Phenotypical observations of Sp-sp segregation in F2 lines.<p>

Hall, R. J. and C. K. Kuyper.<p>

In three F2 segregating lines in 1959 from crosses of parents all having
genotype sp/sp, small percentages of +/+ or sp/+ phenotypes were observed.  F2
lines and observations are described as follows:<p>

<pre>
                                  Percentage of +
                                  phenotypes observed

1.  Libby C47 x L 3700                    8
2.  Libby C47 x R.I.P.I. 1969             7
3.  Libby C47 x R.I.P.I. 1864             6

Libby C47 - sp/sp has the parentage Indark x Lanii
L 3700 - sp/sp  I. L. Nonnecke Lethbridge, Alta.
R.I.P.I. 1969 - sp/sp  Russian Institute of Plant Introduction
R.I.P.I. 1864 - sp/sp  Russian Institute of Plant Introduction
</pre>

It is noted that the percentage of occurrence of + phenotypes in all three
lines is nearly the same.  All lines have one parent in common vis Libby C47.<p>
