The effects of modifying air temperature, soil temperature,
and soil moisture levels on flowering, fruiting, and chemical composition
of Tendercrop snap beans were studied in experiments in
the field and in the greenhouse during 1961, 1962, and 1963.
High maximum temperatures of 95-105° F. during bloom reduced
the percent set...
Interspecific hybridizations between P. vulgaris and P. acutifolius
and between P. vulgaris and P. lunatus were investigated. Prefertilization
events were similar in inter- and intra-specific crosses. Fertilization
was completed in all crosses and the time of fertilization was
dependent on the maternal parent, reflecting differences in the time of
maturation...

Inheritance of the volatile components in bush snap beans,
O.S.U. 58-110 X 'Romano' cross and reciprocal, was determined
using gas-liquid chromatographic technique with gas-entrainment
on-column trapping. A sample of 10 to 14 pods averaging 5 grams
from a single plant was found to be adequate for F₁, F₂, and backcross...
The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...
During 2 seasons effects of high and low irrigation (water applied
at -0.6 and -2.5 bars soil water potential, respectively) and
density were evaluated on yield parameters and flower/pod development
at mainstem nodes 2 and 6 (terminal) of 'Oregon 1604', a determinate
snap bean. High and low plant densities were...
