Abstract

Present study was conducted on four genotypes of quinoa to find out optimum temperature and method for germination test at Department of Seed Science & Technology, CCS HAU, Hisar during 2019-20. The result of this study revealed that at 25oC temperature average germination was 22.47 per cent while it was 13.31 per cent at 20oC temperature. Similarly seedling lengths were 9.69 & 7.58cm and seedling vigour index-I were 229.54 & 103.07 at 20 & 25oC respectively. Between the methods, Top of Paper (TP) recorded 19.78 % germination while Between Paper (BP) recorded 16.00 % germination. Similarly, 8.51 & 8.77cm seedling lengths and 157.83 & 174.78 vigour index-I were observed in Top of Paper and Between Paper methods respectively. Poor germination was recorded in all four genotypes (Maximum 42%) which was confirmed by conducting tetrazolium test. It is concluded from the study that 25 oC temperature and both Top of Paper and Between Paper methods can be used for germination test in quinoa crop.  For radical emergence test, 250C temperature for 60 hours should be used and for seed viability test, the seeds should soaked into 1.0% percent tetrazolium solution (2, 3, 5-triphenyl tetrazolium chloride) for 20 hours at 30oC.
