Accelerated Aging Studies of Normal and Segregating Chlorophyl Deficient Isolines of Pearl Millet¹

Pearl millet (Pennisetum americanum (L.) Leeke) seeds were subjected to accelerated aging for various periods at temperatures of 21 and 32 C and relative humidities (RH) of 70 and 90%. Seeds stored at 32 C-90% RH rapidly lost germination capacity, while seeds stored at 21 C-70% RH lost viability more slowly. Seedlings apparently passed through an abnormal stage before dying. Isogenic lines heterozygous for six different chlorophyl deficiency genes were allowed to self-pollinate and the resulting seeds were tested to determine the effects of rapid aging on the ratio of normal to chlorophyl deficient seedlings. No differences in the genetic ratio were observed following accelerated aging.
