2. Additions or Corrections to last year's notes.
- The gene ramosa has appeared in another stock, a Leaming inbred. It has proved allelomorphic with ra1. This makes the fourth occurrence of this gene in our stocks.
- Preliminary tests with la2 give an indication of linkage with su. No crossovers occurred in a row of 20 plants. It is probably allelomorphic to la1.
- Micropyle color Mc is a modifying factor, rather than allelomorphic. Backcrosses of PMc/pmc to pmc showed a segregation into PMc, Pmc and p plants, which could not occur if Mc were allelomorphic to P.
