“…The average length of petals among accessions was 2.99 mm in Ms12 from M. spicata up to 5.23 mm in Ma24 from M. aquatica (Table 4). Hoque et al (2014) reported that the petal length ranged from 3 to 3.5 mm which has overlap with the data reported here. The phenotypic and genetic variation coefficients for this trait were 11.33 and 11.3%, respectively.…”

“…Petal color in Ms20 and Ms12 from M. spicata was white, in Ml30 and Ml29 both from M. longifolia, Ms22 from M. spicata and Ma24 from M. aquatica was violet, and was dark violet in Ml28 from M. longifolia. Hoque et al (2014) in the study of morphological traits in some germplasm of mint reported that the color of open flower was white and purple. Vining et al (2019) in genetic diversity survey of M. aquatica demonstrated that M. aquatica corollas were purple.…”

Mentha is one of the most important genera of the Lamiaceae with a wide geographical distribution and considerable commercial importance. The general aim of this work was to group 34 accessions from four species of mint using ISSR molecular markers to select some accessions to estimate the potential cross-ability of mints valuable in breeding and phytochemical research. The reproductive characteristics including the type of flower, petal color, sepal and petal lengths, length of stamen and pistil as well as the number of free and living pollen grains in the anther were also studied to find out cross-ability patterns and the possible reproductive barriers. Analysis of molecular variance (AMOVA) among and within species showed more intra-specific variation (92.24%) in comparison with inter-species variation (7.76%). Results of cluster analysis based on ISSR data grouped the mint genotypes into five clusters. By this, the greatest genetic similarity was found between Ms12 from M. spicata and Ml29 from M. longifolia. The genotype Ms12 along with Ms22, the other genotype from M. spicata, were found to be male sterile due to stopped stamen development. These two had higher combining ability (seed set) when used as the female parent in intra-specific crosses and when crossed with M. longifolia compared to the other genotypes in diallel crosses. The highest number of hybrid seeds was obtained where Ml29 was crossed as the male parent with male sterile Ms12 as the female one. This high success rate of seed set in interspecific crosses between M. spicata and M. longifolia could be related to their genomic similarity confirmed by ISSR molecular data. Therefore, producing hybrid seeds and subsequent generations from crosses between these species, utilizing male sterility mechanism, can be a source of new genetic variation for mint.

“…Over the last couple of decades, there have been numerous phylogenetic studies of the genus Mentha, mostly of the section Mentha, using morphological, cytological and chemical characters (e.g., [59,62,63,[80][81][82][83][84][85][86][87][88][89][90][91]) as well as molecular markers (e.g., [55,60,61,64,66,[92][93][94][95][96][97][98][99][100][101][102][103][104][105]). However, despite the enormous amount of data gathered, the classic taxonomic divisions (e.g., [22,106]) still largely stand.…”

The genus Mentha is taxonomically and phylogenetically challenging due to complex genomes, polyploidization and an extensive historical nomenclature, potentially hiding cryptic taxa. A straightforward interpretation of phylogenetic relationships within the section Mentha is further hindered by dominant but outdated concepts on historically identified hybrid taxa. Mentha spicata is traditionally considered to be of hybrid origin, but the evidence for this is weak. Here, we aim to understand the phylogenetic relationships within the section Mentha using large sample sizes and to revisit the hybrid status and identity of M. spicata. We show that two of three traditional species in the subsection Spicatae are polyphyletic, as is the subsection as a whole, while the real number of cryptic species was underestimated. Compared to previous studies we present a fundamentally different phylogeny, with a basal split between M. spicata s.s. and M. longifolia s.s. Cluster analyses of morphological and genotypic data demonstrate that there is a dissociation between morphologically and genotypically defined groups of samples. We did not find any evidence that M. spicata is of hybrid origin, and we conclude its taxonomic status should be revised. The combination of genetic and phenotypic information is essential when evaluating hyperdiverse taxonomic groups.

“…This result was in agreement with the findings of Hossain et al (2011), who found number of leaf ranged from 8.50-12.25. Hoque et al (2019) found that number of leaf was varied significantly ranges from 11.7-8.0. Wide variation in leaf length amongst some genotypes of gladiolus was observed by Singh, and Dadlani (1990).…”

The study was conducted at the research field of Nalitabari Sub-station, BINA, Sherpur during the period November 2019 to May 2020 to characterize, evaluate and select promising gladiolus varieties suitable for Bangladesh and to determine the optimum dose of radiation for LD50 for varietal improvement. The parameters studies were plant height, days to 1st flowering, number of leaves per plant, leaf length, leaf breadth, length of spike, length of rachis, number of flower per spike, flower diameter, number of corms per plant, weight of single corm, vase life, per cent germination, per cent survivability, shoot length and root length. The longest plant (154.2 cm) was observed in White Prosperity, while the shortest plant (101.7 cm) was in Regency. The longest leaf (70.3 cm) was found in Red Cascade and the shortest leaf (48.0 cm) was found in Her Majesty. The highest number of floret per spike was produced by Red Cascade (17.3) followed by White Prosperity (17.0). The Regency produced the lowest number (8.0) of floret per spike. The longest vase life (9.3 days) was observed in American Beauty followed by (8.7 days) Red Cascade, while the shortest vase life (5.7 days) was recorded in Wine and Roses. In radio sensitivity test, 30-40 Gy of gamma irradiation would be the optimal dose for inducing useful mutation in gladiolus. Bangladesh J. Nuclear Agric, 37(2): 43-56, 2023
