Use of Simple Sequence Repeats (SSR) to Determine Incidence and Effectiveness of Self and Cross-pollinated Avocado Fruit in Southern California

  • May 14, 2013

SSR technology is a powerful tool to determine the pollen parents of avocado progeny of known maternal genetic background. The four SSR markers we have selected for use to determine pollen parents are powerfully informative for the range of cross pollinizing cultivars available in the selected orchards and, therefore, highly capable of discerning the specific pollen parent of each sampled fruit. The cultivars included in the study are Bacon, Ettinger, Fuerte, Harvest, Hass, Lamb Hass, Marvel, Nobel, SirPrize and Zutano.

Screening and Evaluation of New Rootstocks with Resistance to Phytophthora cinnamomi

  • May 14, 2013

Ultimately, the control of Phytophthora root rot (PRR) of avocado will be accomplished with resistant rootstocks. Our goal is to find rootstocks that will eliminate Phytophthora cinnamomi as a serious pathogen on avocado. Our ability to find such rootstocks has been enhanced as a result of our breeding blocks where we focus on crossing already resistant rootstocks. Our objectives over the life of this project have been to collect, select, breed and develop avocado germplasm that exhibits resistance to Phytophthora root rot of avocado.

Screening and Evaluation of New Rootstocks with Resistance to Phytophthora cinnamomi

  • May 14, 2013

Ultimately, the control of Avocado root rot will be accomplished with a resistant rootstock. This project has already provided the industry with several new tolerant rootstocks, which are greatly improving the yields of avocado on land infested with Phytophthora cinnamomi. The goal is to find a rootstock that will eliminate Phytophthora cinnamomi as a serious pathogen on avocado. Our ability to find such a rootstock has been enhanced as a result of our breeding blocks where we focus on crossing already resistant rootstocks.
