Abstract

Two snap bean variety trials were planted at the Gurabo Substation farm in east-central Puerto Rico. In the first trial five pole-bean varieties were tested. The varieties used were: Florigreen, Blue Lake 92, Blue Lake 228, Blue Lake 231, and Kentucky 191. Of these varieties Florigreen had the highest yield with a production of 4.30 tons of green beans per acre. It also showed high resistance to bean rust and mosaic, two of the worst diseases of beans. In the second trial eight lines and two commercial bush varieties were tested. They are B2971-1-1, B3370, B3095-3, B3489, B3365, B3125 x 5-2, B2567-1, B3076, Wade, and Top Crop. In this trial line B2971-1-1 produced the best yield with a production of 4.05 tons of green beans per acre, which is very high for bush beans in Puerto Rico.
