Caracterización morfológica y agronómica de germoplasma de fréjol voluble (Phaseolus Vulgaris L.) con investigación participativa en Cruz de Perezán, cantón Chillanes, provincia Bolívar

Abstract

The bean of crop at world level is a strategic activity for its contribution to the human feeding with proteins, hydrates of carbon and minerals, to the health and a key component in the production systems for the biological fixation of the nitrogen (FBN). This research was carried out in the community of Cruz of Perezán of the canton Chillanes to an altitude of 2400 m., and soil frank floor and 660 mm of precipitation during the cultivation cycle. Nine treatments of bean were evaluated in unicultivo (trellis). The seed planting was 03/17/10. The seed planting was carried in land conservation in rotation after tree tomato. A design of complete blocks was used at random. They were carried out variance analysis, test of Tukey to 5%, correlation analysis and lineal regression and evaluations participatives in formation of sheaths and in poscosecha. The most outstanding results were for tender it was selected to the line T1; for the longitude of sheaths, grain of size big, tolerant diseases. For dry the biggest acceptability was for the line T4 for the big size of the grain color red radical, intermediate cycle and cultivare I-426 Canary for the precocity, yellow color of the grain, tolerant to deceases and good price in the market. Finally this study allowed selecting germoplasma of bean inconstant superior to the control local bean Canary that is late and very aggressive with associate with the corn
