Davis Class IX
PBA Overview:
The Seed Biotechnology Center at UC Davis has pioneered the Plant Breeding Academy, a program designed and tailored for seed industry personnel. It provides a rare opportunity to develop talents within the Seed Industry. This Academy offers a unique curriculum that matches and exceeds the depth and breadth of a traditional Ph.D., as it is solely dedicated to the field of Plant Breeding and is taught by experienced plant breeders. This program specifically addresses the limited availability of trained plant breeders emerging from academic programs. Through initiatives like the UC Davis Plant Breeding Academy, seed associations such as ASTA, Euroseeds, and their member companies actively support a dynamic ecosystem that promotes ongoing learning, collaboration, and the relentless pursuit of excellence in the field of plant breeding. Since 2006, the UC Davis Plant Breeding Academy has graduated more than 400 students, making a significant contribution to driving innovation and meeting the evolving challenges of plant breeding. Over two years, participants engage in six immersive sessions in Davis, California (USA) at UC Davis campus with exterior visits of seed companies, research centers and collaborative programs.
Course goal: This course develops the skills and abilities of current industry personnel to enable them to become independent breeders or more valuable contributors to larger breeding programs.
Who should attend? The course is targeted toward personnel currently involved in plant breeding programs who lack the academic background in genetics theory and practice to advance as independent breeders. Current breeders who desire a refresher course or would like to broaden their expertise would also be potential participants.
Class Location & Dates:
All six sessions of the PBA IX course will take place in Davis, California, on the UC Davis campus or nearby if necessary. This schedule will allow participants to maintain their current employment while enrolled in the course. In-person attendance at all six sessions is required to graduate. Each session is 5-6 days in length and subject to change if needed to fit in the planned curriculum.

Application & Tuition:
Application Process: To provide a personalized learning environment, the program is limited to 20 participants. Applicants should complete the online application and upload their resume in order to be considered for enrollment. Applicants' background and experience will be reviewed to ensure they meet the minimal requirements before acceptance. Applicants must have a Bachelor of Science degree (or demonstrate equivalent professional experience) and have taken introductory courses in statistics and genetics. Practical experience, academic standing (GPA or equivalent) and rationale for participation in the Academy will be evaluated. Among applicants meeting the program requirements, acceptance will be on a first-come, first-served basis. Acceptance is not secured until paperwork is signed and the deposit is received.
The early registration discount ($1,000 off) is available for applications received prior to September 1, 2023.
Tuition: (All pricing is in United States Dollar) Tuition is $26,000 per participant for the two-year program (or $25,000 if you apply before the early registration deadline). Tuition includes all course materials, instruction and administrative fees. Lunches and breaks during sessions in Davis are provided. Travel, accommodations and other meals during in-residence sessions are not included. A non-refundable deposit of $1,000 will be due within 30 days of acceptance into the Academy.
An invoice requesting the balance of the first year's tuition (half of the total tuition, after the deposit is paid) will be sent and must be paid prior to the start of the course. The second tuition payment will be due prior to the start of the second year. Exact due dates will be listed on your invoice document. No refunds will be issued after a payment is made. Payment procedures will be provided to applicants following acceptance into the Academy.
