Inheritance of resistance to maize lethal necrosis in tropical maize inbred lines [PDF]

Frontiers in Plant Science
Maize (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 ...

A new partial diallel model adapted to analyze reciprocal effects in grain yield of maize

Crop Breeding and Applied Biotechnology, 2019
Comparison between two distinct groups using a partial diallel and considering reciprocal effects has not been described in the scientific literature, limiting diallel analysis results.

SASHAYDIALL: A SAS Program for Hayman's Diallel Analysis [PDF]

Crop Science, 2018
Different methods of diallel crossing are commonly used in plant breeding. The diallel cross analysis method proposed by Hayman is particularly useful because it provides information, among others, on additive and dominance effects of genes, average degree of dominance, proportion of dominance, direction of dominance, distribution of genes, maternal ...

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis. [PDF]

Adv Sci (Weinh)
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Quantitative Insights into the Genetic Mechanisms of Crop Heterosis. [PDF]

Adv Genet (Hoboken)
Inheritance patterns of genomics‐downstream molecules, including transcripts, proteins, and metabolites, are analyzed in hybrid crops. The additive effect, which describes mid‐parent level, is a predominant inheritance pattern in crop heterosis and can be used to improve breeding efficiency of high‐yield hybrid varieties.

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 ...

Inbreeding depression of 28 maize elite open pollinated varieties

Genetics and Molecular Biology, 2002
The study of inbreeding depression is important for breeding strategies such as use of inbred progenies or extraction of inbreed lines. A diallel of 28 maize open-pollinated varieties was evaluated in 10 environments in the early 1990s. At the same time,

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 ...

Obtaining okra hybrids through partial diallel analysis

, 2021
The exploration of heterosis can be an efficient alternative to increase okra yield. The partial diallel strategy optimizes resources by guiding crosses based on genetic diversity between various genotypes.
