Abstract

Generally, seed multiplication procedure is followed only for the certification of high yielding, hybrid varieties etc. which are notified under Seed Act 1966. In this regard, we have challenge to protect our traditional varieties of paddy for the development of sustainable agriculture. These varieties' values are very significant because it’s containing significant genes. Traditional rice varieties can be multiplied as seed in order to acquire high-quality seeds while maintaining the quality of their existing features. Therefore, sixty-two (62) traditional rice varieties of West Bengali were collected and stored at a low temperature in a deep freezer at -10 degrees centigrade at the Crop Research and Seed Multiplication Farm, The University of Burdwan. Seeds were multiplied after six months of storage in order to study yield and other important agronomic traits among the varieties. A wide variation of yield and other valuable agronomic traits like plant height (cm), total number of tillers per hill, number of panicles per hill, number of seeds per panicle, number of chaffy seeds per panicle, duration of 50% flowering (days), 100 seed weight (gram), maturity duration (days), length of panicle (cm), length of flag leaf (cm), grain characters like presence or absence of awning were found among the varieties during Kharif season of 2020 and 2021. These traits may be used in future to choose the parents in a breeding programme to develop high yielding, hybrid varieties.

Conclusion

The future food supply depends critically on maintaining traditional paddy varieties. It can be possible when researchers, seed growers and farmers will try to apply the seed multiplication procedures for protecting these traditional varieties. With accordance to the yield and other agronomic characters examined, the current study showed great variance among the traditional varieties of paddy. These variance are helpful for evaluating genetic diversity among the varieties.
