In Vivo Leaf Inoculation: 줄기 구내염의 포플러 육종에서 하이브리드 클론의 질병 저항성을 평가하는 대체 방법

Executive Industry Relevance

Rapid, quantitative assessment of disease resistance in poplar hybrids addresses a critical bottleneck in forestry biotechnology pipelines. The in vivo leaf inoculation method enables high-throughput, early-stage screening, accelerating the identification and triage of resistant clones for stem canker pathogens. This approach enhances predictive confidence and portfolio advancement in disease-resistance breeding programs.

Strategic Applications in Biopharma R&D
