HORTICULTURAL TRIALS WITH BUSH AP BEANS, SPRING 1958
/. Howard W. Burdine and V. L. Guzman 1
; i.One replicated and one observational snapbean trial were conducted in the
spring of 1958. Twenty-four varieties and breeding lines were obtained from
Dr. J. C. Hoffman, Chairman of the Southern Cooperative Snapbean Trials, Nos.
17-24, Table 1, in the replicated plot and 1-16, Table 2, in the observational
plot. To these twenty-four lines were added six from other sources. These includ-
ed varieties and breeding lines, Nos. 25-29 in Table 1 and varieties 30-32 in
Table 2.
The soil on which the plots were grown was well matured Everglades peaty muck
that had been fallow since 1955.
Soil samples taken in 50-ft. square blocks indicated good uniformity of
residual fertility with pH ranging from 5.35 to 5.80. Fertilizer was broadcast
before planting according to Experiment Station recommendations. Little leaf
chlorosis was observed, compared to the amount observed in previous years.
Plot size and design. Plot size consisted of single rows 25 feet in length as
planted and 20 feet in length as harvested, with four replications for replicated
trials, Table 1. Observational plots were unreplicated. Rows were 36 inches in
width and seed spaced 1 inch apart in the drill.
Disease and Pest Control. Routine weekly spray applications of sulfur wp. with
50O WT were applied April 10, 17, 25 and May 1. Rust developed on Tenderlongs
used in guard rows and rapidly spread to susceptible varieties after the high winds
and heavy rain of May 10.
Special Conditions. Winds with gusts up to 55 miles per hour were recorded on the
Everglades Experiment Station anemometer located about i mile away on May 10, 1958.
This was two days before first harvest on earliest varieties and 6 days before
harvest on latest varieties. These high winds and beating rains probably affected
yields of all pickings from later varieties as well as later pickings from earliest
varieties.
Wade and Asgrow Black Valentine were used as the check varieties.
RESULTS
Replicated Trial, Table 1. The high yielding line in this trial was B2567-1.
Differences between B2567-1 and Black Valentine type #939 were not quite signi-
ficant at the .05 level. This dark seeded line, B2567-1, again exhibited no
hollowness in the sample examined, and gave 62.1% of its total yield in the first
picking in a three picking harvest. It is a dark green podded bean with satis-
factory smoothness and uniformity. The line, selected at the Southeastern
Vegetable Breeding Laboratory, has recently been released to seedsmen under the
name "Extender".

Station Mimeo Report 59-30
Yields of C-12-6, Mississippi Agr. Exp. Station breeding line which was top
yielder last season, dropped sharply this season, probably partly as a result of
very severe rust infestation. Pods of this breeding line were very rough this
year, more so than in the 1957 season.
B3370, another S.V.B.L. breeding line that had given good performance in the
1956 and 1957 trials, ranked eighth in yield with no hollowness observed in the
1958 season, compared to about 28% of the pods exhibiting very slight hollowness
in 1957. It exhibited a moderate amount of rust this season compared to a slight
amount of rust in B2567-1.
XP219 exhibited no rust whatever.
The Black Valentine breeding lines from Dr. W. J. Zaumeyer of U.S.D.A. again
yielded well, with #939 ranking second in terms of rank. However, these lines
exhibited rust lesions equal to the Asgrow Black Valentine check.
Observational Trials. Southeastern Vegetable Breeding lines, 3097-2, B2971-1-1,
B303S-1-l and B3125-x-5-2, ranked high in yield with slight to moderate pod hollow-
ness in 24 to 56% of the pods observed. However, B3034-1-1 and B2971-1-1 had a
low percentage first picking. B2971-1-1 and B3125-x-5-2 had a high percentage
first picking, about 55%. The former had little rust and the latter had a moder-
ate amount.
Tenderwhite, XP225 and E21, exhibited no visible rust lesions.

(2) Days to Maturity: Number of days from planting to the first picking.
(3) Rust Rating: Rust (Uromyees phaseoli typical Arth.) badly infested the plot
in spite of routine control measures. 1 a no observed lesions to 8 very severe
infestation. Table 1, data are means of four replications; Table 2, data single
plot ratings.
(4) Seedling Vigor: Ratings were made 15 days after planting. 1 poor vigor
to 4, excellent. Table 1 give means of ratings on four replications. Data in
Table 2 are single plot ratings.
(5) Plant Height: Mean height of 10 plants per plot. Data in Table 1 are per
plant means of four replications or 40 plants. Data in Table 2 are means of 10
plants from single unreplicated plots.
(6) Pod Length: Data in Table 1 and 2 are means of 25 randomly selected #51jeve
sized pods.
(7) Pod Color: L : light green, M a medium green as Tendergreen, D a dark green.
(8) shape of Pods: F flat, 0 a oval, R : round, H : heart shaped pods.

(9) Pod Roughness: VS very smooth, S = smooth, SR a slightly rough, VR s very
rough.
(10) Pod Uniformity: VU s very uniform, S = satisfactory uniformity, SM =
severely mixed.
(11) Pod Straightness: S x straight pods, SC a slightly curved pods, VC a very
curved pods, C2D a pods curved in two directions.
(12) Percent of pod hollowness: Percent of pods in 25 No. 5 sieve sized pods
exhibiting "hollow pod", a many pointed star shaped cavity between the seed.
(13) Severity of pod hollowness: A rated severity of "hollow pod" based on
depth and size of lesion. 1 a no hollowness to 8 a very severe pod hollowness.

acre yield.
(15) (16) (17) Percentage total yield in each of three harvests.
(19) Preference: A rating 1-4, 1 most preferred to 4 least preferred based
