The quality seed production in rice is ensured by different classes of seed involving Nucleus, Breeder, Foundation and Certified seed at different cropping stages attributing seed requirement of farmers at diversified and sustainable crop production of rice. In this regard, the maintenance breeding attributed as a foremost factor for wider spread of a particular rice variety. The chance of outcrossing and genetic drift were removed through sustained maintenance breeding to maintain the seed purity and thereby contributing to 30 to 40 per cent higher crop production. The present study involves the interpretation of relative performance of rice varieties ASD 16 and TPS 5 considering the breeder seed indent and area spread by the concerned variety. Over years of 2016-17 to 2020-21, the breeder seed indent of ASD 16 pronounced as 3604kg and the projected area was estimated to be 5.06 m.ha. Further, the average indent of rice TPS 5 remains at 260kg with projected area of around 0.36m.ha. Although the yield potential of rice TPS 5 is significantly higher, the adoption remains significantly lower. The factors promoting the greater adoption of ASD 16 were studied and it was adjudged that good market price of ASD 16 grain, lack of awareness of TPS 5 rice variety, lack of awareness about the grain and cooking quality attributes of TPS 5 in comparison with ASD 16 rice variety. Moreover, the greater preference of ASD 16 rice variety for nearly three decades had contributed for enhanced adoption of ASD 16 and poor adoption of TPS 5.
