An experiment was conducted during (2002 to 2017) to select regular bearing spongy tissue free half sibs from seedling population of mango cv. Alphonso. Elite Alphonso trees having a history of regular bearing were selected at Agriculture Experimental Station, Navsari Agricultural University, Paria, Gujarat and in adjoining areas at fields of progressive farmers. Mature fruits were collected from these trees, ripened at room temperature and 228 extracted stones were planted at 5x2.5m spacing in 2002. Alternate Bearing Index (ABI) was used to select thirty regular bearing seedlings (ABI < 0.25) on the basis of yield/tree of 148 surviving seedlings during 2012 to 2017. Based on the yield and fruit characteristics of these trees, three selections (25, 29 and 30) had regular bearing tendencies with promising shape of fruit, colour of pulp, taste and other biochemical parameters and were recommended for further evaluation in block plantations. Incidence of spongy tissue was not recorded in the fruits and there was no major incidence of pest and diseases on these selected plants.
