“…The magnitude of the GEI sum of squares was 1.07 times larger than that for genotypes, which suggests that there were major differences in genotypic response across environments. This report is in harmony with the findings of Blanche et al (2009), Hasan et al (2011 and Tariku et al (2013).…”

The adaptation of hybrid rice varieties mostly are in specific location and season, but there are some of the varieties have a wide adaptation then adopted by the farmer in the large area. Replicated yield trials were conducted to study the stability of hybrid rice yield and identify the best location to optimize their yield per ha. The trials were conducted in three location such as Sukamandi, Salatiga and Malang during two seasons in 2011. Data across location and season were analazed by using AMMI and Eberhart Russel methods. The AMMI analysis showed that the IR79156A/PK88 was adaptable to favorable environments but unstable. This hybrid is always performing well and produce the higher yield compare to check variety. Some of other hybrids were good only in specific location, i.e. IR62829A/BP2280-1E-12-22 and IR58029A/ BP2280-1E-12-22. Those hybrids produced higher yield in Salatiga and Malang, respectively. Seem to AMMI analysis, the result of Eberhart and Russell method also showed that IR79156A/PK81 was the best hybrid with regression slope (b) around 1 with the yield average higher than average of all hybrids. It indicated that this hybrid has a wide adaptation and probably can be cultivated in the wider ecosystem.

“…Genotype-environment interaction for yield is a common phenomenon that has been demonstrated in multienvironment trials with a lot of species of crop plants (Fox et al 1997;Kang and Kumar 2000;Mekbib 2003;Blanche et al 2009) including potato (eg. Tai 1971Mallory and Porter 2007;Mulema et al 2008).…”

Stability Analysis of Agronomic Traits in Potato Cultivars of Different Origin

et al. 2014

Potato (Solanum tuberosum ssp. tuberosum) cultivars are expected to express a stable level for traits important for growers and consumers. To investigate how this expectation was met by a set of 21 cultivars bred in Hungary, Poland and Spain, 2-year field experiments were carried out in these countries for the evaluation of tuber yield, starch content and yield, and occurrence of secondary growth of tubers. Stability in an agronomic sense was evaluated by the analysis of genotype by environment interaction (GE) using the Scheffé-Caliński mixed model. Unstable trait expression was indicated by the statistically significant share of GE in the variability contributed by a specific cultivar. This instability could lead to either complete or partial unpredictability. Stable trait expression was observed for 6-11 cultivars, depending on the trait. A significant genetic factor, which indicates broad adaptation, was rarely found. Stable expression of tuber yield occurred together with stable or predictable expression of both starch content and yield. Unstable expressions of tuber and starch yield were also associated. The stability or instability of secondary growth was not associated with stability or instability of the other measured traits. Analysis of GE interaction was useful for identifying stable or unstable responses and revealed the presence of incomplete stability or partial unpredictability as intermediate types of reaction.Resumen Se esperaría que las variedades de papa (Solanum tuberosum spp. tuberosum) expresen un nivel estable de caracteres importantes para productores y consumidores. Para investigar como esta expectativa pudiera darse en un juego de 21 variedades de Hungría, Polonia y España, se llevaron a cabo experimentos de campo durante dos años en estos países para la evaluación de rendimiento de tubérculo, rendimiento y contenido de almidón, y la presencia de crecimiento secundario de tubérculos. Se evaluó la estabilidad, en un sentido agronómico, mediante el análisis de la interacción genotipo-medio ambiente (GE), usando el modelo de la mezcla Scheffé-Caliński. La expresión de un carácter inestable se indicó por la significancia estadística de GE en la variabilidad proporcionada por una variedad específica. Esta inestabilidad podría conducir ya fuera para imprevisibilidad completa o parcial. La expresión de un carácter estable se observó en 6-11 variedades, dependiendo del carácter. Raramente se encontró un factor genético significativo que indicara amplia adaptación. La expresión estable de rendimiento de tubérculo se presentó junto con la expresión estable o predecible tanto con el contenido como con el rendimiento de almidón. También se asociaron expresiones inestables de rendimiento de tubérculo y almidón. La estabilidad o inestabilidad de crecimiento secundario no se asoció con estabilidad o inestabilidad de los otros caracteres medidos. El análisis de la interacción GE fue útil para la identificación de respuestas estables o inestables y reveló la presencia de estabilidad incompleta...

“…Cybonnet (PI 636726) and Saber (PI 633624) are both tropical japonica US long grain rice cultivars that have exhibited fissure resistance in past studies (Pinson, 2004; Blanche et al, 2009; Pinson et al, 2013). Both Cybonnet and Saber are sd‐1 semidwarfs (McClung et al, 2004; Gibbons et al, 2006).…”

“…Cybonnet was selected out of a Cypress//'Newbonnet’/‘Katy’ cross (Gibbons et al, 2006), whereas Saber was from ‘Gulfmont’/RU8703196//‘TeQing’ and was released for improved disease resistance (McClung et al, 2004). The only known FR parent in these pedigrees is Cypress, whose FR has been attributed to its low hull permeability slowing moisture absorption (Jodari and Linscombe, 1996; Waggoner et al, 2003; Blanche et al, 2009). It has been proposed that Saber's FR might result from the high endosperm diffusivity observed in its indica parent, TeQing (Waggoner et al, 2003).…”

Kernel fissures in rice (Oryza sativa L.) caused by pre‐ or postharvest stresses are the leading cause of breakage among milled rice. Such breakage causes economic losses for producers, millers, and marketers. Five quantitative trait loci (QTLs) for kernel fissure resistance (FR) were identified among a set of 271 recombinant inbred lines derived from ‘Cybonnet’ × ‘Saber’ (CS‐RILs) phenotyped using seven replications of seed harvested from four different environments (year–locations). Use of single‐nucleotide polymorphisms identified additional polymorphism and allowed for more precise mapping of three FR QTLs previously identified using a limited number of simple sequence repeats. Two QTLs were newly discovered in chromosomal regions not previously known to contain genes affecting FR. Saber contributed the FR allele at these newly identified FR QTLs, making them the first FR QTLs not traceable to the ancestral cultivar ‘Cypress’. Fissure resistance among the CS‐RILs proved to be independent from differences for plant height, days to heading, and kernel morphology (i.e., length, width, thickness, and weight). The FR QTLs from Cybonnet and Saber were additive, with stronger levels of FR resulting from pyramiding of FR alleles from both cultivars.
