Abstract

The expertise of agro-morphological variability within a crop and its dispersion across agro-ecological areas may be very useful in managing the crop’s germplasm and developing improved methods. Crop failure is guarded against through genetic variety. However, dwindling genetic wealth erodes the capacity to maintain and enhance agricultural productivity. West Bengal has rich rice genetic wealth. But this genetic wealth is being silently depleted due to the onslaught of the high-yielding varieties (HYVs) and neglect The 10 traditional rice varieties were collected from the Cooch Behar district of West Bengal, India. The present study aimed to characterize the rice genotypes using agronomic characters. The assessment was done following the Standard Evaluation System (SES) for rice developed by the International Rice Research Institute. Even though all the ten local rice varieties were adapted to the Cooch Behar district, a fair amount of diversity was found among the rice genotypes.

Highlights

The issue of food security is significantCrops' genetic diversity provides the basis for today in light of climate change
There have been morphological diversity, farmers will have a studies on the genetic diversity analysis more remarkable ability to use the crop's among rice germplasm over the years (Singh germplasm, which will benefit crop et al, 2010, Parikh et al, 2012)
Though all the rice genotypes belonged to Oryza sativa L., the present study revealed sufficient genetic divergence for various agronomic traits (Table 2)

Summary

Introduction

The issue of food security is significant. Crops' genetic diversity provides the basis for today in light of climate change. An insurance policy must guard weather events, population growth, and against crop failure via genetic variety Plant genetic ways to increase food security Once understanding of the crop's agrolost, they are lost forever. There have been morphological diversity, farmers will have a studies on the genetic diversity analysis more remarkable ability to use the crop's among rice germplasm over the years (Singh germplasm, which will benefit crop et al, 2010, Parikh et al, 2012).
