Wild apricot (Prunus armeniaca L.) is an economically important fruit crop for folk and marginal farmers and local tribal populations in the high-altitude difficult terrains of north-western Himalayas in Jammu and Kashmir and Himachal Pradesh states of India. This is a multi-purpose fruit tree species which, besides its fresh edible fruits, is preserved for use in diverse ways depending upon the type of cultivar. Seed kernel of apricot is used as edible nut and for the production of edible oil. In the present study, 147 diverse accessions of wild and cultivated apricot belonging to 28 folk cultivars were collected and characterized for fruit, stone and kernel characters. Indigenous traditional uses and importance of fruits and kernels of these folk cultivars have been recorded and described. Promising table-type cultivars identified were Margulam, Lodi, Shakarpara, Narmo and Khurmani, while drying-type cultivars were Halman, Shakarpara, Rakchey Karpo and Tachu. Cultivars Chuli and Shadi were the most common types and widely distributed with vast variability, while other cultivars had localized presence. Some of these folk cultivars have high potential for promotion as commercial cultivars of apricot in this high-altitude area basically depending upon traditional production system. Genetic resource management including collection, characterization and documentation of existing variability of apricot is of immense importance for safe conservation and commercialization of potential cultivars to enhance farmer's livelihood in this fragile agroecosystem.

Apricot (Prunus armeniaca L.) is an important temperate fruit crop worldwide. The availability of wild apricot germplasm and its characterization through genomic studies can guide us towards its conservation, increasing productivity and nutritional composition. Therefore, in this study, we carried out the genomic characterization of 50 phenotypically variable accessions by using SSR markers in the erstwhile States of Jammu and Kashmir to reveal genetic variability among accessions and their genetic associations. The genetic parameter results revealed that the number of alleles per locus (Na) ranged from 1 to 6 with a mean Na value of 3.89 and the mean effective number of alleles (Ne) per locus 1.882 with a range of 1.22 to 2. Similarly, the polymorphic information content (PIC) values ranged from 0.464 to 0.104. The observed heterozygosity (Ho) (0.547) was found to have higher than expected heterozygosity (He) (0.453) with average heterozygosity of 0.4483. The dendrogram clustered genotypes into three main clades based on their pedigree. The population structure revealed IV sub-populations with all admixtures except the III sub-population, which was mainly formed of exotic cultivars. The average expected heterozygosity (He) and population differentiation within four sub-populations was 1.78 and 0.04, respectively, and explained 95.0% of the total genetic variance in the population. The results revealed that the SSR marker studies could easily decrypt the genetic variability present within the germplasm, which may form the base for the establishment of good gene banks by reducing redundancy of germplasm, selection of parents for any breeding program.

Genetic diversity of seventeen chickpea genotypes was studied through Mahalanobis D2, Tocher’s Method. The genotypes under study fall into five clusters. The cluster- IInd contained the highest number of genotypes (08) and Cluster IV and V contained the lowest (01). Cluster- II produced the highest mean value for days to maturity. The inter-cluster distances were much higher than the intra-cluster distances. Cluster-V exhibited the highest intra-cluster distance while the lowest distance was observed in cluster-IV and V. The highest inter-cluster distance was observed between cluster-III and V while the lowest was between cluster-I and IV. Considering all the characters, it is suggested that the genotypes 81-0-800, C-306, 96907, C-235 and SCS-3 could be used as parents for future breeding programmes to develop high yielding varieties of chickpea. As per AMMI model, two genotypes i.e. C-81 and 96911 were identified as having wider adaptability along with higher seed yield per plant.

The present communication deals with three butterfly species belonging to family Lycaenidae and subfamily Theclinae, recorded for the first time from different localities in a mountainous watershed in the Union Territory of Jammu and Kashmir during 2020. These include Esakiozephyrus icana, Spindasis ictis and Tajuria jehana. The information on their current extent and known occurrence will be helpful in updating the range distribution of butterflies in north-western Himalayas.

The present communication deals with eight species of Hesperiidae recorded for the first time from different localities in the Union Territory of Jammu and Kashmir during 2018 to 2020. These include Burara oedipodea belesis, Matapa aria, Erionota torus, Udaspes folus, Coladenia indrani indrani, Tagiades cohaerens cynthia, Celaenorrhinus dhanada and Pseudocoladenia fatih. The information on the current extant and their known distribution till now has been given along with the photographs. These records will be helpful in updating the range distribution of butterflies in north western Himalayas.
