NA-6

NA-6 (Narendra Aonla-6) is an amla variety released by Narendra Deva University of Agriculture and Technology (NDUAT), Faizabad, selected from Chakaiya — one of the oldest traditional amla types. Its fruit is medium-to-large, attractive and shining, averaging around 39 g each, and is notable for having the lowest fibre content among the widely-grown named amla varieties evaluated alongside it (NA-7, NA-10, Krishna, Kanchan and Chakaiya itself) in ICAR-CISH studies. This low fibre and attractive appearance make NA-6 particularly well suited to candy and preserve making, where a smoother-textured fruit is valued. It is a heavy, regular bearer once established as a grafted tree, fruiting from about two to three years after planting.
