Prediction of seed-yield potential of common bean populations
Earliest possible prediction of seed-yield potential of autogamous crop populations increases breeding program efficiency by saving time and resources. Alternatives for obtaining seed-yield predictions were compared by evaluating four common-bean populations in F1 and F2 generations together with the parents. Mean components (m + a’ and d) and variances were estimated. The potential of each pop...
متن کاملRelationships between Grain Yield and Accumulation of Biomass, Nitrogen and Phosphorus in Common Bean Cultivars(1)
Shoot biomass is considered a relevant component for crop yield, but relationships between biological productivity and grain yield in legume crops are usually difficult to establish. Two field experiments were carried out to investigate the relationships between grain yield, biomass production and N and P accumulation at reproductive stages of common bean (Phaseolus vulgaris) cultivars. Nine an...

Singh, S. P., Molina, A. and Gepts, P. 1995. Potcntial of wild coInmon bean for seed yield improvement of culdvars in the tropics. Can. J. Plant Sci. 75: 807-813. Thirty nine wild or weedy common bem (Plaseolus vulgarisL.) accessions, representing the two extremes of geographical range of distribution and domestication of cultigens in the Americas, were crossed to a highyielding, small-seeded c...
متن کاملSeed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملReview: Plant Growth Hormone Cytokinins Control the Crop Seed Yield
This review chronicles the development of the cytokinin research during the last 30 years. Cytokinin and auxin are the two major plant growth hormones that control virtually all aspects of growth and development in higher plants. The pathways for cytokinin biosynthesis and metabolism have been characterized by the identification of isopentenyl pyrophosphate transferase, cytokinin oxidases, cyto...
