Yield stability in long-term released maize hybrids FAO 100 and 200

The purpose of this study was to assess changes in yield stability of maize hybrids during a 20-year period and to relate them to yield changes. The data on FAO 100 and FAO 200 hybrids, released by the former Yugoslav Committee for Releasing Varieties, were utilized. Most of the released hybrids fell into the first and the second stability group (Francis and Kannenberg 1978). The bi values (Finlay and Wilkinson 1963) of the released hybrids, except two from FAO 100 and four from FAO 200 group, did not differ significantly from 1.0. Also, all but one from FAO 100 and one from FAO 200 released hybrids did not differ in sigma(i)(2) value (Shukla 1972) significantly from 0. Values of b(i) and sigma(i)(2) stability parameters changed only slightly during the 20-year period. During the same time the yield of the FAO 100 hybrids did not change. tn the FAO 200 group the yield increased, but the genetic gain was not significant. The stability parameters were not in a significant correlation with the yield. [References: 11
