Study of different varieties of Jackfruit (Artocarpus heterophyllus) for morphological characterization under Prayagraj agro-climatic condition

Aim: Study of different varieties of Jackfruit (Artocarpus heterophyllus) for morphological characterization under Prayagraj agro-climatic condition. Study design: Randomized block design (RBD) Place and duration of study: Horticulture Research Field, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences (SHUATS), Prayagraj, Uttar Pradesh, India during 2024-25 Methodology: The experiment constitutes of 20 different varieties viz., V1: Janagere, V2: Vietnam SE, V3: Nagachandra, V4: G11, V5: Prashanthi, V6: Sampoorna, V7: Singapore, V8: Rudrakshi Red, V9: Mankala Red, V10: Varashree Y, V11: Thailand New, V12: Ramchandra, V13: Red moon, V14: Honey Jack, V15: Kini Singapore, V16: Shankara, V17: Nagadaka, V18: Wild Jack, V19: Harishchandra, and V20: Gumless. Results: Among the varieties, maximum height(117.67cm), leaf area (72.80 cm), leaf width (70.40 cm) and chlorophyll content (65.33) was recorded in Nagachandra and maximum leaves (1055.33), branches (103), buds (119.66), stem girth(10.4mm) and survival percentage (98%) was recorded in Harishchandra. It is be concluded that variety Harishchandra was found to be most suitable variety followed by var. Nagachandra with respect to percentage increase in number of buds and survival percentage.
