Somas de quadrados e hipóteses associadas ao modelo dialélico de Gardner e Eberhart Some insights into the sums of square and associated hypotheses of the Gardner and Eberhart diallel model

Ciência e Agrotecnologia, 2003
Quando o modelo estatístico não é ortogonal ou nos casos de desbalanceamento, existem diferentes critérios para a formulação de hipóteses que geram diferentes valores para as somas de quadrados.

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

Plant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Multi-triangular sampling plans for partial diallel crosses

, 1985
Partial diallel crosses based on multi triangular design (MTD) have been constructed and analyzed when the number of parental lines is of the form p(p-1)(p-2)(p-3)/24 with p as an integer greater than 4.

Genetic Analysis of East African Sorghum Genotypes for Yield Components and Iron and Zinc Composition

Plant Breeding, EarlyView.
ABSTRACT Sorghum [Sorghum bicolor (L.) Moench] is a vital cereal crop in dry regions worldwide. However, in sub‐Saharan Africa (SSA), grain yields from currently grown varieties remain low (< 1 ton/ha) and exhibit variable nutrient composition. Therefore, the objective of this study was to undertake a genetic analysis of selected East African‐adapted ...

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

New Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.
