Inheritance of resistance to maize lethal necrosis in tropical maize inbred lines [PDF]
Frontiers in Plant ScienceMaize (Zea mays L.) production in sub-Saharan Africa can be improved by using hybrids with genetic resistance to maize lethal necrosis (MLN). This study aimed to assess the general (GCA) and specific combining ability (SCA), reciprocal effects, and ...

Modeling QTL-by-environment interactions for multi-parent populations [PDF]
Frontiers in Plant ScienceMulti-parent populations (MPPs) are attractive for genetic and breeding studies because they combine genetic diversity with an easy-to-control population structure.

Diallel analysis of length and shape of rice using Hayman and Griffing method
Open Agriculture, 2023 Length and shape of rice are important physical qualities that determine public acceptance of a variety and determine the price. Improvement of length and shape of rice requires information on the genetic parameters of these traits.

Combining Ability of Indonesian Tropical Maize in Two Different Seasons
AGRIVITA Journal of Agricultural Science, 2021 Testing an inbred cross for hybrid development requires a proper test cross method. The diallel is one crossing method to find out the magnitude of inbred combining ability, both general general (GCA) and specific combining ability (SCA) and specific ...

Linear models for diallel crosses: a review with R functions
Theoretical and Applied Genetics, 2020 A new R-software procedure for fixed/random Diallel models was developed. We eased the diallel schemes approach by considering them as specific cases with different parameterisations of a general linear model.

QTL Mapping in Outbred Tetraploid (and Diploid) Diallel Populations
bioRxiv, 2020 Over the last decade, multiparental populations have become a mainstay of genetics research in diploid species. Our goal was to extend this paradigm to autotetraploids by developing software for quantitative trait locus (QTL) mapping in connected F1 ...

Crop science, 2020 Doubled haploid (DH) lines are used in maize breeding to accelerate the breeding cycle and create homogenous inbred lines in as little as two seasons. These pure inbred lines allow breeders to quickly evaluate new cross combinations.

Heterosis in sweet sorghum [PDF]
Pesquisa Agropecuária Brasileira, 2018 : The objective of this work was to evaluate the potential per se of male-sterile and fertility-restorer lines of sweet sorghum (Sorghum bicolor), as well as to detail the heterosis manifested for some traits directly or indirectly related to ethanol ...

Multivariate diallel analysis by factor analysis for establish mega-traits.
Anais da Academia Brasileira de Ciências, 2020 In plant breeding, the dialelic models univariate have aided the selection of parents for hybridization. Multivariate analyses allow combining and associating the multiple pieces of information of the genetic relationships between traits.

Heterosis breeding for yield and its attributes in brinjal (Solanum melongena L.)
Electronic Journal of Plant Breeding, 2023 A study on heterosis in brinjal was carried out during the year 2019-20 at the Department of Genetics and Plant Breeding, Annamalai University. Seven genotypes were hybridised in full diallel fashion and the resultant 42 hybrids were evaluated along ...
