Abstract

Sixteen low temperature stress tolerant groundnut genotypes were evaluated for the levels of crude fat, crude protein, reducing sugar, non-reducing sugar and total sugars from the defatted meals. Out of 16 genotypes, four genotypes viz., NRCG 1613, NRCG 9799, NRCG 12212 and NRCG 2510, germinated at 15°C, and the contents of proline and extracted soluble proteins from leaf material were resolved on a denaturing polyacrylamide gel in order to observe the differences, if any, in banding patterns under stressed condition. The seeds of low temperature stress tolerant genotype ICG 6888 demonstrated the highest fat content of 52.46%, followed by 49% in NRCG 9799. Among the 16 genotypes, ICG 1298 and ICG 6570 recorded the highest crude protein content of 38.5% in their defatted meals followed by 37.62% in ICG 7005. The reducing sugar content in defatted groundnut seeds was also recorded and the genotype ICG 1256 showed the highest reducing sugar content of 1.60%, followed by 1.40% in ICG 3942. The highest total sugar content was recorded in ICG 1298 with 9% followed by 8.10% in ICG 1256.
