“…Based on the support vector machine method developed by Vapnik (1995), support vector machine regression (SVMR) was initially applied to plant breeding by Maenhout et al (2007). The main objective of SVMR is to minimize prediction error (Long et al 2011).…”

Evaluation of genomic selection and marker-assisted selection in Miscanthus and energycane

Although energycane (Saccharum spp. hybrids) is widely used as a source of lignocellulosic biomass for bioethanol, breeding this crop for disease resistance is challenging due to its narrow genetic base. Therefore, efforts are underway to introgress novel sources of genetic resistance from Miscanthus into energycane. Given that disease resistance in energycane could be either qualitative or quantitative in nature, careful examination of a wide variety of genomicenabled breeding approaches will be crucial to the success of such an undertaking. Here we examined the efficiency of both genomic selection (GS) and markerassisted selection (MAS) for traits simulated under different genetic architectures in F 1 and BC 1 populations of Miscanthus × Miscanthus and sugarcane × sugarcane crosses. We observed that the performance of MAS was comparable and sometimes superior to GS for traits simulated with four quantitative trait nucleotides (QTNs). In contrast, as the number of simulated QTN increased, all four GS models that were evaluated tended to outperform MAS, select more phenotypically optimal F 1 individuals, and accurately predict simulated trait values in subsequent BC 1 generations. We therefore conclude that GS is preferable to MAS for introgressing genetic sources of horizontal disease resistance from Miscanthus to energycane, while MAS remains a suitable option for introgressing vertical disease resistance.

Survey of the Bru1 gene for brown rust resistance in Brazilian local and basic sugarcane germplasm

et al. 2017

Bru1 is currently the major gene conferring brown rust resistance in sugarcane, and diagnostic markers are available. A survey for the presence of this gene was conducted on 391 genotypes including Brazilian cultivars, clones and basic germplasm. The efficiency of these markers for identifying resistant cultivars and artificially inoculated basic germplasm was also evaluated. The Bru1 frequency among cultivars (73.5%) suggests this gene is the prevalent source of brown rust resistance in Brazilian sugarcane breeding programmes. Most of the cultivars known to be resistant were positive for Bru1, although other genes for resistance could be present in lines not having Bru1. Only 17.8% of the basic germplasm accessions were positive for the Bru1 gene, and a low correlation between Bru1 diagnostic markers and brown rust severity was observed for basic germplasm accessions. Overall, Bru1 diagnostic markers proved to be efficient identifying resistant cultivars and clones and have potential to be in screening brown rust resistance in Brazilian breeding programmes.

“…Following the criteria, the sugarcane clones are screened for orange rust resistance following leaf whorl inoculation technique under field conditions (Sood et al 2009(Sood et al , 2013. In China, Wang et al (2013) screened the germplasm after spraying the field with uredospores suspension and observed for symptoms after 4-5 weeks using 0-9 scale. Under All India Coordinated Research project on sugarcane detailed experiments were conducted at Padegaon, Pune, Sankeswar and Anakapalle to standardize a methodology to screen zonal varieties for rust resistance.…”

Sugarcane (Saccharum officinarum L.) is grown in both tropical as well as sub tropical regions and the diseases are one among the major constraints in crop production. The severity of the diseases are mainly influenced by the varieties, crop stage and major weather parameters such as temperature and precipitation. Apart from stalk pathogens such as red rot, wilt and smut, the foliar pathogens of sugarcane especially rust causes substantial yield losses due to disease epidemics in susceptible varieties. The disease has been reported in most of the sugarcane growing countries especially in tropical regions. The uredospores of rust are carried away in wind current and are capable of causing fresh infection in sugarcane plants across the fields. In India, the rust severity is restricted to peninsular regions in Tamil Nadu, Karnataka, Andhra Pradesh, Telangana, Gujarat and Maharashtra and sub tropical states are relatively free from rust diseases due to unfavourable climate for rust pathogens. Though the disease has been reported more than 100 years ago in India, information on sugarcane rust is scanty hence an attempt has been made to review sugarcane rusts and their epiphytotics in the past and their impact on country's economy and importance of rust resistant varieties in containing the disease. Major emphasis was given on the pathogen biology, variability and development of new races in sugarcane growing regions, influence of weather factors in host pathogen interaction and breakdown of resistant varieties, trans-oceanic movement of uredospores, sources of rust resistance among world sugarcane germplasm and Bru genes and their contribution in brown rust resistance and management of sugarcane rusts using chemicals and host resistance.
