1. In this report we recognize 29 races of maize, of which six are "poorly defined". This classification is based on 675 collections, which were studied with respect to ear characteristics and geographical distribution. A provisional arrangement made on this basis was revised by study of plant, tassel, and other characteristics. 2. General descriptions, tabular data on ears, tassels and other characters, internode diagrams, ear cross-sectional diagrams, and ear photographs and distribution maps ar presented for each race. 3. The great diversity of Ecuadorian maize is related to the complex geography and history of that country. Races have been introduced from the north and south; hybridization between races has occurred; and geographical isolation haspermitted the development of new forms in cental highland Ecuador. 4. Positions of chromosome knobs were determined for 14 of the 29 races described. The Andean knob pattern, first discovered in the races of highland Bolivia, is extended at least to northern Ecuador. Knob patterns are more variable in lowland races, and total knob number is generally higher. |

This study aimed at verifying the efficiency of early selection, and estimating the genetic parameters in Dipteryx alata. The 66 half-sib families were obtained from three seed provenances at the Brazilian Savannah of the state of Minas Gerais. The experiment was carried out in a randomized block design with 3 replications and 5 plants per plot. Data diameters at breast height (DBH) and total height (TH) were taken at the ages of 64, 125 and 138 months. REML/BLUP methodology was applied in the D. alata different provenances and progenies. Analysis indicated significant genetic variability (P < 0.01) between and within provenances. Both traits, DBH and TH, presented high narrow sense heritability for the ages analyzed. High genetic correlation occurred between DBH and TH traits, and between ages (age-age); thus, it allowed indirect selection, as well as early selection with high genetics gains. |
