(L.) Roem. is an important cucurbit crop that assures food security and dietary diversity among the poor communities.

The hermaphrodite form of Luffa acutangula (known as Satputia) is an underutilized vegetable with a unique clustered fruiting habit. Its desirable traits, such as plant architecture, earliness, as well as contrasting traits like unique clustered fruiting, bisexual flower, and crossability with Luffa acutangula (monoecious ridge gourd with solitary fruits), make it a potential source for trait improvement and mapping of desirable traits in Luffa.

This emphasized the need for an investigation to search for the possible occurrence of the other related species In this view, different cucurbit hosts exhibiting severe chlorosis, bleaching, and yellowing symptoms were collected from the Vegetable Experimental Fields of IARI, New Delhi. The samples exhibiting yellowing and bleaching symptoms were associated with small isometric virions measuring ~ 25 nm under transmission electron microscope.

The characterization of the diversity pattern of Indian bottle gourd accessions will facilitate the optimal use of genetic resources for breeding improved cultivars.
Methods: In the present study, the magnitude of genetic diversity was evaluated in ninety-one genotypes of bottle gourd collected across fourteen different agro-climatic zones of India.
Investigation of genetic diversity is essential for the selection of parents for crop breeding and conservation of genetic resources. To estimate the genetic variability and population structure in the midst of 45 accessions of sponge gourd brought together from different geographical areas of India, morphological traits and two molecular markers, ISSR and SCoT markers were compared. Principal components analysis of 20 morphological traits showed 72.
