In most of fruit crops, seed propagation has not been successful because of heterozygosity of seeds, minute seed size, presence of reduced endosperm, low germination rate, and also some are having seedless varieties.
Consequently, S-genotyping is also useful in the elucidation of crop evolution and propagation history of a given species.
But once coconut became a commercial crop the nursery propagation methods became economically important and the various techniques to improve germination success, previously mentioned, were applied piecemeal.
The determination of the S-alleles in local Moroccan apricots has also allowed elucidating and confirming some aspects of crop evolution and propagation history of apricot in the Mediterranean Basin.
In passage rites the king often was the principal actor in the promotion of the growth of the crops and the propagation of man and beast and in the promotion of the reproductive forces in nature in general at the turn of the year.
This technology is widely employed in horticultural crops for vegetative propagation, avoidance of juvenility, size control, and acquisition of biotic stress resistance [7].
Propagation of crop plants, involving the formation and development of new individuals in the establishment of new plantings, is usually accomplished by the use of either seeds or the vegetative parts of plants.
A different and more practical approach has been the recent development of seed-planted, hybrid varieties of globe artichoke, which transformed this vegetable from a labour-intensive, perennial crop, maintained by vegetative propagation into a crop better fitting the needs of modern agriculture.
Moreover, due to the standard vegetative propagation of this crop, viruses are transmitted from one generation to the next [ 54].
and ornamental plants (lily, tulip, crocus, narcissus, etc).. Thanks to the absence of recombination, crops that reproduce by asexual propagation evolve mainly through mutation and drift.
