1. Heritability of resistance to potato late blight in an F1 population of elite potato cultivars
ABSTRACT Phytophthora infestans is the most important disease in potato crops. Its control is based on the use of chemical products that have developed pathogen resistance and high economic and environmental impacts. To reduce these effects, the use of plant varieties or cultivars resistant to this pathogen has been proposed. The aim of this study was to eva

2. Genetic parameters estimation in common bean under weed plant competition
ABSTRACT The present study aimed to estimate genetic parameters of 20 common bean genotypes, commercial and regional bean on weed interference. The agronomic characters analyzed were: average stem diameter (ASD); average plant length (APL); number of pods per pot (NPP); number of locules per pod (NLP); number of grains per pod (NGP); percentage of empty locu

3. Evaluation yield and genetically factors in different cultivars of gladiolus
Abstract In order to suggest the best cultivars of gladiolus to grow in moderate regions of Iran, an experiment was carried out in a complete randomized block design in three replications with five cultivars of Gladiolus grandiflorus (‘Oscar’, ‘Red Advance’, ‘White Prosperity’, ‘Rose Supreme’ and ‘Lemon Drop’) at the ornamental plants res

4. Productive potential and castor bean selection of the FCA-PB cultivar progenies
ABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapte

6. Phenotypic variation and heritability of heading date in hexaploid oat
Abstract The onset of flowering is decisive to the reproductive success of plants. The objectives of this study were to characterize the phenotypic variation in heading date and estimate its heritability in segregating populations of oat (Avena sativa L.). F2 and F3 generations of two large populations, derived from crosses ‘URS Taura × Leggett’ and ‘

7. Genetic assessment of seed yield-related traits in superior hybrids of Paspalum plicatulum × Paspalum guenoarum
ABSTRACT This study aimed to estimate the genetic parameters, genetic correlations, genetic dissimilarity, and predicted gains with the selection of interspecific apomictic Paspalum plicatulum × Paspalum guenoarum hybrids in relation to seed yield traits. Nineteen genotypes that showed increased forage yield in previous studies were planted in a randomized

8. Heritability of morpho-agronomic traits in ornamental pepper
Abstract This study was conducted to identify the allelic interactions and genetic effects involved in genetic control of quantitative traits in Capsicum annuum. Six generations (P1, P2, F1, F2, BC1 and BC2) were used to study the variances, means and allelic interactions of 16 quantitative traits evaluated. The additive part of the phenotypic variance found

11. Genetic diversity among Brazilian okra landraces detected by morphoagronomic and molecular descriptors
ABSTRACT. The conservation of okra landraces [Abelmoschus esculentus (L.) Moench] in gene banks is essential for the success of their use in breeding programmes. This study evaluated the genetic diversity among okra landraces in Brazil based on morphoagronomic descriptors and AFLP markers. We studied 30 accessions of the vegetable gene bank of the Universida

12. Higher-precision experimental statistics for the selection of early and upright common bean lines
ABSTRACT. The development of early and upright common bean cultivars is necessary to meet the demand of producers. The objectives of this work were to evaluate more precise experimental statistics for the selection of early and upright common bean lines and identify the traits that provide better genetic differentiation between lines. For this purpose, 156 c
