical displays such as heat-maps of genetic correlation matrices as well as so-called E-scaled uniplots that are a more informative alternative to the classical biplot for large plant breeding multi-environment trials. We also present a new approach to prediction for multi-environment trials that include pedigree information. This approach allows meaningful selection indices to be formed either for potential new varieties or potential parents.

Insight Into

: Oilseed brassicas stand as the second most valuable source of vegetable oil and the third most traded one across the globe. However, the yield can be severely affected by infections caused by phytopathogens. White rust is a major oomycete disease of oilseed brassicas resulting in up to 60% yield loss globally. So far, success in the development of oomycete resistant Brassicas through conventional breeding has been limited. Hence, there is an imperative need to blend conventional and frontier biotechnological means to breed for improved crop protection and yield. : This review provides a deep insight into the white rust disease and explains the oomycete-plant molecular events with special reference to Albugo candida describing the role of effector molecules, A. candida secretome, and disease response mechanism along with nucleotide-binding leucine-rich repeat receptor (NLR) signaling. Based on these facts, we further discussed the recent progress and future scopes of genomic approaches to transfer white rust resistance in the susceptible varieties of oilseed brassicas, while elucidating the role of resistance and susceptibility genes. Novel genomic technologies have been widely used in crop sustainability by deploying resistance in the host. Enrichment of NLR repertoire, over-expression of R genes, silencing of avirulent and disease susceptibility genes through RNA interference and CRSPR-Cas are technologies which have been successfully applied against pathogen-resistance mechanism. The article provides new insight into Albugo and Brassica genomics which could be useful for producing high yielding and WR resistant oilseed cultivars across the globe.

Anatomical features of the siliqua valve and suture were studied in 13 Brassica accessions representing B. napus, B. campestris and B. juncea in order to investigate the basis of shatter-resistance and the mechanism of shattering (dehiscence). The high level of shatter-resistance of certain accessions of B. campestris var. Yellow Sarson and var. Brown Sarson was associated with the absence of an abscission (separation) layer in the region of attachment of the siliqua valve to the replum. There were no differences in this regard between intermediate shattering and shatter-susceptible accessions; both these types had a completely developed abscission layer. Orientation of the tissue and of the microfibrils of the cells of the siliqua valve did not differ between different layers of the valve in any of the accessions studied. This implied that the forces giving rise to dehiscence (shattering) are unlikely to develop within the siliqua and thus the mechanism of dehiscence is most likely passive.
