Assessment of Seed Quality in Naturally Aged Seed Lots of Fenugreek (Trigonella foenum graecum L.) Germplasm

In the present study, the seed of two seed lots, viz. L1 (fresh harvested seed) and L2 (one year old seed) of each of six genotypes viz., RMT-361, RMT-303, RMT-354, RMT-351, RMT-305 and NRCSS-AM-1 of fenugreek were taken and stored under ambient conditions. All the genotype-lot combinations were studied in the laboratory as well as in the field. All the seed lots of six genotypes were subjected to various vigour tests and observations were recorded on test weight (g), seed density (g/cc), standard germination (%), seedling length (cm), seedling dry weight (mg), vigour index-I, vigour index-II, field emergence index (FEI), mean emergence time (MET, days) and total seedling establishment (SET, %). Considering all the seed vigour parameters, L1 seed lots of all the genotypes were found to be more vigorous than L2 seed lots of respective genotypes. The variety NRCSS-AM-1 was found more vigorous, followed by RMT-305 and RMT-354, whereas RMT-351 was found low vigorous.
