There are differences in needle and cone morphology and seed size between the two populations.

Genes enhancing the agronomic traits of wild perennials, increased seed size, for example, could be brought in from domestic grain relatives.

The waste ratio, however, is 30 percent or more, due to the seed size.

The study showed that seed size was not a determinant of post dispersal seed survival.

Later, he pioneered investigations of seed size and reproductive output of plants in relation to habitat.

Again the best 50 plants were selected, this time based on yield per head, seed size, shortness, and free threshing ability.

The selection methods described above have increased seed size and yield by about 10 to 18% per cycle.

Increasing seed size is one way to increase grain yield.

He was able to show that even in populations homozygous for all traits, i.e. without genetic variation, seed size followed a normal distribution.

Dry beans are divided into classes with a range of seed sizes, colors, and shapes.
