Effect of storage period on different seed viability parameters in rajmash (Phaseolus vulgaris)

Seed longevity mainly depends on initial seed quality and storage conditions therefore; farmers gene bank curators need to be aware of the potential rajmash cultivars that contribute production high during routine germplasm regeneration/multiplication. Consequently, it is important generate information rajmash. In present investigation, 14 yielding were stored for 4 years periodical germination percent, time initiate (t1), achieve 50% (t50) uniformity (U7525; between 25 75 % germination) recorded. The varieties exhibited mean percentage 93, 73, 3 0.9 when 0, 1, 2, years, respectively. results demonstrated that, all could safely a minimum period 1 year at ambient condition. Seven (Arka Komal, IPR 98-5, 98-3-1, HUR 137, 203, HPR 35, Gujarat Rajmash 1) 2 as they more than requirement (75%) Indian Minimum Certification Standard. Storing seeds extended not only decreased final percentage, but also increased t1, t50 t7525, suggesting use aged result into poor field establishment coupled with delayed non-uniform germination.
