Abstract
Plant breeders exploit heterosis to produce high-yielding crop varieties over their pure line parents; however, genetic segregation in the advanced generations leads to losing economic traits. Therefore, clonal propagation through matured seeds would be good enough to self-propagate the F1 hybrids. This approach would be rewarding to the farming community as they will not be forced to purchase fresh F1 hybrids seeds every year as they can use their farm seeds for the next season.
