Increases in rice grain yield depend on introduction of potential cultivars including hybrids into Andaman and Nicobar islands that with small acreage (5340 ha) won’t merit developing hybrids locally. The objective of this study was to evaluate newly released hybrids and high yielding varieties of rice elsewhere in the country and identify promising ones for augmenting the huge production shortages in the islands. Twenty rice cultivars (17 hybrids and 3 high yielding varieties) were field evaluated using randomised complete block design with two replicates at Port Blair, Andaman & Nicobar Islands during kharif season of 2017. Results revealed that five hybrids (28P09, NK-16520, 27P36, KPH-272 and PAN-2423) and two varieties (NDR-359 and Gontra Bidhan-3) have 14-26% higher grain yields than local check variety ‘CARI Dhan-6’ (3.1 t/ha). Based on 10 and 20% increase in yield as criteria for release of a variety and hybrid in the country, NDR-359 (21%) and Gontra Bidhan-3 (23%) varieties and 28P09 hybrid (26%) merits are introduction. From economics point of view, Gontra Bidhan-3 (250%) followed by NDR-359 (217%) and 28P09 hybrid (214%) with 227% higher net income than local check (Rs. 9121) proved their merit. This study provided evidence to suggest that new cultivars introduction could augment the rice production shortages in the islands to some extent.
