Hence, the present study was carried out to understand the morphological and biochemical differences between the CNSL free mutant (NRC-116) and CNSL containing (Bhaskara) genotype. Morphologically, NRC-116 differed from Bhaskara in leaf shape and dimensions, and reproductive characteristics like sex ratio and yield-related traits. The nutshell thickness of NRC-116 was significantly less compared to Bhaskara. Biochemical analysis showed that NRC-116 is absolutely free of CNSL and significantly differed from Bhaskara in kernel FAs, proteins, oils and phenolics.
