All advances in genetics in the development of new cultivars are transferred to grain
production, for the benefit of the farmer, through the seeds. The use of high quality seeds of
known and reliable origin are basic prerequisites for management strategies aimed at
increasing productivity, competitiveness and sustainability of rice cultivation. Harvesting at
the right time has fundamental importance in order to obtain better quality seeds with
higher yields. Early harvesting, with high humidity, increases the proportion of malformed
and chalky seeds. The objective of this study was to evaluate the harvest period of Epagri
rice cultivars in order to estimate the moment that the seeds presents better physiological
quality and estimate the relationship between seed quality traits. The experiment was in a
randomized blocks with three replicates. The cultivars used was Epagri 106, Epagri 109,
SCSBRS Tio Taka, SCS116 Satoru, SCS118 Marques, SCS121 CL and SCS122 Miura. Five
harvests were done from 25 to 45 days after flowering (DAF). It can be verified that for all
long-cycle cultivars, the most suitable period for harvesting was when the seed moisture was
between 20-24%, around 35-40 DAF, during which period the seeds showed higher vigor,
germination, percentage of whole seeds and lower level of chalky. While the medium-cycle
cultivar Epagri 106, with the exception of germination, all other traits behaved similarly at all
harvest times. Early harvests were inadequate, which resulted in high humidity and low
physical and physiological seed quality. Percentage of whole grains presented direct relation
with germination and seed vigor. MenosAll advances in genetics in the development of new cultivars are transferred to grain
