Biochemical and morphological characteristics of avocado genotypes in Kerala (original) (raw)

In India, avocado cultivation is limited and scattered in the southern and northeastern region of India. A large number of avocado genotypes were available in Kerala, which vary widely in terms of biochemical as well as morphological attributes. In the present study, about 27 accessions (Acc.) were collected from different parts of Kerala, including high-altitude areas and plains. Wide variability in biochemical and morphological traits was observed among accessions collected from different locations. Acc. 11 had the highest vitamin C and Acc. 15 had the highest protein content. The highest fat content was reported in Acc. 7, while the highest oleic acid was recorded in Acc. 10. Acc. 25 reported the highest flavonoid and calcium content. Genotypes collected from Wayanad recorded comparatively higher values for vitamin C, phenols, potassium and crude fibre content. Protein, total fat and calcium contents were comparatively higher in genotypes collected from Idukki. Accessions 7, 10, 11, 12, 14, 15 and 25 could be selected for future conservation, popularization and commercial cultivation based on their biochemical and morphological quality attributes.
