Abstract

Abstract: Main parameters and methods of chromosome preparing wi th wall degradation hypotonic technique in cucumber were s tudied, and a sui table method was es tablished.The resul ts indicated that there was a evident correlationship between chromocenter diameter, heterochromatin number and plant ploidy level.The chromocenter diameter and heterochromatin number of haploid and double haploid are 5.1, 5.0μm and 13.3, 11.9μm respectively.

Key words: Cucumber, Chromosome, Ploidy, Appraisal, Section cutting
