Description In the context of seed storage, 6 accessions from the ICRISAT germplasm collection, 4 of which had pea-shaped seeds, were studied to investigate the effect of drying on seed splitting (cleavage). Drying in a cabinet at 15 +- 1 deg C and 15 +- 2% relative humidity (RH) caused much more damage than drying over silica gel at 15 deg C, but the latter method took much longer. Almost all pea-shaped seeds were damaged in the cabinet compared with only 28% and 12%, respectively, of seeds from varieties with semispherical or owl-head-shaped seeds. On the basis of preliminary results a 2-stage drying procedure is recommended: (1) initial slow drying in a cabinet at 15 deg C and 30-40% RH until moisture content reaches 9% or less, followed by (2) drying at 15 deg C and 15% RH to reduce moisture content to the 7% required for long-term storage., 5 ref., In the context of seed storage, 6 accessions from the ICRISAT germplasm collection, 4 of which had pea-shaped seeds, were studied to investigate the effect of drying on seed splitting (cleavage).
