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.

Why hybrids are adopted by farmers?
Greater productivity
Longer harvest duration
Better adaptability to variable environments
Better tolerance to diseases and pests
Uniform produce
Better market acceptability
Better nutritional quality6

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

Interspecies hybridization

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

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