Abstract:
An experiment entitled “Varietal reaction of tamarind (Tamarindus indica L.) Against fruit borer” was conducted at the Horticulture Nursery Farm, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist.-Ahmednagar (Maharashtra) during season 2021-22. Nineteen genotypes viz., RHRTG-1, RHRTG-2, RHRTG-3, RHRTG-4, RHRTG-5, RHRTG-6, RHRTG-7, RHRTG-8, RHRTG-9, RHRTG-10, RHRTG-11, RHRTG-12, RHRTG-13, RHRTG-14, RHRTG-15, RHRTG-16, RHRTG-17, RHRTG-18 and RHRTG-19, were evaluated in Randomized Block Design (RBD) with two replications. Among these samples collected from fruiting genotypes RHRTG-1, RHRTG-2, RHRTG-4, RHRTG-6, RHRTG-9, RHRTG-14 were evaluated for morphological and for biochemical characteristics of tamarind to study performance against fruit borer resistance. Study of various morphological characteristics revealed that, genotype RHRTG-6 which had minimum curvature length and low content of fibre showed moderate resistance to fruit borer while genotype RHRTG-14 wastolerate recorded maximum curvature length and high content of fibre followed by RHRTG-9. Among all the genotypes, RHRTG-6 which had low content of sugar and high content of tannin, ascorbic acid, and phenol showed moderate resistance to fruit borer. Tolerate genotype was RHRTG-14 followed by RHRTG-9 which had higher content of sugar and lower content of tannin, ascorbic acid, and phenol.
