However, people hoped that it would grow larger and more fragrant flesh than seeds, so this also became the breeding direction of scientists. During the breeding process, scientists will eliminate individuals with more seeds, leaving those with larger flesh, and continue to hybridize to purify genes. 2. Not nowIn modern times, after continuous hybridization, genetic purification has been completed and the seedless banana was born. However, if it is cross-bred with other varieties of bananas, its genes may be "contaminated", so asexual reproduction that does not change the genotype is currently used for banana cultivation. |
