Detailed explanation-1: -To increase the crop yield. To raise plants with desired characteristics. To develop a disease-resistant crop. To develop plants that can tolerate extreme environmental stress.
Detailed explanation-2: -The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.
Detailed explanation-3: -The object of hybridization is to combine desirable genes found in two or more different varieties and to produce pure-breeding progeny superior in many respects to the parental types.
Detailed explanation-4: -The chief objective of hybridization is to create variation. When two genotypically different plants are crossed, the genes from both the parents are brought together in Fl. Segregation and recombination produce many new gene combinations in F2 and subsequent generations.
