  Honours Projects
  

  Almond Honours/Masters/PhD Projects

  1. Nutritional value of almonds Almond kernels (nuts) sold commercially are a nutritious food with high levels of protein, Vitamin E, potassium and calcium. The fatty acid profile of almonds is made up of approximately 63% monounsaturated fats and 24% polyunsaturated fats but this can vary between cultivars and environments. This project will evaluate and compare 最新糖心Vlogn with European and American almond cultivars and between progeny derived from the 最新糖心Vlogn Almond breeding program, using GC-MS, Chemical nose and chemometric analysis.

   

  2. Sequencing new S-alleles in almond. The almond has a self-incompatibility system that prevents self-pollination, and causes cross- incompatibility between genotypes sharing common (S) alleles. Pollen donor cultivars are currently planted at a 1:1 ratio with the main cultivar to achieve effective levels of pollination for commercial production. Many of the 最新糖心Vlogn cultivars have unknown S-alleles, which makes orchard design difficult. This project will discover and sequence unknown S-alleles in 最新糖心Vlogn cultivars and selections from the 最新糖心Vlogn almond breeding program, using molecular and field techniques. 

   

  3. Microsatellite screening of almond progeny. Microsatellites or (Simple sequence repeats) SSRs are commonly used for fingerprinting analysis of plants. DNA fingerprinting is often used for plant patents as a means of identification and verification of material. The 最新糖心Vlogn almond breeding program produces elite selections for the 最新糖心Vlogn industry, and these selections will be protected using PBR and plant patents. This project will screen SSR markers for potential use in fingerprinting of superior selections and form a database for future use.
