In this period, 100 genotypes were evaluated at 48</p><p>environments at nine Central America and the Caribbean</p><p>countries. The RN1 values represents the specific genotype.s</p><p>probability increase over the mean yield, specified by a control.</p><p>The study allowed to identify genotypes with low environment</p><p>interaction and of normalized response varying from good to</p><p>average (0.6 ≥ RNI < 0.9) according with the control. The</p><p>stability and the confidence degree, regarding to the regional</p><p>control HB-83, was determined every year. In addition, the</p><p>same analysis was performed with 12 genotypes in common at</p><p>least in two year of this phase. The combined analysis indicated</p><p>that 25% of genotypes showed a RNI = 0.8, these genotypes</p><p>were CM 933-133, XM 7706 and XM 7708. Six of them (50%)</p><p>showed standard RNI, outstanding the H-59 and CB-HS-9 with</p><p>RNI values of 0.73 and 0.75, respectively; the other 25%</p><p>presented low RNI, less than 0.6. The HB-83, CB-HS-11, HN-</p><p>12 and Trop E 103 were identified as hybrids with low</p><p>genotype-environment interaction by the AMMI analysis. Both</p><p>analysis allowed to verify that HB-83 is still a competitive and</p><p>current regional control due to its high production and good</p><p>stability throughout contrasting environments.</p>}, number={2}, journal={Agronomía Mesoamericana}, author={Camargo-Buitrago, Ismael and Gordón-Mendoza, Román and Fuentes, Mario}, year={2003}, month={Sep.}, pages={129–134} }
