Molecular Identification and Resistance Evaluation to Smut and Mosaic Disease with BC1 of Saccharum×Erianthus arundinaceus

Abstract:

In order to understand the utilization value of hybrids between Saccharum and Erianthus arundinaceus as resistant parents, the resistance to smut and SCMV of some progenies BC₁ from Saccharum×E. arundinaceus were evaluated by artificial inoculation of pathogens. The results showed that most of BC₁ had the resistance to SCMV, and the resistance to smut was segregative among progenies. The BC₁ clones YCE01-48, YCE01-71, YCE01-105, YCE01-125, YCE02-184 and YCE01-118 showed co-resistance to smut and SCMV. So, they could be used as parents with high disease resistance for sugarcane breeding.
