dc.description.abstractA total of eighty mango accessions located in the orchard were mapped using ArcGIS software. However, only seventy-two of these are analyzed by the Shannon-Weaver Diversity Index due to some accessions being cut down or dead. The remaining mango accessions were characterized using the International Plant Genetic Resources Institute's (IPGRI) descriptor list, with a total of seventeen morphological traits, twelve of which are qualitative traits and five of which are quantitative traits. According to the Shannon-Weaver Diversity Index (H'), the general mean of mango characters has a diversity index of 0.73. For qualitative traits, the diversity index was 0.62, while the mean average for quantitative traits was 0.84. The majority of mango accessions had higher diversity in qualitative traits such as leaf texture (H’= 0.99), mature tree height (H’= 0.96), foliage density (H’= 0.81), and leaf fragrance (H’= 0.78). Meanwhile, all quantitative traits, such as trunk circumference (H’= 0.80), crown diameter (H’= 0.87), leaf blade length (H’ = 0.86), leaf blade width (H' =0.88), and petiole length (H’= 0.80), showed greater diversity. This higher level of diversity of mango accessions located in the orchard should be maintained by using the map for easier monitoring, inventory, and access of a breeder or curators, particularly during varietal improvement. © 2024 Association of Agricultural Technology in Southeast Asia.
