Nonshattering

· Selecting nonshattering genotypes or developing techniques to overcome shattering. ❋ Unknown (1996)

Because the gene for nonshattering is recessive, the selection of nonshattering types should be rapid, and true breeding should be immediate. ❋ Unknown (1996)

This species was domesticated in the distant past and is a largely nonshattering plant that retains its grain so people can harvest it. ❋ Unknown (1996)

The main difference between the two is that the cultivated type has much larger grains and is nonshattering (holds its seeds). ❋ Unknown (1996)

Partially domesticated in the distant past, this species is largely nonshattering - that is, it retains most of its grain so farmers can harvest them conveniently. ❋ Unknown (1996)

Jojoba is nonshattering, there is enough delay between the time the seeds mature and the time they drop to allow for harvesting the crop. ❋ Unknown (1985)

Artificial domestication experiments show that it is possible to breed nonshattering cereals quite quickly. ❋ Unknown (2010)

But Old World archeological data indicates that nonshattering cereals appeared only gradually, and typically only after the emergence of another domestic trait: larger grain size. ❋ Unknown (2010)

So the nonshattering trait might have lagged behind other domestic traits because it required an optimal combination of mutations that balanced seed retention for both harvesting and threshing. ❋ Unknown (2010)

Why would the nonshattering trait emerge later than larger grain size? ❋ Unknown (2010)
