Abstract

fetched live from OpenAlex

Genotype x cropping system interactions frequently occur in common bean (Phaseolus vulgaris L.) cultivars in intercrops with maize (Zea mays L.). The purpose of this study was to determine the cropping system suited for selecting bean cultivars for production in an intercropping system. Sixty-three genotypes of common bean were evaluated in sole and intercrops across three environments, for seed yield and other characters. Cropping system significantly affected yield, pods per plant and seeds per pod. Genotype x cropping system was significant for several traits, including yield. Heritability estimates were comparable between cropping systems for all traits except pods per plant and canopy width. For most traits, predicted direct response to selection for a trait in one cropping system was greater than predicted correlated response to selection in the other. Using a selection intensity of 25%, the majority of high yielding lines selected in sole crop also emerged high yielding in intercrop. Selection of bush bean cultivars intended for intercropping should initially be conducted under sole crop conditions. Key Words: Genotype x cropping interaction, Phaseolus vulgaris, Zea mays RÉSUMÉ Les intéractions entre génotypes et systèmes de cultures apparaissent fréquemment dans la combinaison des variétés du haricot commun (Phaseolus vulgaris L.) et du maïs (Zea mays L.). L'objet de cette étude était de déterminer le système de cultures adéquat pour la sélection des variétés des haricots pour un système de production en interculture. Soixante trois génotypes du haricot commun étaient évalués en monoculture et interculture dans trois types d'environnements pour les rendements en graines et autres caractères. Le système de cultures affecta significativement le rendement, le nombre de gousses par plante et les graines par gousse. L'intéraction génotype-système de cultures était significative pour plusieurs traits y compris le rendement. Les estimation d'héritabilié étaient comparables entre systèmes des cultures pour tous les traits à l'exception du nombre de gousses par plantes et la largeur de la couverture végétale. Pour la plupart des traits, la réponse directe prédite à la sélection d'un trait dans un système de cultures était grande que la réponse corrélée prédite à la sélection dans un autre système. Utulisant une sélection d'intensité 25%, la majorité de races à rendement élévé sélectionnées en monoculture émergèrent à rendement élévé en interculture. La sélection des variétés sauvage de haricot pour l'interculture devra être testé initiallement dans les conditions de monoculture.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
