Current Status of Breeding and Protection of Luffa Varieties and DUS Testing in China
In the current pursuit of new quality productive forces,the full exploration of excellent germplasm resources and the continuous strengthening of variety distinctness,uniformity and stability(DUS)testing execution and industry influence were crucial for the development of the Luffa industry in China.This article reviewed the research status of collection,conservation,and evaluation of Luffa germplasm resources in China over the past 20 years,along with the progress on variety breeding focused on goals such as early maturity,disease resistance,cold and heat tolerance,high yield and quality,and analyzed the current status of variety protection;Meanwhile,it analyzed the traits composition and observation and measurement methods outlined in the DUS testing guidelines,summarized the application of approximate variety screening,seed germination,trait observation,and distinctness judgment in the DUS testing of Luffa,and furthermore,pointed out issues in testing level,standard varieties,and trait expression status during the DUS testing.It further proposed development strategies for innovative breeding of new varieties of Luffa,which could comprehensively apply modern breeding technologies to meet the industrial needs of diversified breeding goals,and timely initiate the revision of DUS testing guidelines,in order to promote the high-quality development of the Luffa industry.
