Abstract
The present investigation was carried out at Regional Horticultural Research and Training Station, Dhaulakuan, Sirmour, Himachal Pradesh, India during 2016-17 and 2017-18 with an objective to study the morphological characters of nine guava cultivars and hybrids for proper selection of cultivars for cultivation. The pooled data revealed that maximum tree height (5.57 m), trunk girth (53.27 cm) and tree volume (73.66 m3) was found in Allahabad Safeda. Whereas, the maximum tree spread in North-South (4.7 m) and East-West (5.69 m) direction was observed in CISH-G-4. Among all the cultivars and hybrids, Lalit was found superior in yield characters with maximum fruit weight (171.71 g), yield (16.45 kg tree-1) and minimum yield efficiency (7.43 g cm-2 TCSA). In conclusion, among nine cultivars and hybrids evaluated, Allahabad Safeda and Lalit were found superior in growth and yield characters, respectively.
