INTRODUÇÃO:

Common bean (Phaseolus vulgaris) is a species with economic, social and cultural importance to Brazil, and it exercises influence under commercial balance, promotes job generation, besides to serve as base in Brazilian alimentation. This scenery places Brazil as higher producer and consumer of this grain in world. (Phaseolus vulgaris)

OBJETIVO DO TRABALHO:

Aim of this investigation was to evaluate productive potential of 14 common bean (Phaseolus vulgaris) genotypes, being measured 100-seed weight and grain yield. (Phaseolus vulgaris)

MÉTODOS:

Study was conducted in experimental area located in Centro de Treinamento em Irrigação (CTI) of Universidade Estadual de Maringá (UEM), during 2008 season. Fertilization was carried out based in soil analysis and crop exigency. Plants were grown in field conditions with minimum/maximum temperature of 15.2/32.7ºC, and relative humidity was 48/74%, respectively. Experimental design used was randomized blocks, with 14 genotypes (IAPAR 81, IPR Tangará, IPR Uirapuru, BRS Campeiro, CHC 9729, CHP 9859, GEN C2-1-1, GEN C2-1-3, SM 1007, SN 1207, CNFC 10408, CNCF 10429, LP 0403, and LP 0472). Experiment was composed of 4 blocks, and each plot with 5x5 m (diameter x width), being used spacing of 1 and 2 m among plots and blocks, respectively. In this study were evaluated 100-seed weight and grain yield. Data were analyzed employing a variance analysis, and using Scott-Knott test at 5% level of probability. Standard errors were also calculated in all treatments evaluated.

RESULTADOS E DISCUSSÃO:

Results linked to 100-seed weight present statistically three groups, being group with better performance composed by IAPAR 81, IPR Tangará, and SN1207 genotypes, and higher value was presented by IPR Tangará genotype with 27.7 g. In intermediary group were distributed BRS Campeiro, CNFC 10408, and CNFC10429 genotypes. Additionally, other genotypes were equal statistically and 100-seed weight oscillated between 19.6 and 22.5 g. In relation to grain yield to statistical analysis revealed presence of three groups, being composed first group and higher yield by IAPAR 81, IPR Tangará, IPR Uirapuru, BRS Campeiro, CHC 9729, CHP 9859, SN 1207, and CNFC 10408 genotypes. However, genotypes GEN C2-1-1 and GEN C2-1-3 were that presented lower yield.

CONCLUSÕES:

In 100-seed weight presented three groups, and better results were showed in IAPAR 81, IPR Tangará, and SN1207 genotypes. For grain yield, IAPAR 81, IPR Tangará, IPR Uirapuru, BRS Campeiro, CHC 9729, CHP 9859, SN 1207, and CNFC 10408 genotypes were statistically equals and higher, if compared to other genotypes.
