Abstract

Mutants of king grass (Pennisetum purpureum sp) obtained by nuclear techniques (CUBA MF 1000, 12,18,24,30,40 and 50) and chemical mutagens (CUBA MQ 1 and 2) were studied in a random block design with 4 replications. Peroxidases and esterases showed a marked enzymatic polymorfismand differences in number, position and intensity of the bands were found. 20 days after sowning, germination of CUBA MF 12 and CUBA MQ 1 excelled the control, while at 50 days, except for CUBA MF 18 and 30, the values were higher (P < 0.001) than the control. Plant height at 20days was superior (P < 0.001) in CUBA MF 1000, 12, CUBA MQ 1 and 2 and only CUBA MF 1000 excelled (P < 0.001) king grass at 50 days, however at 90 days no differences were found with the control treatment. Thelowest growth (P < 0.05) was for CUBA MF 30 and varied from 1.16 to 2.05 cm/day. CUBA MF 50 showed the lowest number of sprouts (3.14) at 90 days (P < 0.05) while at 20 and 50 days no differences were encountered. CUBA MF 30 showed a more delayed establishment while CUBA MF 1000, 12 and CUBA MQ 1 were promisory plants during establishment.
