Evaluation and Comparative Analysis of Meteorological Data, Moisture Content, and Rice Panicle Threshability

Harvesting and threshing are crucial processes that influence the quantity, quality, economic efficiency of rice production. Therefore, threshability varieties is an important agronomic trait for breeding programs. However, selection hardly standardized. With application improved meter, four local temperate japonica was determined during ripening phase (DAF 37–60) in three consecutive years. Panicle force (TF N) measured parallel with seed moisture content (MC) to describe differences habits genotypes. Shapes separation pilei were observed relationship different types grain shattering found. The patterns genotypes found as quite stable along these periods. Moreover, correlation among TF, MC, 5-day averages meteorological parameters determined. Precipitation, Tmean, Tmax, relative humidity had a significant on MC. Based our results, MC low but positive TF (0.312 *).
