Using apomictic tetraploids to make a self-incompatible diploid Pensacola bahiagrass clone set seed
Article Abstract:
The transfer of apomixis to Pensacola bahiagrass (PD) was attempted. A self-incompatible PD clone was crossed with six apomictic tetraploids. Almost all of the plants produced by the crosses were diploid and resembled PD. Such a result could be due to the production of selfed progeny of the PD clone by the mentor process. The intervention of foreign pollen which broke down the self-incompatibility of the original clone was theorized. Four plants were triploid and apomictic. This was ascribed to dominant genes contributed by the apomictic parent strains.

Female sterile mutant in pearl millet: evidence for initiation of apospory
Article Abstract:
Cytological examination of 273 ovules isolated from sterile mutant pearl millet females was undertaken to investigate the cause of sterility and to determine a link to the developmental process leading to aposporous apomictic reproduction. Results show that all the ovules are small and deformed. One half do not possess embryo sacs while 35% have more than one embryo sac. This is suggestive of apospory potential. Endosperm tissue was found in six of the all the ovules studied. Apomictic development regulation is indicated in this recessive mutation.

Genetics of red and purple plant color in pearl millet
Article Abstract:
A study was done to determine the genetics and allelic relationship of red plant and purple plant phenotypes in pearl millet. It was shown that crossbreeds of red and purple plants with normal plants are controlled by dominant genes. Crosses between red and purple plants showed only red progeny which suggests that red and purple are allelic but red is dominant over purple.
