Abstract

The agronomical indicators of king grass (Pennisetum purpureum) mutants obtained through the application of nuclear techniques (CUBA MF 1000, 12, 18, 24, 30, 40 and 50) and chemical mutagens (CUBA MQ 1 and 2) were studied using a random block design with 4 replications. The greatest height (P<0.01) was attained by CUBA MQ2 (228 cm) during the dry season, while in the rainy season only CUBA MF 12, 24 and 40 were smaller (P<0.05) than king grass. In the dry season none of the mutants differed from the control in density and in the rainy season only the CUBA MF 40 (53.95 kg/ha/cm) was smaller (P<0.05). Four of the mutants surpassed the control (P<0.01) in leaf dry matter percentage with valuesof 26.54 and 27.38% during the dry season, while for stem and the whole plant, differences were less marked. The weight of 10 plants differed with a range of values between 1.70 to 3.20 and between 4.07 to 6.70 kg for the mutants in the dry and rainy seasons, respectively, compared to 1.55 and 5.70 kg for king grass in the same seasons. There weredifferences (P<0.001) in blooming percentage with values between 0 to90% for the mutants (95% For the control). CUBA MF 1000, 12, 18, 24, CUBA MQ 1 and 2 were promisory, although further studies on quality and management are necessary.
