“…Assuming that cotyledon pairs represent 90–92% of unit seed weight (Sexton et al . ), this results in relative growth rates ranging from 0.13 to 0.16 mg mg −1 d −1 , which is comparable with our reported range of 0.12–0.15 mg mg −1 d −1 (Table ). Final unit seed weight ( W s ) ranged from 0.18 (Jamapa) to 0.54 g (Calima), with values for both parental lines well within previously reported values (White et al .…”

The lack of dependable morphological indicators for the onset and end of seed growth has hindered modeling work in the common bean (Phaseolus vulgaris L.). We have addressed this problem through the use of mathematical growth functions to analyse and identify critical developmental stages, which can be linked to existing developmental indices. We performed this study under greenhouse conditions with an Andean and a Mesoamerican genotype of contrasting pod and seed phenotypes, and three selected recombinant inbred lines. Pods from tagged flowers were harvested at regular time intervals for various measurements. Differences in flower production and seed and pod growth trajectories among genotypes were detected via comparisons of parameters of fitted growth functions. Regardless of the genotype, the end of pod elongation marked the beginning of seed growth, which lasted until pods displayed a sharp decline in color, or pod hue angle. These results suggest that the end of pod elongation and the onset of color change are reliable indicators of important developmental transitions in the seed, even for widely differing pod phenotypes. We also provide a set of equations that can be used to model different aspects of reproductive growth and development in the common bean.

“…2). Common bean seed color and seed shape are the most prominent indicators of genetic variability and consumer habits but seed size varies with region of domestication (Sexton et al, 1997). Red colored kidney shaped and medium sized beans are preferred equally in all parts of the state while many farmers claim black colored bean seeds to be tasty and good for the stomach.…”

A total of 80 diverse germplasm accessions of common bean (Phaseolus vulgaris L.) were collected from 31 different locations known for marginal and risk prone farming systems in remote and hilly areas of North-Western Indian Himalayan state of Jammu and Kashmir. The variability was observed in seed color, shape, size and 100-seed weight. Thirteen colors of bean seeds were represented in these 80 accessions with high predominance of red colored seeds. Cuboid, kidney and oval seed shapes observed were represented respectively in 61.25%, 25% and 13.75% of the accessions. There were significant variations in seed length, width and 100-seed weight being highly significant in the later case. All the three seed size classes (small, medium and large according to CIAT categorization) were represented in the collected accessions. 22.5% accessions have 100-seed weight less than 25g, 53.75% accessions have 100-seed weight between 25-40g while 100-seed weight of more than 40g was recorded in 23.75% of the accessions. Highly positive correlations were found between 100-seed weight and seed length and width and between seed length and seed width. The 80 accessions were grouped in three clusters at a coefficient level of 0.3 with largest cluster of 59 accessions followed by a medium cluster with 20 accessions and the least with a single accession. Grid maps generated through DIVA-GIS software indicated that diverse accessions of common bean in terms of seed size and weight can be sourced from the areas falling in Budgam, Shopian and Kulgam districts of the state. Conservation of this remarkable genetic diversity is recommended for future propagation, breeding and the investigation of the genetic relationships.

Sing et al (1991a) reported that small-seeded (<25 g/ 100 seed) landraces are from the Mesoamerican Center, and large seeded from Andean (Sing et al, 1991a;Sexton et al, 1997). Rodino et al (2001) reported that Andean types include medium and large, white and pinto seeded cultivars.…”

“…Bean is a well-adapted crop and it shows a large variation through the Black Sea region (Bozoglu and Sozen, 2007). Seed color and seed shape of bean are the most prominent indicators of genetic variability and consumer habits but seed size varies with region of domestication in common bean (Sexton et al, 1997). Escribano et al (1997) informed that estimates of heritabilities of length/width and width/thickness ratio of dry seed were high on germplam of Northwestern Spain.…”

Artvin province located in northeast region of Turkey is small province but has rich plant diversity due to its different geographical and ecological formation. Significant part of this province has been flooded by the dams which have been built. The common bean is a very important crop for Artvin's farmers. This study was carried out with the aim of determining and preserving the characteristics of domestic bean varieties grown in Artvin. Common bean seeds were collected from 279 locations in 74 villages in seven districts of the province. These seeds were allocated to 400 sample groups according to their shapes and colors. Eleven monocolored and 21 dicolored or polycolored seed groups were determined. Majority of the seed were subcompressus type seeds. The samples in the 1st group were ranked first in terms of size index. Considering the 100 seed weight, 64.68% of the population was found between 25 to 40 g; 30.69% of the population was higher than 40 g. By the advantage of having big variation of all characters, landraces of bean varieties grown in Artvin Province have a rich genetic source that can be used in breeding programs.
