Jalo Precoce, Pérola, Carioca and Michelite cultivars of Common Bean (Phaseolus vulgaris L.) were used to estimate natural hybridization rates. Two experiments were carried out, one in the "wet"season and the other in the 1997/1998 "fall-winter" season. Randomized complete blocks in a split plot scheme were used, with three replications. Four row spacings (0.20 m, 0.40 m. 0.60 m and 0.80 m) were randomized within the plots. Cultivars with a recessive genetic trait were planted in subplots, in alternate rows, with the IAPAR 44 cultivar, which has vilet flowers and hypocotyl determined by dominant genes. In the "wet" season the Jalo Precoce , Pérola, Carioca and Michelite cultivars had average natural hybridization rates of 1.23, 1.34, 1.25 and 0,71%, respectively. The mean percentages were 0.82, 0.75, 0.79 and 0.76% for Jalo Precoce, Pérola, Carioca and Michelite cultivars in the "fall-winter" season, respectively. The estimates of natural hybridization had magnitudes which ranged from 0.71 to 1.66%. |

This work aimed to analyze the adoption probability of yellow pulp cassava varieties for fresh consumption by farmers of four states (Maranho, Pernambuco, Piaui and Ceara) located in the Northeast of Brazil. Thirty-five participatory tests were performed in 28 smalholder communities. The varieties BRS Dourada, BRS Gema de Ovo, Abobora, Cacau, Cacau Amarelo, Amarelo I, Amarelo II, Aipim Cacau, BRS Rosada and Vermelhinha were evaluated. Several criteria for variety selection were identified. However, yield, root length, quality and starch content of the roots were the principal criteria used. There were differences in the variety preference among states. In Maranho, the varieties Amarelo I and Amarelo II presented the higher probability of acceptance. In Pernambuco and Piaui the varieties BRS Dourada, BRS Gema de Ovo and Abobora were preferred. In Ceara the most accepted varieties were BRS Cacau and BRS Gema de Ovo. The results showed that the participatory selection tests are efficient to assess the farmer preferences for varieties. In addition, using this approach the decisions about the selected varieties are taken jointly by scientists and farmers increasing the probability of their final adoption. |
