Genetic distance and specific combining ability in cassava [PDF]

Euphytica, 2016
Cassava (Manihot esculenta Crantz) is an important source of energy in the tropics. Its starchy roots are valuable for food security as well as for different industries. Cassava is an outcrossing crop and its breeding is based on the use of heterozygous progenitors.

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 ...

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.

Estimation of general combining ability, specific combining ability and heterosis among selected rice (Oryza sativa L.) genotypes [PDF]

World Journal of Advanced Research and Reviews, 2022
Rice is the most important cereal crop and is primary source of calorie for Nepalese. Though, few rice varieties have been released for cultivation among farmers, most of them are low yielding so are not preferred by the farmers. So, broadening the genetic base of rice is an important intervention that can be done to increase productivity.

General and specific combining ability in sweet sorghum [PDF]

Crop Breeding and Applied Biotechnology, 2018
In breeding of sweet sorghum hybrids, non-additive genetic effects are important in phenotypic expression of the traits of interest. The aim of this study was to evaluate the general combining ability (GCA) of sweet sorghum lines and the specific combining ability (SCA) of the hybrids for agronomic and technological traits.

Watermelon general and specific combining ability

Comunicata Scientiae, 2019
The combining ability of six watermelon genotypes was estimated in a diallel cross scheme (6x6), including genotypes JNY (1), ‘ORA’ (2), ‘KOD’ (3), ‘SOL’ (4), ‘CHG’ (5), ‘PEA’ (6) and all possible hybrids between them. A randomized complete block design (RCB) was used, with 36 treatments, three blocks, and plots with five plants.

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.

Heterosis and Combining Ability Analysis of Fruit Yield, Early Maturity, and Quality in Tomato

Agronomy, 2021
Heterosis and combining ability are two important considerations in the utilization of heterosis, which can be used to generate excellent hybrid resource candidates and is very important in conventional hybrid breeding.

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 ...

General and Specific Combining Ability for Quantitative Characters in Sunflower

Journal of Agricultural Science, 2011
Seven sunflower (Helianthus annuus L.) inbred lines were crossed in 77 half diallel to obtain 21 F 1 hybrids.These lines were used to estimate general combining ability (GCA) and specific combining ability (SCA) effects for yield, head diameter, 1,000-seed weight, plant height and oil content in order to select suitable parents for hybridization and ...
