“…In this study, fifty-one germplasm of spinach were characterized morphologically based on thirteen (13) qualitative and (8) quantitative traits. Twenty-one ( 21) morphological traits including six (6) quantitative and fifteen (15) qualitative of 200 spinach accessions were recorded by [9]. Fifty-four spinach landraces collected from diverse geographical regions of Iran were evaluated for ten (10) qualitative and nine (9) quantitative characters [1].…”

“…The value of germplasm collection depends not only on the number of accessions but also on the genetic diversity present in those accessions. Diversity in the gene pool of a species may affect the adaptability to a new environment as well as to develop new varieties more tolerant to stress and pathogens [9]. Hence, characterization of the collected germplasm is essential for easy and rapid evaluation of germplasm.…”

Spinach, a leafy green vegetable cherished for its nutritional and medicinal benefits, is globally cultivated. This study assessed the genetic diversity of fifty-one Spinacia oleracea L. germplasms from diverse regions in Bangladesh, utilizing both qualitative and quantitative traits. Variation was observed across all traits, except for Inflorescence color and seed type. Leaf shapes included elliptic, broad elliptic, ovate, and broad ovate, with elliptic being predominant. Maximum variation was noted in edible leaf weight per plant, followed by petiole length and the number of lateral branches. Specific germplasms exhibited longer and broader leaves, with RC-139 having the highest number of lateral branches. Bolting time, with NQ-68 requiring the most days, proved to be a crucial trait for spinach. The dendrogram grouped thirty-six germplasms into Cluster I, while Cluster IV contained a solitary germplasm. Cluster II showed the highest mean values for leaf length, leaf width, and edible leaf weight per plant. Principal Component Analysis revealed that leaf length, leaf width, and petiole length were pivotal contributors to germplasm diversity. Selecting for leaf traits and bolting time, germplasms TRMR-136, TRMR-144, R-342, RNF-26, NQ-68, and RC-139 are recommended for future breeding programs based on their distinctive characteristics.

“…Morphological evaluations of leaf fragility indicated a low fragility level in 28%, medium in 35.6%, and high in 36.3% of 157 genotypes. Rashid et al (2020) conducted a field trial to investigate the genetic diversity of spinach germplasm from 30 different countries by using 21 agro-morphological features, six of which are quantitative and 15 of which are qualitative.…”

Ispanak (Spinacia oleracea L.), yenilebilir yeşil yapraklar için kullanılan en önemli kışlık sebzelerden biri olmakla birlikte dünyanın çoğu bölgesinde talep artışına bağlı olarak son on yılda üretim miktarlarında önemli değişiklikler meydana gelmiştir. Kullanıma bağlı olarak, ıspanak yaprakları genel olarak üç tipe ayrılır: (i) savoy tipi (taze pazar amaçlı kullanılır), (ii) işleme tipi (düz, kırışıksız ve kürek şeklindeki yaprakları olan pürüzsüz yaprak tipi), ve (iii) tadı ve narin yapısı nedeniyle tercihen salatalarda kullanılan bebek ıspanaktır. Ispanak popülasyonlarının araştırılması yeni çeşitlerin geliştirilmesi ve çalışmalarının başarıya ulaşabilmesi için ıspanak popülasyonları hakkında yeterli biyolojik, taksonomik, genetik ve agronomik bilgi birikimine gereksinim vardır. Bu araştırma ülkemiz koşullarında kışlık sebze olarak performanslarının belirlenmesi için yerli ve ticari çeşitlerden oluşan S2 kademesine ait 157 ıspanak genotipi agro-morfolojik özellikler kullanılarak çeşitliliklerini belirlemek için değerlendirilmiştir. Çalışılan genotipler, dünyadaki çekirdek ıspanak koleksiyonunun oluşturulması için önemli bir kaynaktır. Sonuç olarak IPGRI kriterlerine göre agro-morfolojik karakterizasyonu yapılan ıspanak genotiplerinin yüksek oranda morfolojik çeşitlilik gösterdiği göstermiştir. Mevcut araştırmanın sonuçları, ıspanak yetiştirme programlarında yerel türlerin korunması ve kullanılması görevlerini destekleyeceği düşünülmektedir.

“…To find morphological intraspecific relationship between 31 local accessions of Spinacia oleracea were split into two main clusters. Similarly, Rashid et al (2020) separated the east Asia spinach accessions into clusters to clear the morphological difference among them. At 48% genetic linkage distance group, cluster 1 was further divided into two sub clusters 1a and 1b.…”

Spinacia oleracea L. is an edible crop and considered as super food due to high nutrient values. Due to these properties the pot-based project was designed to explore the most diverse accession of this species, 31 local S. oleracea accessions were evaluated taxonomically on the basis of morphological and anatomical markers. Seeds were sown in clay pots to evaluate different morphological characters. The germination period varied from 6 to 15 days while variation in number of leaves was observed to be from 12 to 68 leaves per plant. Moreover, abaxial and adaxial epidermal leaf analysis was examined under light microscope to study the existing anatomical variations. Substantial variations were observed among quantitative characters including number of subsidiary cells (3-5 on both abaxial and adaxial sides), stomata number per unit area (6-21 on abaxial side; 8-18 on adaxial side) and stomatal index (13.9-28.6 on abaxial side; 14.8-25.5 on adaxial side). The shape of epidermal cells varied from tetragonal to pentagonal, hexagonal and irregular. The results concluded that leaf epidermal anatomical markers could be applied considerably in delimiting the species to solve the existing taxonomic problems among them. However, for more authentic results it would be preferred to use more taxonomic tools in integration with anatomy to study intraspecific variations.
