Abstract:
The present study entitled “Assess the effect of natural ageing on seed quality of Wheat seed (Triticum aestivum L.)” was conducted during rabi 2018 -2019 at Department of Seed Science and Technology and Oil Seed Farm of CSAUA&T, Kanpur in Seed Testing Laboratory. The freshly stored seed was observed highest seed quality parameters i.e., germination percent, seedling length, seedling dry weight and seed vigour indices as compared to seeds that were stored for 6 months. In both the variety highest standard germination was observed in WH-1105 (70.61%) while lowest was observed in WH-1124 (69.93%). The longest seedling length was observed in WH -1105 (16.85 cm) while shortest was observed in WH -1124 (16.09 cm). In both the variety maximum vigour Index- I was observed in WH-1105 (1500.45) while minimum was observed in WH-1124 (1425.74). The maximum vigour index-II was observed in WH- 1105 (11.52) while minimum was observed in WH -1124 (10.56). Based on the results, WH-1105 was found as superior variety in majority of the viability and vigour constraints results whereas WH - 1124 variety was recorded inferior. Among the storage periods the physiological parameters maximum was record ed. in the month of July and minimum in month of December. Conclusion found that comparing the result obtained in the months of July WH -1105 recorded better performance and WH-1124 recorded moderate and poor performance in maximum vigour test in wheat.
