“…The effect of the interaction was very pronounced and the correlation of the Z-index in the 2 generations was negative. The occurrence of the progeny x environment interaction in the common bean crop has been frequently reported in the literature for grain yield (Rocha et al, 2009;Faria et al, 2009) or plant architecture (Moreto et al, 2007;Menezes Jr. et al, 2008) alone. The simultaneous action of the 3 traits must have contributed to an increased effect of the progeny x environment interaction, a condition that does not favor the identification of progeny with superior performance for the 3 traits simultaneously in more than 1 environment.…”

ABSTRACT. Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streaks bean type, and the BRS-Supremo cultivar, which has an erect plant architecture and black grains. In experiments conducted in the field, 47 progenies F 4:6 and F 4:7 were evaluated for two seasons for grain yield, plant architecture and grain type score. The variables were standardized and we obtained the sum of Z. The components of genetic variance in the average of the two environments were nil due to the progeny x environment interaction, which would hinder successful simultaneous selection of characters.

“…The mean grain yield obtained is shown in Table 3. The mean values fluctuated greatly from one generation to another, probably reflecting environmental variations between assessment periods, which are common for the crop in the region (Rocha et al, 2009). The estimates of the genetic correlations between the mean yield of the progenies in the pairs of generations were of small magnitude, ranging from 0.15 to 0.23, reflecting a high progeny  sowing time/generation interaction.…”

Multigeneration Index in the Within‐Progenies Bulk Method for Breeding of Self‐pollinated Plants

et al. 2015

This study proposes a strategy for improving the bulk method within progenies in self‐pollinated plants. The proposal focuses on the use of a multigeneration index, which considers the whole information across generations and the covariance among successive generations with a view toward identification of the best progenies. The results of the simulation and analysis of field data from common bean (Phaseolus vulgaris L.) were concordant and showed that the estimates of the accuracies were near 85% using the multigeneration index and 70% for the traditional methodology based on comparisons among progeny means of the generation F3:6 or of the last generation evaluated. Another advantage of the index is mitigation of the effect of the genotype × environment interaction, because it considers all the generations of assessment, thus involving interaction of the progenies with the sowing times. When selection is performed using only the information from the last generation assessed, performance of the progenies is inflated by this interaction. The efficiency of the strategy proposed leads to a 12% gain in relation to that which is normally used. This gain is considerable and equivalent in most cases to that which would be obtained through one additional selection cycle. It should be highlighted that this increase is obtained without any additional cost on experimentation, but simply through changing the procedure of identification of the best progenies after successive generations.

“…The interactions involving the genotype factor (p > 0.05) shows the low magnitude of the mean squared in relation to the factors time and storage condition. This means that the differences between the environmental conditions are larger than the other experimental factors (ROCHA et al, 2009). …”

Environment is crucial to the cooking time of beans

The objectives of this study were to understand how genotype, storage time, and storage conditions affect cooking time of beans and to indicate storage techniques that do not affect the cooking time. The grains were subjected to five different storage periods and six different storage conditions. The cooking time was estimated using the Mattson Cooker. The data were subjected to analysis of variance and a subsequent adjustment of simple linear regression for deployment of the interactions between the factors. Contrasts were used to determine the best levels of the factor storage condition. Genotype did not impact cooking time when the storage time and storage conditions were considered. Time and storage conditions affect the cooking time of beans in a dependent manner, but time of storage had the biggest influence. The best conditions for long-term storage of beans ensuring a smaller increase in cooking time is plastic storage at low temperatures. Thus, plastic freezer storage is a practical alternative for consumers.
