ABSTRACT: Study was conducted to compare fresh, natural and accelerated seed lots of wheat with germination and vigor index varied from 98.67 to 44.00 and 2960 to 524.92 respectively. Germination loss became more in accelerated ageing as compared to fresh and natural aged lot. Total soluble seed protein banding pattern of different aged seed revealed that there has been decline in band intensity, band numbers or disappearance of some bands with ageing; it is more in accelerated aged lot as compared to natural aged seed lot. Thus, seed lot with slight variation either in germination or vigor in germination or vigor could also be used for varietal characterization by SDS-PAGE to differentiate the cultivars or even for genetic purity testing, but not the seed lots which are severely aged that lost threshold limit of 50 per cent.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This research examines the impact of both accelerated and natural aging on the total soluble seed protein profile of wheat (Triticum aestivum). It aims to determine a threshold limit for seed aging, up to which seeds can be used for electrophoretic analysis to differentiate cultivars and assess genetic purity. The study investigates the effects of aging on germination, vigor index, and protein banding patterns in different wheat varieties.

Schlüsselwörter (Keywords)
The study primarily focuses on wheat seed ageing, seed protein profiles, electrophoresis, SDS-PAGE, and varietal characterization. The research explores the use of protein profiles as a tool for distinguishing wheat cultivars and assessing genetic purity in relation to seed ageing. The research aims to establish a threshold limit for seed aging, allowing for accurate and reliable varietal characterization and genetic purity testing.
