| Descripción: | The stability and other characteristics of 20genotypes of rice, grown under dry-land and irrigationconditions, were evaluated. Statistical analyses wereconducted (AMMI and Biplot GGESREG) to estimatestability. For the dryland system, there were differences inyield, excelling FLAR 54-00, 38 IDIAP and Lajas 02-00.Total yield fluctuated between 61.8 and 68.0%, entire grainsbetween 43.6 and 56.5% and the white center between 1.5 and3.4%. The alkaline digestion showed ten genotypes withdegrees of dispersion between six and seven with lowtemperature of gelatinización, eight with degrees from 4 to 5considered intermediate. FLAR 54-00 responded better to theenvironmental. Prosequisa, CHI 32-10 and CHI 45-23 showedthe poorest behavior. The model Biplot GGESREG identifiedFLAR 54-00, FLAR 198-00 and Fedearroz 50 as stablegenotypes. For the irrigation system, statistical DMS (P<0.05)indicated differences in yield, standing out IDIAP 38, P-3621and Fedearroz 50. The quality of grains showed total yieldbetween 65.8 – 70.9%, entire grains between 51.5 and 62.0%,and incidence of white center between 1.2 and 2.8%. In thealkaline digestion, nine genotypes presented degrees of sixand seven and ten with degrees from 4 to 5. IDIAP 38, P-3621and FLAR 54-00, responded better to the environmentalstimuli. Prosequisa, FLAR 195-00, CHI 49-16 and CHI 13-256 presented the poorest behavior. The stable genotypesunder irrigation were Fedearroz 50, 38 IDIAP and P-3621. |
