The outlined objectives were: 1. To evaluate the 100 mestizos coming from the it crosses among the populations S2 (CIAP - 01 - E) for BRASILIA and their respective ones reciprocal. 2. To identify, through the evaluation of these mestizos, the best lines S2 that will be used in recombination in study. The 100 mestizos were sowed in block of 10, after drawing them treatments for their respective location in the land the rehearsal, the design experimental employee was of Simple Látice with two repetitions whose results were evaluated by means of the employment of the on-line program MSTAT-C. The experimental units were formed by a furrow of one surface of 4,20 m2, on which was sowed 0,70 m among furrow and to 0,40 m among plant, placing a seed for blow. During the phase of growth it was fertilized using as nitrogen source the Urea fractioned in two applications, the first one at the 15 days of age and the second to the 45 to have emerged the plants, applying 150 kg/ha. The registered variables were the following ones; days to the emission of spikes, days to the emission of pistils, days to the antesis, plant height and of ear height, ears for plant, ear lenght and ear diameter, number of kernel rows for ear, relationship seeds gopher, weight of 100 seeds and finally the yield in kg/ha. Approximately 2 % of the mestizos forms elite with productions that overcome the 4 000 kg/ha, following him 31 mestizos that gave productions that you/they go from 3 000 to 3 829 kg/ha. These results reveal achievements obtained in the application of the method of Reciprocal Recurrent Selection, as for improvement of the agronomic characteristics and of yield, of the populations used in the development of improved varieties. |
