Abstract
This study, conducted at the Experimental Farm of the Indian Institute of Horticultural Research in Bangalore, India, from 2020 to 2023, evaluated phenotypic diversity among progenies from the cross between 'Arka Sahan' and 'Balanagar.' Significant variability was observed in leaf, fruit, and tree characteristics, highlighting the potential for breeding improved Annona cultivars. Growth habits varied, with most progenies exhibiting a columnar or erect form, and a smaller subset showing a spreading growth habit. Leaf characteristics, including length, width, and petiole length, showed considerable variation, aligning with previous research findings. Fruit traits such as weight, length, width, peel, pulp, and seed weight also displayed substantial variation. Few Progenies consistently recorded the highest values for several traits, marking it as a prime candidate for further development. The study underscores the importance of phenotypic diversity for breeding superior Annona varieties, contributing to advancements in pomology and horticulture.
