5. Hybridization
5
Hybridization is the process of forming a hybrid or
number of hybrids by crossing between two
genetically dissimilar homozygous parents for the
betterment for human being.

6. Greater productivity
Longer harvest duration
Better adaptability to variable environments
Better tolerance to diseases and pests
Uniform produce
Better market acceptability
Better nutritional quality

8. Hybridization Technique
The most commonly utilized mechanisms
for developing commercial cucurbitaceous
crops is interspecies hybridization

10. Interspecies hybridization
Crossing between two species belonging to the
same genus.
Cucumis hardwickii × Cucumis trigonus
Cucumis melo

12. Limitations Interspecies hybridization
• Time consuming
• Labour intensive (Skill is necessary for
commercial seed production)
• Increased cost of production
