Qualitative and quantitative characterization of jackfruit (Artocarpus heterophyllus Lam.) genotypes for yield and biotic stresses

Abstract

The present experiment entitled “Qualitative and Quantitative characterization of jackfruit (Artocarpus heterophyllus Lam.) genotypes for yield and biotic stresses was carried out at the Dr. YSRHU-Horticultural Research station, Venkataramannagudem, Andhra Pradesh during the year 2023-2024. Results recorded that maximum leaf blade length was recorded in Acc-7 (15.93 cm), while leaf blade width in Acc-17 (11.73 cm). Further fruit weight was maximum in the genotype Acc-18 (15.13 kg), fruit length was recorded in the genotype Acc-18 (51.80 cm) and yield per tree in the genotype Acc-15 (631.3 kg). Percent incidence of fruit rot (20.13%), rhizopus fruit rot/male flower bud (19.34%) was maximum in the genotype Acc-15 and maximum severity of leaf spot (4.13%) was recorded in the genotype Acc-12. The maximum mean incidence of fruit borer (10.44%) and shoot borer (10.43%) was observed in the genotype Acc-15.
