Genotype x environment interaction for yield of rice hybrids and inbred varieties in Venezuela
نویسندگان
چکیده
Performance tests in multiple locations are essential to study the genotype x–environment interaction, as well identify superior genotypes and testing locations. The objective of this was evaluate adaptability stability rice hybrids inbred varieties for grain yield. Six experiments were conducted rice-producing areas Venezuela using a randomized complete block design during dry season 2015-2016. ANOVA detected significant differences genotype, location, genotype-by-location highlighting hybrid by location interaction. Lin Binns model identified ‘RHA-180’ ‘HL23035H’ ‘Soberana Fl’ variety adapted stable. In GGE biplot model, first components significant, together explained 82 % total variability. stable, whereas considered “ideal genotype”. ‘SD-20A’ displayed high performance intermediate stability. two mega-environments differed having best performing Fl’. Plot 199 most representative locality varieties, INIA Guárico discriminated better genotypes. Both models coincided regarding identification stable Venezuela. Nonetheless, while it easy efficient apply SREG more detailed, effective, informative.

Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...
