Sentence examples for crops propagated from inspiring English sources

They are seed-sterile crops propagated clonally and this makes them vulnerable to a rapid spread of devastating diseases and at the same time hampers breeding improved cultivars.

The process of domestication seems to have been diffuse, with prolonged cultivation of undomesticated forms, and prolonged genetic exchanges of domesticated forms with local wild relatives, at least for crops propagated by seeds [ 11, 12].

This can be done without difficulty by forming a planting hole using a machete and so is particularly appropriate for crops propagated by corms or stem cuttings or those where multiple seeds are placed in the same pocket and inter-pocket spacing is relatively large, such as for maize.

In Musa, the challenges are to identify and characterize the relevant genes and genetic diversity, and then to utilize this variation in a largely sterile crop propagated by tissue culture.

The particulars of the mating system (i.e., whether it is selfing or outcrossing and whether the crop is propagated by seed or clones) will affect whether the variation is distributed among populations or within populations (Hamrick and Godt 1996).

Although commercial database packages are available for plant breeders, for example, Agrobase® (Agronomix, Inc., Winnipeg, Canada), these are predominantly focused on annual agricultural crops rather than perennial and clonally propagated crops such as apple.

Just as farmers choose certain crops they propagate across their fields, fungi also physically aid in dispersing the bacteria they are cultivating.

Viruses are important constraints to the movement and propagation of plant germplasm, especially for vegetatively propagated crops such as banana and plantain.

Because desirable genetic and epigenetic genomic variation can be captured in clonally propagated crops such as peach, unique opportunities for clonal crop improvement are possible.

In seed-propagated crops, domesticated types are characterized by a lack of seed dispersal at maturity and a lack of seed dormancy [ 7], while in clonally propagated crops, the reduction of sexual fertility and adaptations facilitating vegetative propagation have generally been reported [ 8].

Nearly all commercially important perennial fruit and nut crops are clonally propagated; i.e., their varieties are multiplied vegetatively by one means or another.
