A male sterile pepper (C. annuum L.) mutant.
1. After treatment of dry seeds of red pepperCapsicum annuum L. with X-rays a male-sterile mutant was discovered in the M2. 2. The male-sterile mutant segregates in a ratio of 3.28:1 (χ(2)=3.148, probability 0.07). 3. After an alternative cultivation of male-sterile plants and of a variety with good combining ability relatively good fruit-setting and seed production was obtained. 4. Grafting of male-sterile scions to normal stocks does not affect the male-sterile phenotype.
