Age-age correlation for early selection of rubber tree genotypes in São Paulo State, Brazil
(2005-10-01)
In a field trial involving 68 rubber tree (Hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth A and for age 7 to 12 ...
Complete replacement of the mitochondrial genotype in a Bos indicus calf reconstructed by nuclear transfer to a bos taurus oocyte
(2001-05-22)
Due to the exclusively maternal inheritance of mitochondria, mitochondrial genotypes can be coupled to a particular nuclear genotype by continuous mating of founder females and their female offspring to males of the desired ...
Genetic diversity in early-maturing soybean genotypes based on biometric and molecular parameters
(2014-01-01)
The objective of this study was to analyze the genetic diversity of 50 early-maturing soybean genotypes, destined for rotation with sugarcane, based on biometric and molecular data, as well as to verify the congruence ...
Identification and characterization of contrasting sunflower genotypes to early leaf senescence process combining molecular and physiological studies (Helianthus annuus L.)
(2016)
Leaf senescence is a complex mechanism ruled by multiple genetic and environmental variables that affect crop yields. It is the last stage in leaf development, is characterized by an active decline in photosynthetic rate, ...
Physiological response and earliness of soybean genotypes to soil base saturation conditions
(2020-01-01)
Low base saturation (V) is one of the major abiotic stresses in the Brazilian Cerrado. Given this scenario, it is important to evaluate different physiological responses of genotypes in environments with and without liming ...

Unravelling early events in the Taphrina deformans–Prunus persica interaction: an insight into the differential responses in resistant and susceptible genotypes
(Wiley Blackwell Publishing, Inc, 2017-08)
Leaf peach curl is a devastating disease affecting leaves, flowers and fruits, caused by the dimorphic fungus Taphrina deformans. To gain insight into the mechanisms of fungus pathogenesis and plant responses, leaves of a ...
Chemical Markers to Distinguish the Homo- and Heterozygous Bitter Genotype in Sweet Almond Kernels
(Multidisciplinary Digital Publishing Institute, 2020-06)
Bitterness in almonds is controlled by a single gene (Sk dominant for sweet kernel, sk recessive for bitter kernel) and the proportions of the offspring genotypes (SkSk, Sksk, sksk) depend on the progenitors' genotype. ...
High-throughput phenotyping allows the selection of soybean genotypes for earliness and high grain yield
(2022-12-01)
Background: Precision agriculture techniques are widely used to optimize fertilizer and soil applications. Furthermore, these techniques could also be combined with new statistical tools to assist in phenotyping in breeding ...
