WebJan 1, 2010 · Estimates of inbreeding depression were negative for all other traits except days to flower. Six estimates for barrenness percentage were also positive (Good and Hallauer, 1977 ). These expressions of inbreeding also agree with previous reported effects for reduced vigor and plant size, later flowering, and increased barrenness.
WebMay 14, 2024 · However, inbreeding may alter these characteristics which could make it harder for inbred plants to reproduce, meaning that populations would end up shrinking even faster.
