“…One of the reasons is that, in this case, more pods were available and it was possible to use five pods per plot with three replications. In a similar study involving 95 common bean lines, with the use of ten pods per plot, the accuracy of the percentage of germination of seeds while still in the pods was similar to that obtained in the present study, i.e., 62 % (Lima et al, 2012).…”

“…Pryke (1978) observed variation in early germination in a series of common bean crosses grown in a greenhouse. Lima et al (2012) evaluated 95 common bean lines related to tolerance to excess moisture at harvest time. They observed that the main difficulty in selection of common bean lines for tolerance to high moisture at harvest is repeatability of the environmental conditions in the field from one crop season to another.…”

In common bean (Phaseolus vulgaris) harvesting is carried out in the field. It is therefore necessary that cultivars be tolerant to viviparity, i.e., germination of grains still in the pods. Study of the percentage of germination of beans in the pods under laboratory conditions, where humidity content is high, has been proposed. Furthermore, under question is whether the thickness of the pod wall affects water uptake by the pods and, consequently, viviparity. Thus, the aim of the present study was to verify if there is variance among progenies for viviparity and if it is influenced by pod thickness. We assessed the parents, Pérola and ESAL 686, the F1, and a number of segregating generations in two crop seasons, in relation to the percentage of germination of seeds in the pods (PGSP) and pod wall thickness (PWT), and data on individual plants were obtained. The same traits were also assessed using the F 2:3 , F 3:4 and F 4:5 progenies. Taking into account the genetic and phenotypic parameters estimates, especially the level of high heritability, selection to less viviparity in common bean has to be carried out to evaluate PGSP in progenies.

“…According to literature, if the harvest is accomplished late, natural degradation, grain breaking in the track system and great losses can occur if this period coincides with the rainy season [9]. Therefore, technologies that enable both uniform and early harvesting become essential for seed production.…”

The pre-harvest application of herbicides may impair seed quality. This way, this paper was conducted to evaluate the effects of the application of desiccant herbicides on the physiological quality of pigeonpea seeds. Six batches of seeds from plants desiccated with glyphosate were evaluated at doses: 1.125 (B1), 1.5 (B2) and 1.875 L·ha −1 (B3); and Gramocil (20% Paraquat + 10% Diurom) at doses: 1.5 (B4) and 2 L·ha −1 (B5), and a control which received no application (B6). Seed viability was assessed through the germination standard test, and vigor through the first germination count, accelerated aging, electrical conductivity, seedling length, seedling dry matter and biomass density tests. The experimental design was the completely randomized, with four replications. Data were submitted to variance analysis, and when significant effects were observed, the ScottKnott test was carried out at 5% probability using the SISVAR 5.1 software. The results showed that: a) the application of 1.875 L·ha −1 of glyphosate was harmful to pigeonpea seed viability and vigor, evaluated through the accelerated aging test; b) applications of glyphosate in a 1.875 L·ha −1 dose and Gramocil in 2 L·ha −1 resulted in low vigor according to the electrical conductivity test of seeds; and c) the seed vigor measured by the first count, seedling length, seedling dry matter and biomass density test was not influenced by the type of desiccant applied.

“…The significant interactions for progenies × generations and check cultivars × generations for the grain yield and yield per day traits show that the performance of the progenies did not coincide in the two generations. This result is common in studies performed on common bean in the region (Ferreira et al, 2015;Lima et al, 2013). The existence of the interaction is important; however, it is not possible to identify a specific cultivar for each time period or environment.…”

The cycle of the common bean crop is shorter than that of other species. Nevertheless, in Brazil, researchers have been attempting to shorten the cycle even more to allow three crops a year and obtain greater flexibility in crop management. The aim of this study was to investigate the viability of selecting lines with a shorter cycle and that have good grain yield coming from the same segregating population. To that end, crosses were made between a short cycle and normal cycle cultivars. In the F2 and F2:3 generations, progenies were separated into two groups based on short or normal cycle. After that, the progenies selected were evaluated in the F2:4 and F2:5 generations for grain yield, cycle, and yield per day. The mean of the short cycle progenies was 15% lower for grain yield and 10% lower in yield per day in relation to the normal cycle progenies. Furthermore, selection of lines among those of short cycle that have grain yield equivalent to the best normal cycle lines is of very low probability.
