Article Synopsis
- Black root rot (BRR), caused by the fungus Lasiodiplodia theobromae, poses significant economic threats to mulberry farmers in India and China, highlighting the need for effective disease management.
- A study characterized 57 fungal isolates from diseased mulberry roots, revealing variations among 20 isolates and identifying one virulent isolate (MRR-142) through pathogenicity tests.
- The research identified a highly resistant mulberry accession (ME-0168) and eight other resistant accessions, suggesting potential candidates for breeding programs aimed at developing BRR-resistant mulberry varieties.
Article Synopsis
- Mulberry is crucial for sericulture as silkworms feed on its leaves, but there are few genetic options for resistance to root-knot nematodes (RKN).
- A study screened 415 mulberry accessions, identifying 21 as highly resistant and 48 as resistant, with the most resistant found in certain origins.
- Eight accessions were highlighted as valuable genetic sources for breeding RKN-resistant mulberry plants, and molecular analysis confirmed that simple sequence repeat markers can effectively assess genetic diversity between resistant and susceptible mulberry strains.
Aims: Root rot caused by a group of fungi is a serious disease in mulberry. This study aims to identify and characterize Rhizopus oryzae and other fungal species associated with root rot of mulberry in India.
Methods And Results: Rotted root samples were collected from the mulberry gardens from four states of Southern India.
