A Study of the Seed Proteins of SynthesizedBrassica napuswith Respect to its Parents

Abstract
The parental and hybrid seed of three synthesis experiments (B. oleracea × B. campeslris = B. napus) has been analysed by acrylamide gel electrophoresis for general proteins and certain enzymes. A serological study has been made of one of the synthesis experiments. The protein and enzyme patterns of the newly established hybrids are compared with those of two well-established varieties of B. napus. The results suggest that the hybrid seed has no protein which differs from those in the parental types, and that the protein spectrum of the hybrid is a summation of some of the proteins found in the parents. The analytical methods employed are discussed with particular reference to their value as an assessment of plant genotype.
