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

ProcessRemove male flower

Late male floweringUse chemical (250ppm Ethophenol)Introduce of female plant

Limitations Interspecies hybridization

• Time consuming

• Labour intensive (Skill is necessary for commercial seed production)

• Increased cost of production
