Genetic improvement of broccoli. - HH0903SFV

i) To produce experimental inbred lines with smaller bud size, improved bud uniformity, stem smoothness and succulence, and resistance to hollow stem, (years 1 - 4) and then use these inbred lines:-
(ii) To establish the genetic variability for shelf life in high quality broccoli genotypes.
(iii) To produce "calabrese" type breeding material with the ability to overwinter for assessment of the feasibility of extending early season production.
(iv) To produce experimental inbred lines with late maturity and increased cold tolerance and then use these:-
(v) To establish the genetic variability for cold tolerance.
(vi) To identify and characterise new sources of pest and disease resistance, in particular resistance to cabbage aphid (Brevicoryne brassicae), spear rot (Pseudomonas spp., Erwinia spp.). black rot (Xanthomonas campestris) and TuMV.
(vii) To devise, develop and apply the techniques for anther/microspore culture and marker assisted selection (MAS) to speed up and increase the efficiency of breeding in vegetable brassicas. Demonstrate their efficacy by applying them to breeding for clubroot resistance and use the information gained to devise strategies for breeding for resistance to cabbage aphid.
