AbstractThis studysummarized thebreeding process，characteristics，and high yield cultivation techniquesof a peppervariety Hualuo 305.Developed through hybridization，multi-generational selection，and systematic identification，the variety wasbred with 23XZ494 as the female parent and 21XZ493 as the male parent.In terms of agronomic traits，its total growth periodwas17Odays，withaplant heightof70cmandaplantspreadof62cm，and each plant producedapproximately22 fruits.The fruits exhibited a full spiral shape with dense wrinkles，measuring 26-28 cmin longitudinal diameter，about 4.O cm in transverse diameter，and 55 b in single fruit weight， characterized by thin skin，crisp texture，and moderate pungency. Nutritionally， it contained 76.6 mg/100 g of vitamin C and 0.10% of capsaicin.In terms of stressresistance，the variety showed strong drought tolerance and tolerance to low temperature and weak light; regarding disease resistance，it was resistant （R）to cucumber mosaic virus （CMV）and tobacco mosaic virus （TMV）. In regional trials，Hualuo 305 outyielded the control variety 37-94 by 9.5 % -12.2%; in the 2024 production demonstration，the average yield reached2 664.9 kg/667 m2.The keycultivation techniques of Hualuo 3O5 were as follows： for early spring greenhouse planting， the density was 2 80o-3 2OO plants per 667 m2 with a seedling age of 60- （204 70 days;for autumn-delayed grenhouseplanting，the densitywas 32OO-3 6OO plants per 667m² with a seedling age of （2号 35-40 days.This cultivar exhibited weak heat tolerance，and temperatures above 35 ΔC inhibited its growth;it was susceptibletobacterial wiltinacidicsoils.Therefore，targetedregulationoffieldtemperature wasrequired，and150kg of quicklime per 667m2 was applied for soil improvement. This study provided a reference for the popularization and application of Hualuo 305.
