Correlation of seed vigour with field emergence in lentil varieties (Lens culinaris)

Abstract

The investigation was carried out at the laboratory of Department of Seed Science & Technology CSAUA & T Kanpur in 2018-19. Seeds of five lentil varieties viz., KLS 9-3, KLS 320, KLB 345, KLB 303 and KLB 8-4 were investigated for vigour parameters as test weight, Tetrazolium test, seed germination and brick gravel test and these vigour parameters were correlated with field emergence and found that seed vigour was significantly differed among varieties for all parameters, and significantly superior value viz. Tz-test (45.50%), seed germination (97.00%), seedling length (25.53 cm), SVI-I (2476.74), SVI-II (8.57) were found in variety KLB 303 while maximum seedling dry weight (0.089 g) and test weight (26.41 g) were found in Variety KLB 8-4 and maximum brick gravel test (36.00%) was found in variety KLS 320. All vigour parameters were positively correlated with field emergence except test weight.
