Characterization morfoagronomica of four varieties of Saccharum sp. Hybrid l- under three conditions of different handlings

Abstract

With the objective of characterizing morphs agronomics four sugar cane variety in commercial exploitation in the caners areas of the Sugar Company Antonio Sánchez: My5514, Co997, C323-68 and C8612, under three different management conditions: of registered seed bank, garden of varieties and of production, the following variables were measured: height of the shaft (cm), diameter of the shaft (mm), number of active leaves, inter knot number for shaft, longitude of the inter knot in 10 shafts and mass of the shafts (kg.). The results reveal that all the varieties under production management conditions reach the smallest values of height, mass, diameter of the shafts, number of active leaves, number and longitude of the inter knot, that reached only between 22 and 31% of their potential yield. Under production conditions, the varieties C323-68 and the My5514 were those of smaller potential yields.
