Evaluation of BC1 and BC2 from the crossing Erianthus arundinaceus with Saccharum for resistance to sugarcane smut caused by Sporisorium scitamineum

Abstract

Sugarcane smut disease caused by the fungus Sporisorium scitamineum is one of the important fungal diseases affecting sugarcane yield and sucrose content around the world. Cultivar resistance is the most appropriate control method for this disease. In this study, 37 BC 1 lines chosen from the crossing YC96-40 (F 1 of Erianthus arundinaceus) × CP84-1198 (commercial sugarcane cultivar) and 42 BC 2 lines chosen from the crossing YCE01-116 (BC 1 of E. arundinaceus) × Neijiang57-416 (commercial sugarcane cultivar) were evaluated for smut resistance using artificial inoculation. The results showed that of 79 tested BC 1 and BC 2 lines of E. arundinaceus, 10 (12.7%) were highly to moderately resistant to smut. BC 1 of E. arundinaceus had more resistant lines than BC 2 of E. arundinaceus. Of the 37 tested BC 1 lines of E. arundinaceus, seven (18.9%) were highly to moderately resistant, while three (7.1%) of the 42 tested BC 2 lines of E. arundinaceus were highly to moderately resistant to smut. The resistant lines identified in this study could be used as sources of smut resistance in sugarcane breeding programs.

Whole Genome Analysis of Sugarcane Root-Associated Endophyte Pseudomonas aeruginosa B18—A Plant Growth-Promoting Bacterium With Antagonistic Potential Against Sporisorium scitamineum

“…It is wide-spread in all the major sugarcane production areas in China, such as Guangxi, Yunnan, Guangdong, and Hainan. Sugarcane smut disease control currently relies primarily on breeding resistant cultivars (Shen et al, 2014), which is constrained by long, expensive breeding procedures and limited success (Liu et al, 2017). The disease can be managed by chemical fungicides (Bhuiyan et al, 2012) but is neither advised nor practiced to prevent environmental degradation (Pandin et al, 2017).…”

Physiological Mechanisms of Improved Smut Resistance in Sugarcane Through Application of Silicon

“…In the past 20 years, smut has become one of the most economically harmful sugarcane diseases in mainland China. Currently, the main sugarcane cultivars in China are infected with smut, and the incidence in the field ranges from 10% to 20%, severely affecting yield and quality ( Que et al, 2012 , 2014 ; Shen et al, 2014a ). The mycelium of S. scitamineum infects sugarcane buds and spreads through intercellular hyphae to the rest of the cane.…”

Contribution of sugarcane crop wild relatives in the creation of improved varieties in Mauritius

“…High fibre, vigour and biomass are known major components of hybrids having S. spontaneum as genitors, thereby confirming the interest among breeders in exploiting these wild species (Matsuoka et al ., 2014). Successful hybridization with related genera, mainly Erianthus , is also a major research thrust among contemporary sugarcane scientists (Shen et al ., 2014; Gao et al ., 2015). Other studies in more temperate countries involve the creation of ‘Miscanes’ between sugarcane and Miscanthus species (Jessup, 2009; Głowacka et al ., 2016) to develop frost resistant energy canes.…”
