Leucaena spp., evaluation of genotypes, biological characterizationAbstract
To test promising genotypes of Leucaena spp., selected in a breeding program, an experiment was conducted in a distrofic Red-Yellow Latossol, at the experimental station of EMBRAPA/CPPSE, São Carlos,SP, located at 22°01' and 47°53'W, altitude of 856 m and with a mean annual precipitation of 1502 mm. The following genotypes were tested: L.leucocephala cv. Texas 1074 (T1), L.leucocephala 29 A9 (T2), L.leucocephala 11 x L.diversifolia 25 (T3), L.leucocephala 11 x L.diversifolia 26 (T4), L.leucocephala 24-19/2-39 x L.diversifolia 26 (T5) and L.leucocephala cv. Cunningham (control). Evaluations were performed during the establishment period (fifteen months) and it was concluded that: a) the plants of L.leucocephala 24-19/2-39 x L.diversifolia 26, with early flowering, were the most branched and presented the greatest seed yield; b) the plants of L.leucocephala 11 x L.diversifolia 26, showed the greatest edible dry matter yield; c) the genotypes presented similar or worse growth, than the control, after each harvest.Downloads
