Screening of Bitter Gourd Hybrid Combinations with High Yield and Disease Resistance

[Objectives]This study was conducted to breed and promote high-yield and disease-resistant varieties of bitter gourd.[Methods]The comparison experiments of six new hybrid combinations(Z1705,Z1706,Z1717,Z1721,Z1732,Z1745)were successively carried out at two experimental sites of Danzhou and Tunchang.[Results]Comparing the agronomic traits and disease resistance of various combinations,it was concluded that Z1717 and Z1721 have high yields,green and glossy fruit surface and good comprehensive disease resistance,so they can be popularized and planted.[Conclusions]This study is of great significance for improving the yield of bitter gourd and increasing economic benefits.
