Abstract:

In this paper, the use of selective breading evolutionary process for improving the performance of GAs is evaluated. To accomplish this evaluation, the generalized tardiness flow shop scheduling (GTFS) problem is designated. A natural evolutionary GA and two selective breeding Gas are developed for evaluating their performances in solving the proposed problem. An extensive numerical experiment on total of 2250 randomly generated scenarios is conducted to compare the effects of selective breeding mechanism. The effects of the varieties factors on the solution of the algorithms are analyzed by t

Abstract:

SUMMARYGenes for adaptation to climatic conditions can have an impact on the expression of genes for agricultural productivity. This study tested the hypothesis that winter wheat cultivars registered in middle Europe (especially the Czech and Slovak Republics) during the period 1976–2009 were differentially adapted to different regions, reflecting selection for different allelic combinations. This was tested by analysing for the presence of alleles at the Rht and Ppd loci using molecular markers and gibberellic acids (GA) response tests. Four allelic variants (174, 192, 165 and 198-bp) were de

Abstract:

We analyze the performance of a genetic algorithm (GA) we call Culling, and a variety of other algorithms, on a problem we refer to as the Additive Search Problem (ASP). We show that the problem of learning the Ising perceptron is reducible to a noisy version of ASP. Noisy ASP is the first problem we are aware of where a genetic-type algorithm bests all known competitors. We generalize ASP to k-ASP to study whether GAs will achieve “implicit parallelism” in a problem with many more schemata. GAs fail to achieve this implicit parallelism, but we describe an algorithm we call Explicitly Parallel

Abstract Because drought continues to be a major limiting environmental factor in peanut (Arachis hypogaea L.) production, a breeding strategy for developing drought resistance was initiated in the early 1980's at the University of Georgia, Coastal Plain Experiment Station.

Rainout shelters were used between 60 and 120 days after planting to provide mid-season drought stress so that pedigree selection could be made within early-segregating generations.

Abstract:

Genetic gain followed by loss of diversity is not ideal in breeding programs for several species, and most studies face this problem for single traits. Thus, we propose a selection method based on Genetic Algorithms (GA) to optimize the gains for multi-traits that have a low reduction of status number (NS), which takes into account equal contributions from individuals as a result of practical issues in tree breeding. Real data were used to compare GA with a method based on a branch and bound algorithm (BB) for the single-trait problem. Simulated and real data were used to compare GA with a mul

Abstract:

Experiments with progenies of perennial species such as coffee are generally affected by the heterogeneity of residual variances between information repeatedly collected in space and time on the same individual.

Abstract:

The research of association between SNP markers and milk production trait of swamp buffalo was conducted to identify polymorphisms of SNP markers associated with milk/day trait of swamp buffalo. Milk/day data and hair bud samples were collected from 28 second parity milking swamp buffalo at 2 to 3 months at farmer farm in Prachinburi province for DNA extraction. DNA samples were used for 40 SNP genotyping by Mass Array method. The results showed 10 polymorphism SNP and associated with milk/day trait of swamp buffalo (P<0.01). They were 3 groups: 1) associated hormones (2 Leptin), 2) energy

The development of stone fruit varieties that meet modern production requirements is a labor-intensive process involving low yields of progeny obtained through controlled intraspecific and interspecific hybridization, which can take up to 25 years. The non-viability of hybrid seeds is caused by the abortion of the embryo that does not have time to complete its morphophysiological development and endosperm abortion in interspecific hybrids. It is possible to preserve hybrids having a unique combination of traits by removing embryos derived from interspecific and intergeneric crossing that are u
