Abstract:
The present variability studies for morphological characters in acid lime (Citrus aurantifolia Swingle) were laid out at out at the All India Coordinated Research Project on Fruits, Dr. Y.S.R. Horticultural University, Citrus Research Station, Tirupati during 2020-21 and 2021-22. The experiment was conducted in Randomized Block Design (RBD) with three replications comprising forty genotypes. Significant variation among the genotypes for characters studied like tree shape, tree growth habit, leaf lamina shape, leaf apex, number of stamens, seed shape and seed colour. No variation was noticed for the qualitative characters viz., shoot tip colour, leaf lamina attachment, leaf lamina margin, petiole wings, Flower colour, type of flower and anther colour. Variation was noticed for characters like plant height, canopy spread, canopy volume, leaf lamina length, leaf lamina width, petiole wing length, pedicel length, petal length, petal width, spine density, spine length, highest plant height was recorded in selection-16. PKM-1 was recorded with highest canopy spread in the east-west direction, highest canopy volume, highest pedicel length and highest petal width. TAL/94-14 recorded highest canopy spread in the north-south direction compared to other genotypes. The variation studied in the genotypes may be helpful in selection of genotypes for incorporation of desirable characters to offspring.
