(Chlorophyll fluorescence parameters in populations of two legume trees: Stryphnodendron adstringens (Mart.) Coville (Mimosoideae) and Cassia ferruginea (Schrad.) Schrad. ex DC. (Caesalpinoideae)). The aim of this study was to investigate the photosynthetic performance in populations of two legume tree species, Stryphnodendron adstringens (Mimosoideae), typical from Cerrado, and Cassia ferrugin...

In 1989, identical crosses (2-3 females within males) were performed with Picea abies (L.) Karst. in a greenhouse seed orchard at Biri nursery and in an outdoor seed orchard at Huse, 32 km north of Biri. Pollination began 17 days earlier in the greenhouse than outdoors at Huse. The potted grafts in the greenhouse were moved outdoors when the seed cones were no longer receptive. Twelve full-sib ...

Pseudomonas aeruginosa strain C2 was habituated to gentamicin by serial passage in broth containing increasing concentrations of the antibiotic and up to 250 microgram/ml. The resistant progenies differed from the parent strain in antibiotic susceptibility to two other aminoglycosides, colonial morphology, lytic phage patterns, phage adsorption, and agglutination with the seven Fisher's antiser...

Cocoa is an important crop in Cameroon, where it cultivated different areas, including marginal characterized by a rather low level of annual rainfall and marked dry seasons. In order to release cocoa varieties with good adaptation these conditions, nine full-sib progenies, already released farmers other producing areas the country, were assessed on twelve farm plots, set up 2006, Mbam et Inoub...

Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials-UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how the data at SRT could be used to predict the probabilities of genotypes reaching the UYT. Phenotypic...

En condiciones de invernadero se evaluó la calidad plántulas progenies selectas Leucaena esculenta. este sentido, durante 2017 estudió el crecimiento plantas en función árboles y edad después siembra (DDS) realizando análisis varianza pruebas medias (Duncan, 0.05). Las los DDS mostraron separadamente diferencias significativas (p ≤ 0.0001) las variables morfológicas área foliar. Los índices fue...

Maize forage is commonly used as silage in milk and beef cattle livestock production systems. Despite the wide variety of maize hybrids with high potential for grain production, few available have been developed exclusively aptitude. The present study aimed to select S3 progenies derived from single hybrid AS1572 based on combining ability traits topcrosses testers AG8025, 70.H26.1, MLP102. 135...

Breeding programs for improvement of sacha-inchi, Plukenetia volubilis L., generally aim to select individuals with greater seed yield since there is a strong correlation between and oil production. However, the manual removal husks evaluating this trait laborious costly, thereby discouraging breeding efforts. Accordingly, objective present study was estimate gains from indirect selection produ...

This article focuses on the development of the method for the genetic classification of agamospermous reproduction types in plants using sugar beet as an example. The classification feasibility is ensured by the use of isozymes as genetic markers allowing the identification of all three phenotypic classes in the progeny of individual heterozygous diploid plant and is based on different phenotyp...

Changing climatic conditions across Australia’s viticulture regions is placing increasing pressure on resources such as water and energy for irrigation. Therefore, there a pressing need to identify superior drought tolerant grapevine clones by exploring the extensive genetic diversity of early European in old vineyards. Previously, field trial, we identified drought-tolerant (DT) dry-farmed Cab...
