Description

Genotypes that fasten their development cycle showed higher grain yield. Earlier start of flowering means higher soil water availability and lower maximum temperatures (middle of April), allowing to set more flowers and pods per plant and consequently higher grain yield. End of flowering started on May 19 in earlier genotypes. On this date the most hydrated genotypes are the ones with the longest growth cycle. On May 19 the genotypes with higher grain yield were at the end of flowering and showed lower predawn water potential. Grain yield showed a good correlation with all yield components except with the 100 Seeds Weight (100SW). End of flowering started on May 19 in earlier genotypes.
