A study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar for determining the ability of various seed vigour parameters to predict the field emergence of 34 varieties of wheat. Twelve seed vigour parameters were evaluated viz. test weight, standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, field emergence index and seedling establishment. The regression analysis was done with respect to standard germination and seedling establishment. Results revealed that the estimated mean of seedling establishment obtained by various viability and vigour parameters viz. standard germination, vigour index-II, accelerated ageing, dehydrogenase activity test, tetrazolium test and vigour index-I were at par with the mean value obtained by observed seedling establishment in the field. The maximum value of R2 was obtained for standard germination, indicating the reliability of this test, followed by tetrazolium test, accelerated ageing test, dehydrogenase activity test, vigour index-I and vigour index-II. The study indicated the reliability of these tests to predict the field emergence in wheat.
