Because the majority of crops (cereal crops) are wind pollinated.
In self pollinated crops, hybrid vigour is not just like the cross pollinated crop e.g maize.cross pollination in self pollinated crop produce low seed set and cost of hybrid seed increases.less cytoplasmic male sterility and fertility restorer gene in mostly self pollinated crop.
self pollinated
you'd get a uniform genetic composition for good or bad. you can get a uniform crop or you may get inbreeding problems
they are self-pollinated!!
Barley is predominantly self-pollinated, aided by the wind..
Sampaguita is primarily cross-pollinated, where the transfer of pollen occurs between different flowers by insects like bees. In some cases, self-pollination can also occur within the same flower when the pollen is transferred from the anther to the stigma.
Sesame is primarily a self-pollinated crop, as it has perfect flowers that contain both male and female reproductive organs. However, some cross-pollination may occur due to wind or insects.
Cilantro is a self-fertile plant, which means it has the ability to self-pollinate. However, it is primarily wind-pollinated, so cross-pollination can also occur with the help of insects.

Yes
•spreads rapidly •perennial plant •Silverweed flowers are insect pollinated as well as self-pollinated as they are hermaphrodite
self-pollinated or self-pollinating
