Description Not Available
In the present study, a field and in vitro screening approaches were followed to identify the resistant Musa accessions (n=310) against banana corm weevil Cosmopolites sordidus (Germar). The corm was crosssectioned and the tunnels (galleries) made by the grub were recorded. Based on the ratio of galleries, the % was calculated. The infestation level was categorized into resistant, less, moderate and highly susceptible. The results revealed three resistant accessions viz., Kanthali (ABB- Pisang awak), Sambalneyvannan (ABB- Pisang awak) and Bhimkol (BB- wild balbisiana). Around 44 accessions (AA:2, AAA:5, AAB:9, AB:4; BB:5; ABB:15, ABBB:2; Rhodochlayms:2) from different genomes were identified as less susceptible.
