Fort Pierce ARC Research Report RL-1981-3 June, 1981

Black Bean Variety Trial Fall 1980 !

P. J. Stoffella and J. B. Brolmann SFp /

Sizable black bean market has developed in Florida ovei"the- 'pAt r/O
few years. This is primarily due to the substantial influx of Cubans and

Haitians into south Florida. Black beans currently are being shipped

from New York State to meet Florida's increasing demand. The purpose

of this investigation was to evaluate several black bean genotypes for

growth and yield characteristics under south Florida's environmental



Eleven black bean genotypes were planted at the Agricultural

Research Center, Fort Pierce, Florida (ARC-FP) on October 1, 1980.

The genotypes consisted of: three plant introduction lines, Mexico

PI 209465, El Salvador PI 304116, and PI 251049; three single plant

selections, 70001, 70002, and 70003 by Dr. R. F. Sandsted, Cornell

University; three cultivars, Arbolito, San Andres #1, and Venezuela

#54; and two commerical cultivars, Black Turtle Soup and Strain 39,

presently grown in the United States.

Land preparation consisted of incorporating approximately 2.24

mt/ha of dolomitic limestone. Raised beds were spaced at 2.1 meters

centers with a 105 cm width. All beds were fumigated with Vorlex

(96 1/ha). A fertilizer application of 4-16-4 (1,568 kg/ha) was

broadcast over the beds followed by an application of 8-12-20 (2,352

kg/ha) banned under a strip of.plastic mulch (25 cm wide) (1) placed in

the center of each bed.

All genotypes were seeded at 5 cm within row spacing on October

1, 1980. Two rows (61 cm apart) were planted on each bed, each equidis-

tant from the strip mulch on opposite sides of the mulch. Plots were

3.66 meters in length. A randomized complete block design with three

replications was used.

Prior to harvesting, lodging ratings, on a scale of 1 (erect) to

5 (prostrate), percent pod dryness, and percent leaf retention were

taken. The middle 3.05 meters of each plot was hand harvested on

January 6, 1981. All remaining leaves were removed and plants placed

in burlap bags, air dried approximately 30 days, and weighed (biological

yield). Seed yields were determined by processing plants through a

portable bean thresher.


No seed or biological yield differences occurred among genotypes

(Table 1). However, seed yield ranged from 1,115 to 1,389 kg/ha for

Strain 39 and 70001, respectively. El Salvador PI 304116, Black Turtle

Soup, and Strain 39 had the highest harvest indices when compared with

the other genotypes. This suggests that these cultivars have a greater

photosynthetic efficiency since a higher percent dry weight accumulation

had gone into reproductive plant parts (seeds) than into vegetative plant

parts (roots, stems, pods),

Lodging resistance was highest for Arbolito, San Andres #1,

Venezuela #54, PI 251049, 70002, and 70003 when compared with Black

Turtle Soup, Mexico PI 209465, and El Salvador PI 304116 (Table 2).

PI 251049 had significantly lower percent pod dryness and higher

leaf retention at time of harvesting when compared to the other

genotypes. No differences for percent pod dryness and leaf retention

occurred among the other genotypes.


Our data show that black bean can be grown during the fall

season in south Florida. Although no seed yield differences occurred

among genotypes, further yield evaluations under different seasons are

needed. Lodging tolerance is an important black bean characteristic

for seed production, particularly under the wet and humid growing

conditions of Florida. Lodged plants during harvesting would decrease

harvestable yield when combined and increase pod and seed rot when in

contact with the soil. Arbolito had the highest lodging tolerance in

our trial. Adequate pod dryness and low leaf retention during

harvesting is needed to facilitate harvesting with the combines.

McMillan 12-D3 with low percent pod dryness and high leaf retention may

have considerable seed yield losses during the combining operation.

More research in areas of plant population, cultural practices, lodging

resistance, and pest management is needed to promote high yields and

grower acceptance of black beans in Florida.
