Phenotypic and genotypic stability for peanut pod yield and yield components under varying environments in Egypt
Thirteen exetic and advanced peanut breeding genotypes, and two check cultivar (Giza/6 and Ismailia2) as a check cultivar were evaluated for yield and yield component under eighteen divers environments condition. The obtained results revealed that Pooled analysis of variance indicated, highly significant differences among genotypes, years, locations and sowing dates as well as all interactions between them for all characters, providing evidence for the necessity of testing studied genotypes in multiple environments. Phenotypic stability parameters indicated that genotypes (4 and 6) were classified as highly adapted to favorable environments for pod yield ard/fed. and oil percentage as well as line (Ismailia/2) for pod yield ard/fed. The most desired and stable lines showed genotypes (2,5 and 10) for pod yield ard/fed. under wide range variable environmental conditions; genotypes (2and 5) for shelling percentage and pod yield ard/fed. as well as genotypes (5 and 8) for 100-seed weight and oil percentage. Genotypic stability estimates showed that, the most average stable genotypes were, genotypes (2 and 10) for pod yield ard/fed., genotype (7) for 100-seed weight, genotypes (11 and 13) for shelling percentage as well as genotypes (9 and 12) for oil percentage. It is worthy to mention that, the phenotypic and genotypic of stability are quite similar for describing stability in peanut genotypes (2 and 10) for pod yield ard/fed. and genotype (13) for shelling percentage. It is therefore suggested that these genotypes may be recommended to be included in any breeding program for improving peanut pod yield stability under different environments.
