Seed size and shape analysis of registered common bean (Phaseolus vulgaris L.) cultivars in Turkey using digital photography

Abstract

In this study, the size and shape properties of twelve different bean cultivars (eleven varieties and a genotype) were determined using image processing method on digital photography and the cultivars were grouped depending on their properties. The highest mean values of geometric diameter, projected area, length, width and shape factor in the study were determined in the 'Çayırlı' genotype. 'Terzibaba' cultivar, more spherical shape at width orientation compared to other cultivars, had the lowest value of thickness (4.6 mm) and more circular at the width orientation among the cultivars. The highest mean of thickness (6.0 mm) were measured in 'Elkoca-05' and 'Noyanbey-98' cultivars. The sphericity mean of 'Karacaşehir-90' (70%) was found higher than those of the other cultivars, while the geometric mean diameter, projected area, length and width values had the lowest mean. 'Yunus-90' and 'Göynük-98' cultivars had the lowest sphericity mean values of 58.9% and 58.7%, respectively. According to the results of Principal Component Analysis (PCA), the most important variables of the first component were mass, geometric mean diameter, surface area, volume, projected area, equivalent diameter, perimeter and length. According to the physical properties of bean cultivars 'Aras-98', 'Elkoca-05', 'Göynük-98', 'Noyanbey-98', 'Yakutiye-98' and 'Yunus-90' were oblongus; 'Karacaşehir-90' and 'Önceler-98' were ellipticus; 'Akman-98', 'Kantar-05' and 'Terzibaba' were subcompressus and 'Çayırlı' genotype was compressus. The size and shape features of the bean cultivars are considerably crucial parameters in terms of designing the seed metering mechanism of seed drills, and transportation, separating and sizing systems. So, the size and shape data of bean cultivars are of mostly importance to engineers, machine manufacturers and machine designers.

Morphological Seed Characterization of Common (Phaseolus vulgarisL.) and Runner (Phaseolus coccineusL.) Bean Germplasm: A Slovenian Gene Bank Example

“…The minimum and maximum values ranged between 8.06 and 19.98 mm for L, 4.24 and 9.56 mm for T, and 5.06 and 12.63 mm for W. For characteristic 100 seed weight the mean value of all 953 accessions was 51.13 ± 13.84 g, while the minimum and maximum values ranged between 19.32 and 98.39 g. The highest coefficient of variation was calculated for the 100 seed weight (27.06%) and the lowest for W/T (12.64%). As discussed by Rana et al [22] for 4274 common bean accessions conserved in Indian gene bank, L ranged 5.0–20.3 mm, W 2.0–12.0 mm and 100 seed weight 3.5–96.3 g. Similarly, Kara et al [23] reported for 12 registered Turkish common bean genotypes L 9.1–17.8 mm, W 5.8–10.0 mm, T 4.6–6.0 mm and 100 seed weight 18.0–65.6 g. As discussed by Giurcă [24] for 9 common beans originating from northern Romania and western Ukraine, L ranged 11.8–18.0 mm, W 7.4–9.7 mm, T 4.4–6.9 mm and 100 seed weight 34.3–54.2 g. Logozzo et al [4] evaluated 533 accessions of the European common bean germplasm and reported accessions with L 12.0–13.9 mm (35.5%), W 7.1–8.0 mm (33.0%) and T 5.0–5.9 mm (37.1%) were the most frequent.…”

Chemical and Physical Characterization of Common Bean (Phaseolus Vulgaris L.) Landraces by North – North-Western Extremity of Romania

“…The minimum and maximum values ranged between 10.01 and 19.5 mm for L, and 6.07 and 12.95 mm for W. For characteristic1,000 seed weight the mean value of all 28 accessions was 521.34 ± 208.19 g, while the minimum and maximum values ranged between 136.96 and 1,045 g. The highest coefficient of variation was calculated for the 1,000 seed weight (39.9%) and the lowest for L/W (13.2%). As discussed by Rana et al [20] for 4,274 common bean accessions conserved in Indian gene bank, L ranged 5.0 -20.3 mm, W 2.0 -12.0 mm and 100 seed weight 3.5 -96.3 g. Similarly, Kara et al [21] reported for 12 registered Turkish common bean accessions genotypes L 9.1 -17.8 mm, W 5.8 -10.0 mm, T (seed thickness) 4.6 -6.0 mm and 100 seed weight 18.0 -65.6 g. As discussed by Giurcă [22] for 9 common beans accessions originating from northern Romania and western Ukraine, L ranged 11.8 -18.0 mm, W 7.4 -9.7 mm, T (seed thickness) 4.4 -6.9 mm and 100 seed weight 34.3 -54.2 g.

As discussed by Sinkovič et al [16] for 953 common bean accessions conserved in Slovene gene bank at the Agricultural Institute of Slovenia, being part of the National plant gene bank, L (range 7.3 -27.2 mm); T (range 4.2 -11.0 mm); W (range 0.3 -16.5 mm); L/W (range 0.4 -2.6 mm); W/T (range 0.6 -2.2 mm); and 100 for common (range 19.3 -98.4 mm) bean seed weight.…”

“…Assim, características que nunca foram mensuradas antes ou somente em situações específicas estão começando a ser medidas com maior frequência e de maneira fácil como as características relacionadas ao tamanho, cor, forma e textura da semente (FIORANI; SCHURR, 2013). A análise digital de imagem de sementes vem sendo utilizada para a identificação de cultivares, determinação de sementes de diferentes cores, danos mecânicos e de classificação de diferentes tamanhos de sementes (VENORA et al, 2009;KARA et al, 2013;PINTO et al, 2015;ANDRADE et al, 2016).…”
