A new jumbo nut hybrid H-130 which was superior in yield (3kg/tree in 3 years of planting) with cluster bearing (10-20 nuts/panicle) and bold size (12-13g nut weight) and big apple (>100g) was evaluated and released for cultivation and performance evaluation in farmers field. The hybrid is highly precocious, early flowering with long fruiting duration. Plant is vigorous but sparse canopy and having large leaves and big inflorescence with strong 8-10 rachis.
