Abstract

The bean cultivation is considered as a commodity and strategic for the rural development of the countries, occupying the second place at world level, for its content of proteins and hydrates of carbon, it also contributes to the nitrogen fixation biological to the soil. This research was carried out in the parish of Veintimilla of the Canton Guaranda to an altitude of 2622 mls, in soil franc and 696.31 mm of precipitation during the whole cycle of the cultivation. Eight treatments of bean were evaluated in alone crop. The seed planting was 12/19/2011, in a system of reduced farm, in rotation after corn. 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 pods and in poscosecha. The most outstanding results were for tender it was selected to the line T1; good load of pods, (big, healthy, thick and color of spotted red grain), it is tolerant to deceases. For dry grain the biggest acceptability was for the lines T6: I – 426 Canary for its yellow color of the grain, its good price in the national market, tolerant to deceases foliares; T8 for their brilliant red color, I seed thick, it forms round and of good acceptability in the market. Finally this investigation it allowed to select lines of bean superior to the control local bean Canary that is late, very aggressive for associate with corn and susceptible to the yust
