In the present study, we compared our previously identified elite walnut selection JWSP06 (Parbat) with other walnut selections from the region. Based on DUS (distinctiveness, uniformity, and stability) characterization, Parbat is high yielding late maturing selection with superior quality nut and kernel traits. This selection is also resistant to walnut anthracnose. Recently the Parbat was notified as an elite walnut selection by the Government of Jammu and Kashmir. DNA profiling authenticate that “Parbat” is distinct from regional walnut selections such as Hamdan, Sulaiman, and Bhushan. The comparative study revealed that the quality and yield capacity of the Parbat are higher than those of local walnut selections. Regardless of the walnut selection, the marker WSSR-8 efficiently separates all genotypes. Breeding walnuts through conventional methods require genetically distinct parents. Our comparative study has identified Parbat as distinct from regional selections. This study has opened a door to breed quality walnut cultivars by crossing Parbat with Sulaiman and Hamdan. Being located at different geographic areas, the walnut selections need to be planted side by side for an effective hybridization-based breeding program.

在本研究中，我们将之前鉴定的优质核桃品种 JWSP06 (Parbat) 与该地区的其他核桃品种进行了比较。基于 DUS（独特性、均匀性和稳定性）表征，Parbat 是高产晚熟品种，具有优质坚果和籽粒特性。该选种对核桃炭疽病也有抗性。最近，帕尔巴特峰被查谟和克什米尔政府通知为精选核桃。DNA 分析证实“帕尔巴特”与区域核桃品种（如 Hamdan、Sulaiman 和 Bhushan）不同。比较研究表明，帕尔巴特核桃的品质和产量高于当地选育的核桃。无论核桃选择如何，标记 WSSR-8 都能有效分离所有基因型。通过传统方法培育核桃需要遗传上不同的亲本。我们的比较研究已将帕尔巴特峰与区域选择区分开来。这项研究为通过帕尔巴特与苏莱曼和哈姆丹杂交培育优质核桃品种打开了大门。由于位于不同的地理区域，核桃选育需要并排种植，以实现有效的基于杂交的育种计划。
