Abstract
The laboratory analysis was carried out to assess seed quality parameters at Department of Seed Science and Technology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (U.P.) India. The study revealed that, among the sowing dates significant differences were observed. The study was conducted to examine the effect of high temperature on seed quality attributes were better in respect of 24th November sowing followed by 15th October and 20th December sowing. The variety HI-1544 produced higher seed yield than others, while GW-273 recorded less but stable performance during early as well as late sown conditions. Seed quality parameters viz., thousand seed weight (g), seed density (g cc-1), germination (%), vigour index, seedling dry weight (g), seed reserve utilization efficiency (g g-1) were better in the sowing of 24th November. However, electrical conductivity was lower in 24th November sowing. The variety GW-322 followed by HI-1544 had better quality than the rest varieties.
