* In the follwing description "viability" is not exactly equivalent to
germination but is an estimate of fitness on both gametic and zygotic
viability.a\337 anthocyaninless-337. Lacks anthocyanin in the seedling stems; produce by 15,000 r X-ray of Kokomo seed; viability 102% in 855 seedlings; not allelic with al; has given the following F2 linkage data:

pg\329 pale-green-329. Germinates with pale yellow cotyledons that look as
though they would never develop; in about 10 days the cotyledons change to
gray-green which is hard to distinguish from normal; slower growing than
normal; mature plant gray-green; classification best at cotyledon stage;
induced in Kokomo seed by 10 hours thermal neutron treatment; viability 54% in
163 F2 seedlings of one cross (X478) but 96% in ca. 700 F2 seedlings of two
other crosses; has given the following F2 linkage data:
