A total of 39 accessions of distinct types in less-known melons, C. melo subsp. agrestis var. agrestis (local names-‘choti kachri’, ‘badi kachri’, ‘sukkangai’), C. melo subsp. agrestis var. momordica (‘phunt’, ‘vellari’; snap melon), C. melo subsp. agrestis var. conomon (‘sohthiar’; oriental pickling melon), C. melo subsp. melo var. flexuosus (‘kakdi’, ‘tar’; snake melon) and C. melo subsp. agrestis var. alwarensis (‘arya’) were studied for morphological characters of fruit to identify their genetic resource value. Out of 39 accessions, four taxa were selected for nutritional analysis and the floral diversity study on the basis of research gaps, status of diversity in wild and vulnerability in cultivation, and non-availability of comparative account in the context of diversity in the Indian region. Nutritional components of 12 accessions of four taxa-‘choti kachri’ and ‘badi kachri’, snap melon, snake melon and ‘arya’ were analyzed. Additionally, the floral diversity traits were studied to support marker characters and to classify the subspecies under the respective botanical varieties and cultivar delimitation. Morphologically ‘choti kachri’ and ‘badi kachri’ were identical except for the fruit size and weight; arya and snake melon grouped together with snap melon and other intermediate forms; oriental pickling melon was entirely distinct, more closer to the musk melon but had no fruit aroma. Based on floral diversity study, ‘choti kachri’ and ‘badi kachri’ were grouped together whereas snake melon and ‘arya’ were closer and snap melon showed intermediary position. The result of the nutritional analysis clearly demonstrated variability recorded among accessions for all proximate traits in ‘choti kachri (IC629817) which had the highest proteins (2.16–3.67%), ash content (3.059%), crude fat (0.482%), dietary fibre (4.12%), starch content (3.50%), Fe (4.06 mg/100 g), Zn (1.498 mg/100 g), total phenols (29.5%) and ascorbic acid (25.9 mg/100 g) among the studied melon accessions. On the other hand, ‘badi kachri’ (IC629828) had the least protein, crude fat, Cu, Fe, total phenol and ascorbic acid contents followed by snap melon, snake melon and ‘arya’ with moderate to low values of all nutritive traits. The study would facilitate identification of the distinct morphotypes in each category and grouping the intermediate type and unknown taxa. Fruit nutritional analysis will help in using them for desirable nutritional traits for pre-breeding programmes. Besides, the floral diversity can lead to identification of marker characters in crop improvement programme.

It can serve as a potential source of resistance for ToLCNDV that can be imparted to other melons. Unlike other melons, Arya melons can be successfully grown both during spring summer and rainy (kharif) season. Arya IC629818-A bear long and good number of fruits per plant (8-10), thus can serve as a substitute to long melon during kharif season. Moreover, IC629823 and IC629818B had long cream coloured fruit which make them unique and attractive to the consumers.

Data were recorded on 32 descriptor traits (both qualitative and quantitative) using the minimal descriptors developed by the ICAR-National Bureau of Plant Genetic Resources, with minor modifications. Analysis of the data was carried out using Ward’s Minimum Variance method and categorized into seven major clusters. PCA analysis revealed that the first six principal components (Eigen value greater than 1), are contributing 72.33% of the total variance which were mostly influenced by mature leaf length, leaf width, leaf petiole length, plant height, seed length, seed width, days to flower initiation, essential oil percentage, seed length/width ratio, leaf length/width ratio, number of primary branches and fresh herbage yield. All the accessions showed high degree of varia...

These accessions were evaluated in an augmented block design for two years for nine yield attributing traits and analysis of variance, path analysis, correlation and hierarchical cluster analysis was performed on the recorded data to estimate the extent of variability among genotypes and to measure the direct and indirect contribution of different yield attributing traits on yield. Significant genetic variability was observed among the accessions for all the studied traits with high estimates of heritability and genetic advance. Highly significant and positive correlation was found between different traits and yield per plant. The hierarchical cluster analysis grouped the genotypes into 11 distinct non-overlapping clusters. It was concluded that the genotypes possess significant variability enabling them as candidate genotypes to be utilized as parents for breeding of pigeonpea varieties with desired attributes.
