NOVELTY - An intra specific hybrid of J. curcas plant designated as Nandan-1 produced by crossing JCZ-P34 and JCZ-I84 and applying biparental crossing process adopting North Carolina Design at F2 generation following selection, is new.    USE - The intra specific hybrid Nandan-1 plant or plant part is useful for producing a biofuel, where the biofuel is biodiesel (all claimed). The plant is further is useful for developing further Nandan-1 plant lines and hybrids with desired traits, e.g. resistance to disease and insect pests, improved canopy structure, tolerance to environmental stresses, improved agronomic characteristics and/or higher seed yield.    ADVANTAGE - The present invention provides new and distinctive J. curcas hybrid designated as Nandan-1 for high seed yield and construction of molecular marker specific to hybrid Nandan-1. It provides new, unique and superior J. curcas hybrids. It provides stable, high yielding hybrid that are agronomically sound.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are: (1) a J. curcas hybrid plant (Nandan-1) or a plant part, produced by asexual propagation or tissue culture process or growing the seed above; (2) pollen of the hybrid plant (Nandan-1) of (1); (3) an ovule of the hybrid plant (Nandan-1) of (1); (4) a J. curcas hybrid (Nandan-1) plant or a plant part, is having all of the physiological and morphological characteristics of the J. curcas hybrid (Nandan-1) plant of (1); (5) a tissue culture cellls produced from the J. curcas hybrid (Nandan-1) plant of (1), where the cellls of the tissue culture are produced from a plant part selected from leaves, pollen, embryos, cotyledons, hypocotyls, meristematic cellls, roots, root tips, pistils, anthers, flowers, inflorescence, and stems; (6) a protoplast produced from the hybrid (Nandan-1) plant of (1); (7) a J. curcas hybrid (Nandan-1) plant regenerated from the tissue culture of (5), here the plant has all the morphological and physiological characteristics of hybrid Nandan-1; (8) a process of producing the J. curcas intra specific hybrid Nandan-1; (9) a method of producing pollen from an intra specific hybrid of J. curcas plant designated as Nandan-1 by forming the plant by the method of (8) and extracting pollen from it; (10) a method of producing an ovule from an intra specific hybrid of J. curcas plant designated as Nandan-1 by forming the plant by the method of (8) and extracting an ovule from it; (11) a method of producing a protoplast from an intra specific hybrid of J. curcas plant designated as Nandan-1 by forming the plant by the method of (8) and extracting a protoplast from it; (12) a method of producing a microbiological product from an intra specific hybrid of J. curcas plant designated as Nandan-1 by forming the plant by the method of (8) and extracting a microbiological product selected from either a pollen celll or an ovule celll or one or more of embryos, protoplasts, meristematic cellls, callus, leaves, anthers, pistils, root tips, seeds or stems; (13) a method of culturing tissue cellls from an intra specific hybrid of J. curcas plant by culturing tissue cellls produced from the J. curcas plant, where cellls are selected from leaves, pollen, embryos, cotyledons, hypocotyls, meristematic cellls, roots, root tips, pistils, anthers, flowers, inflorescence, callus, seeds and stems; and (14) a biofuel generated by the use of the intra specific hybrid Nandan-1 plant or plant part.
