Abstract：To address key challnges in summer-autumn silkworm rearing—such as high disease incidence，poor cocoon silk quality，and labor shortages in pupae identification for seed production—a comparative field trial was conducted in Shiquan County，Shaanxi Province，during the summer and autumn of 2O22.The study evaluated four silkworm varieties： Shaohui × Xudong， Jinxiu × Xiaoxiang， Jingsong × Haoyue， and Liangguang No.2.Non-parametric statistical methods，stability indices，and related parameters were used to assesskey performance traits reflecting yield stability and production potential.These traits included cocoon yield per rearing unit，healthy pupation rate，filament length，reelability，reelable silk length，andraw silk cleanliness.Additional analysis focused onthe breeding performance and seed production cost of the introduced variety Jinxiu × Xiaoxiang. The results indicated that Jinxiu × Xiaoxiang exhibited strong vitality，was easy to manage，produced largecocoons，and had superior silk quality，along with high yield potential and good stability.It showed good adaptability to the sericultural conditions of southern Shaanxi，fulfilling the production requirements of the regional silk industry.Moreover，its excellnt breeding traits significantly reducedseed production costs. Asasex-limited mottled strain，it also alleviated labor demands for pupae identification，making it highly favored by silkworm farmers，silk-processing enterprises，and seed producers.The variety exhibited distinct characteristics and holds strong potential for widespread adoption.
