“…This technique has advantage such as low development cost, low level of training and low cost for assay (Karp et al, 1997). RAPD markers have been used to assess genetic diversity among the species of sesame (Bhat et al, 1999;Ercan et al, 2004;Pham et al, 2009), bitter gourd (Dey et al, 2006), spine gourd (Rasul et al, 2007), ash gourd (Sureja et al, 2006), pumpkin (Gwanama et al, 2000), gac (Bootprom et al, 2012;Wimalasiri et al, 2016). The purpose of this study was to evaluate genetic diversity of gac accessions collected from Mekong delta of Vietnam by using RAPD markers.…”

Gac (Momordica cochinchinensis (Lour.) Spreng) (2n = 28) belongs to the Cucurbitaceae family. It is indigenous throughout in Vietnam as well as in South East Asia. To estimate the genetic diversity, 20 gac accessions collected in Mekong river delta were analyzed using 10 RAPD primers. Total of 126 fragments were obtained from ten RAPD primers, with 114 polymorphic fragments, and average of 11.4 fragments per primer. The high level of polymorphism (90.4%) was found across 20 gac accessions. The high est Nei's gene diversity value among gac accessions was H = 0.40, and the lowest was H = 0.29 with a mean of 0.36. The highest Shannon diversity index value among gac accessions was H' = 0.58 and the lowest was H' = 0.46 with an average of 0.53. Cluster analysis for genetic relationship between accessions displayed that 20 gac accessions grouped into four main clusters which genetic distance coefficient ranged from 0.29 to 0.64 and with an average of 0.54. There were defined groups according to their locations. According to these results, RAPD technique can be useful tool in genetic diversity evaluation of gac. The information achieved could also be useful for gac breeding program, cultivar differentiation and conservation.

“…Despite what Peter et al (1991) claimed about low diversity of the ash gourd gene pool, Pandey et al (2008) reported that in a study based on molecular markers quite big diversity of the ash gourd germplasm was detected; on the other hand, Sureja et al (2006) reported small diversity of the ash gourd germplasm they studied. The diversity of physiological and crop traits in our research was very large (see Fig.…”

Searching for the optimum multivariate profile of an ash gourd [Benincasa hispida (Thunb.) Cogn.] genotype

Ash gourd is an important vegetable especially in the Indo-China region, but also in America and Africa. It is a monotypic genus, and its genetic pool is considered little diverse, which makes breeding of good ash gourd cultivars difficult. A pool of 56 genotypes, of which 10 are released cultivars and 46 indigenous lines collected from different parts of India, was studied in a two-year experiment. Various traits are important when breeding new cultivars, so an optimum multivariate performance is studied in this germplasm, with a special focus on traits of the greatest importance, namely fruit yield per plant, flesh thickness, vine length, and number of days to female and male flowering. Such performance is studied for the bestyielding genotypes, and promising genotypes in terms of multivariate performance are selected.

“…Earlier, molecular markers like RAPD have been used to assess genetic diversity among the species of bitter gourd (Dey et al 2006), spine gourd (Rasul et al 2007), cucumber (Horejsi and Staub 1999), pumpkin (Gwanama et al 2000), watermelon (Lee et al 1996) and ash gourd (Sureja et al 2006). Besides, ISSR markers have been employed in genetic diversity analysis of different cucurbits (Dje et al 2006;Levi et al 2004;Ritschel et al 2004) and in phenetic studies among related Momordica species namely, Citrullus, Cucumis and Praecitrullus fistulosus (Levi et al 2005).…”

Twenty-one RAPD and twelve ISSR primers were used for assessment of genetic diversity and establishing phenetic relationships among 35 genotypes of six currently cultivated Indian Momordica species and five genotypes of two Luffa species. A total of 436 RAPD and 230 ISSR scorable fragments were produced of which 99.8% fragments showed polymorphism among the species and varieties of Momordica and Luffa. The level of polymorphism detected by the 33 random primers was higher among the species (99.8%) of Momordica than that estimated among the varieties (61.3%). The varieties belonging to dioecious Momordica species (75.6%) showed a higher level of polymorphism as compared to monoecious species (50.3%). A significant level (68.6%) of polymorphism however was detected by the two marker types among the Indian varieties of monoecious M. charantia species. A wider range of molecular diversity (16-95%) detected by both RAPD and ISSR markers reflected presence of high level of genetic variation among the species and Indian varieties of Momordica and Luffa. The level of inter-specific diversity was maximum (90%) between annual monoecious M. charantia and perennial dioecious M. cochinchinensis whereas the extent of intra-specific diversity was highest particularly in dioecious species (51%) as compared to monoecious species like M. charantia (38%). Wider divergence of the taxon of controversial identity, M. cymbalaria from the other Indian cultivated Momordica species and their evolutionary closeness with Luffa species was evident. The clustering pattern obtained among the 40 genotypes belonging to different Momordica and Luffa species corresponded well with their morphological, cytological and taxonomic classification, which was further supported by high boot-strap values and PCA analysis. Species and genotype-specific fragments detected by the random markers would be useful in introgression breeding for genetic improvement of Momordica cultivated in India. A smaller set of 28 informative random markers screened in this study could precisely differentiate the Momordica genotypes from each other and thus would be of use in many marker-based genotyping applications in Momordica.
