Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When scientists combine different plants in an attempt to grow a plant with the best traits from both parents, the new plant is called a(an):
A
Hybrid
B
Clone
C
Variation
D
Pistil
Explanation: 

Detailed explanation-1: -In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction.

Detailed explanation-2: -A hybrid plant is the result of cross pollinating two different plant varieties and growing the seed the mix produces. The plant that grows from that seed combination is called a hybrid. Commercial cross planting is done to get some type of valued attribute of each initial variety into the offspring.

Detailed explanation-3: -Interspecific hybridization has been and still is one of the useful methods for plant breeders to create new plant forms or to introduce genes from related wild species into crops of interest.

Detailed explanation-4: -Heterosis. It has long been observed that crossing two plant species or genotypes can create a hybrid with faster growth rate, more biomass at maturity, and/or greater reproductive output than its parents. This counterintuitive phenomenon is called hybrid vigor or heterosis.

Detailed explanation-5: -Definition: In breeding, hybrids are plants or animals produced by the cross-breeding of two genetically different varieties or species. Source: GreenFacts. More: Plant hybrids are created when the pollen from one kind of plant is used to pollinate an entirely different variety, resulting in a new plant altogether.
