Abstract
A study made at the Horticultural Research Station, Pechiparai to evolve a new jack variety with higher per plant yield, firm flesh, regular bearing tendency, adjustable for commercial planting and suitable for all regions of Tamil Nadu from 14 germplasm collection has resulted in the selection of a promising clone PAH 10, released as PPI-1. It is a clonal selection from Kazhukupala type. This high yielding varitey comes to first fruiting in five years. It out yielded the local variety with 107 fruits, weighing 1818 kg compared to the local variety which gave 75.7 fruits weighing 865 kg. The yield increase over already released jack variety PLR.I is 204 per cent for fruit number and 305 per cent for fruit weight in the off season. The firm and attractive carpels with sweet and pleasant aroma are the advantages of this variety. This new variety can be propagated in larger number in a short time through budding method standardised at the station.
