Griffing's methods comparison for general and specific combining ability in cucumber. [PDF]
ScientificWorldJournal, 2012 A comparison among two forms of half-diallel analysis was made. The different half-diallel techniques used were Griffing's model I, method 2 and 4. These methods of diallel analysis were found to be interrelated. However, as Griffing's model I, method 4 partitioned heterosis into different components as well as gave information about combining ability ...

General and specific combining ability in Serrasalmidae
Aquaculture Research, 2018 This work was carried out to predict the combining abilities, both general and specific, for performance traits and bodily yields of Serrasalmidae. Ninety‐six 30‐day‐old juveniles were purchased from two commercial fish farms, 12 of each of the following eight genetic groups: pacu, pirapitinga, tambaqui, tambacu, tambatinga, patinga, paqui and piraqui.

A Study on the Specific Combining Ability in Several Inbred Lines of Maize
PLANTA TROPIKA, 2023 Maize is a cereal crop essential to fulfill the need for food and support global food security programs. Maize hybrid varieties play a very significant role in increasing maize production. Objectives of the research were to obtain a tester, which is consistent in identifying inbred lines with a high specific combining ability, and to obtain prospective

Biplot AMMI graphic representation of specific combining ability [PDF]
Cropp Breeding and Applied Biotechnology, 2002 Specific combining ability (SCA) is a genetic property of great interest in breeding programs aiming at hybrid cultivars. It enables assessment of the genotype combinations most promising for hybridization. This study presents the foundations of biplot graphic display associated with AMMI (additive main effects and multiplicative interaction) analysis,

Components of Specific Combining Ability Estimated from Strain and Breed Crosses in Chickens ,
Poultry Science, 1967 Abstract INTRODUCTION HETEROSIS, the increase in performance of crosses over parental strains, has generally been found in fowl for chick livability, early growth rate, age at sexual maturity, egg production and at times for adult livability. Degree of heterosis seems to be positively associated with genetic diversity of the parental strains.

Specific Combining Ability Among Dairy Sires for Type Traits
Journal of Dairy Science, 1973 Abstract Type records of 12,030 Canadian Holstein cows in first lactation with both sires and maternal grandsires in a group of 200 artificial insemination sires were analyzed to determine the importance of specific combining ability. Data were adjusted for effects of round of classification, age, stage, and season of classification before final ...

RECURRENT SELECTION FOR SPECIFIC COMBINING ABILITY FOR YIELD IN FOUR SLICING CUCUMBER POPULATIONS [PDF]
HortScience, 1996 Plant breeders often measure selection progress for yield by measuring the hybrid performance (combining ability) of a breeding line. This information is used to develop breeding lines with higher combining ability. The objectives of this study were to measure the specific combining ability for yield traits over three selection cycles from four slicing

Use of a Full Diallel Cross to Estimate General and Specific Combining Ability in Chickens ,
Poultry Science, 1965 Abstract INTRODUCTION THE diallel cross has become a common method of analyzing intra-specific genetic variability among crosses (partial diallel) or among parental subpopulations and their crosses (full diallel). The breeder needs the full diallel to determine whether crossing per se is of value in improving productivity.
