Abstract:
The present investigation entitled “Screening of Turmeric genotypes against shoot borer, Conogethes punctiferalis” was carried out at Instructional farm, Department of Vegeteble Science, Dr. PDKV, Akola during 2020-21. A field experiment was carried out to find out the promising genotype against shoot borer i. e. Conogethes punctiferalis. A set of 24 genotypes used for experiment viz. PWTM-1, PWTM-3, PWTM-4, PWTM-5, PWTM-6, PWTM-8, PWTM-9, PWTM-10, PWTM-11, PWTM-14, PWTM-19, AKTL-3, AKTL-8, AKTL-10, AKTL-11, AKTL-12, AKTL-13, AKTL-16, AKTL-18, AKTL-19, PDKV Waigaon, PTS-10, Salem, Pragati were obtained from Department of Vegetable Science, Dr. PDKV, Akola during 2020-21. The results revealed that out of 24 genotypes evaluated the minimum per cent of infestation was noticed in three genotypes, i. e. PWTM-9 (0.9%), AKTL-12 (2.3%), AKTL-11 (3.2%). Overall mean per cent of shoot infestation recorded was varied from 0.9 per cent in PWTM-14 to 15.8 per cent in PWTM-9. Among the 24 genotypes Twenty-one genotypes registered 0.10- 12.50 per cent shoot infestation was graded as moderately resistant and remaining three genotypes showed 12.60- 17.10 per cent shoot infestation were placed under moderately susceptible category. None of the genotype were found highly resistant, susceptible and highly susceptible. In the correlation study of weather parameters with infestation of Turmeric shoot borer no significant correlation was observed with any weather parameters. Correlation study of mean infestation with morphological characters i.e. plant height, number of tillers and yield showed no significant correlation whereas leaf lamina showed negatively significant correlation.
