Abstract

The objective of this study was to assess the diversity of soft pear germplasm in the Jammu region and identify exceptional soft pear genotypes with superior characteristics. A total of sixty soft pear genotypes were gathered from diverse locations within the Jammu region, and an extensive examination of their distinct morphological characteristics was conducted. The pear genotypes exhibited significant variation in terms of leaf characteristics. A collection of 60 pear accessions was assembled from various locations in the Jammu district, and their diverse morphological traits were thoroughly examined. The studied genotypes demonstrated diversity concerning leaf characteristics. The findings revealed a substantial variation in the following leaf parameters: leaf length ranging from 4.38 cm to 9.00 cm, leaf breadth spanning from 2.00 cm to 5.33 cm, leaf shape index varying between 1.02 cm and 3.41 cm, leaf area ranging from 13.66 cm to 40.35 cm, and petiole length varying from 1.00 cm to 4.16 cm. Pear cultivars often have a narrower genetic base due to the selection and propagation of a limited number of commercially desirable traits. This can result in reduced adaptability, susceptibility to diseases, and limited potential for future breeding improvements. The findings indicated that the observed variations in these traits could be attributed to the genotypes present or the prevailing environmental conditions in the cultivation regions, or a combination of both these factors. The observed variation in leaf characteristics indicates the presence of a diverse range of traits among the studied genotypes, which holds promising potential for future enhancement programs. This variability can be harnessed for the development and improvement of pear cultivars.

Conclusion

The objective of our research was to acquire a wide range of soft pear varieties, and our investigation has substantiated the existence of a substantial diversity of soft pear in the North Western Himalayan region. Consequently, it has become imperative to safeguard these distinctive genetic resources in order to enhance morphological quality parameters. Moreover, in order to guarantee their preservation, exchange, and utilization in forthcoming breeding programs, as well as to foster the development of innovative, market-oriented cultivars through the implementation of efficient genetic methodologies, further exploration is indispensable.
