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.
In the present investigation, phenotypic evaluation of blast disease reaction was conducted at Ponnampet and Mandya districts of Karnataka, India, which indicated that the rice varieties such as IR64, Jaya, KMP153, IR30864, Mandya Sona-1, Mandya Sona-2, KCP-1, Dodda Byra, and Malgudi Sanna were susceptible to both leaf and neck blasts. Further, the rice varieties that were resistant to leaf blast such as KMP200, DHMAS70Q164-1b, Karibatta, Coimbatore Sanna and others showed susceptible reaction to neck blast only. In contrast, the varieties such as JyothixBR2655, Punkutt Kodi, Sirsi, 222 and Gangadale which were resistant to neck blast were found to be susceptible to leaf blast also.
