Genotypic variability studies and identification of pre-harvest sprouting tolerant wild Vigna

Seed dormancy is the main component of domesticated traits, loss which results into rapid and uniform germination, synchronous maturity ease in harvesting. However, breakdown or fresh seed (FSD) has made seeds vulnerable to pre-harvest sprouting (PHS). Though, Vigna species are protected by pod, these still susceptible PHS. Identification donor(s) having short duration FSD (30-45 days) become utmost important transfer trait high yielding varieties. The wild progenitors relatives cultivated offer a source several useful traits; therefore, experiment was initiated understand level variation PHS germination (FSG) accessions species. FSG among 59 ranged between 0-100%, with mean 55.86% 61.19%, respectively. Five (IC276983, IC349701, Trichy Local 1, LRM/13-33 LRM/13-26) trilobata one accession (IC251440) sublobata recorded no pod due 0% (2.5% V. sublobata). size showed positive association PHS, where smaller (100-SW <1 g) comparably low (30.82%) than bold (69.06 62.94% 100-SW 1-2 g > 2 g, respectively). identified, especially (crossing compatible) could be used as tolerance species, particularly mungbean urdbean.
