Assessment of yield stability in sugarcane genotypes using non-parametric methods

The evaluation of performance stability and high yields is essential for yield trials in different environments. This study was carried out to identifysugarcane genotypesthat have both a high mean cane yield, mesured in tons of cane per hectare (TCH), and stability across seven different environ...

This study was carried out to identifysugarcane genotypesthat have both a high mean cane yield, mesured in tons of cane per hectare (TCH), and stability across seven different environments, using 11 non-parametric statistical methods: Si (1), Si (2), Si (3), Si (6), NPI(1), NPI(2), NPI(3), NPI(4), RS, TOP and DE.

Este trabajo fue realizado con el objeto de identificar genotipos de ca?a de az?car de alto rendimiento, medido en toneladas de ca?a por hect?rea (TCH), y estables en siete diferentes ambientes mediante el uso de 11 m?todos estad?sticos no param?tricos: Si (1), Si (2), Si (3), Si (6), NPI(1), NPI(2), NPI(3), NPI(4), RS, TOP y DE. Los datos provienen del rendimiento en ca?a de 20 genotipos medido en siete localidades durante tres a?os en los ensayos regionales del Instituto Nacional de Investigaciones Agr?colas (INIA) de Venezuela. Los genotipos V99-213, V99-236 y V00-50 mostraron ser promisorio por su rendimiento y estabilidad de acuerdo a todos los estad?sticos no param?tricos. TCH present? asociaci?n positiva con los estad?sticos TOP, NPI(2), NPI(3) y Si (6). El an?lisis de componentes principales (CP) distingui? dos grupos. El primer grupo (G1) formado por los estad?sticos TOP, NPI(4), NPI(2), NPI(3), Si (3) y Si (6) que se encuentran bajo el concepto de estabilidad din?mica o agron?mica puesto que est?n asociados con el rendimiento. El otro grupo (G2) formado por NPI(1), Si (1), Si (2) , DE y RS que ubican dentro del concepto de estabilidad est?tica o biol?gica.
