Resumen
En Turrialba, se evaluaron 32 genotipos de maní procedentes del ‘International Crops Research Instituto for the Semi-Arid Tropics’ (1CRISAT), para observar su comportamiento y seleccionar los materiales con mayor rendimiento y mejor aspecto de grano. Se utilizó un diseño de bloques completos al azar con cuatro repeticiones. El rendimiento promedio de los 32 genotipos fue de 3523 k de grano/ha; la mayoría de ellos tuvieron entre 40 y 45 cápsulas/planta ; la relación grano/cápsula varió de 70 a 78%. Aunque la variación en rendimiento de grano entre la mayoría de genotipos no fue significativa, sobresalieron por su rendimiento buenas características de grano y bajo daño por Cercospora sp., el ICGS(E)-2, Robust33-1, ICGS(E)-8, ICGS(E) e ICGS(E)-5.
Thirty two peanut genotypes, supplied by the ‘International Crops Research Institute for the Semi-Arid Tropics’ (ICRISAT), were tested in order to observe their performance and to select the cultivars with highest yields and best grain characteristics in Turrialba, Costa Rica. A Randomized Complete Block Design with four replications was used. The average yield of the 32 genotypes was 3523 kg of grain/ha. Most of them produced from 40 to 45 pods/plant and the grain/pod ratio varied from 70 to 78%. Although the grain yield variation was not significant among most of the genotypes, some with outstanding yields, with good grain quality and lesser damage by Cercospora sp. were: ICGS (E) – 2, Robust 33 – 1, ICGS (E) – 8, ICGS (E)- 15 and ICGS (E) – 5.
