Identification of Twenty-One Brassica Genotypes through Physiological Parameters

Nation Chamling ^[2] | P. G. Devhade

Abstract: Average germination potential of harvest fresh seeds was recorded to be maximum i. e. , 98 % for Agrani, Saroma, SP-2, SP-5 and SP-6 irrespective of the years of experimentation; in addition to those exactly similar performance (98 % germination) was noted for Multi Locular only in 2012-13, and for Benoy, Rajendra Sarson, Samrat and SP-1 in 2013-14. Speed of germination of seed was also exhibited as maximum by Saroma in both the years followed by similarly performing Rajendra Sarson and Panchali produced in 2013-14, while Saroma was followed by Panchali, SP-6, Sanjukta and Rajendra Sarson, in 2012-13 having non-significant differences amongst itselves. Seeds of SP-1, SP-3 and SP-5 also exhibited higher speed of germination in both the years. Variation in both seedling fresh and dry weight was found to be significant amongst the genotypes considered under this programme. Maximum magnitude of vigour index was determined for the genotype Rajendra Sarson in both the years being significantly best performer than the other genotypes except Samrat in 2013-14 only. It was followed by Tori Local, Sanjukta and Samrat in first year and by Jumka, Tori Local, Sanjukta and NRCYS in second year, the laters performed significantly in similar manner in both the year. While the seeds of Multi Locular were of lower vigour status preceded by SP-7 in both the years, though non-significant difference in this parameters was noticed between these two genotypes in 2013-14.
