Table 1 Descriptive statistics and analysis of variance for 8 traits: days to flowering (DTF), pod wall weight (PWW), whole-seed weight (WSW), whole-pod weight (WPW), 100-seed weight (SW100), seeds per pod (SPP), pod harvest index (PHI), and yield (YLD), in three water regimes in two year

From: Effect of drought stress on the genetic architecture of photosynthate allocation and remobilization in pods of common bean (Phaseolus vulgaris L.), a key species for food security
