Recover, propagation
and storage
- Battipaglia's Section
owns several accessions of typical Campania horticultural crops: "Pomodorino
di Corbara", "Pomodorino del Vesuvio", "Pomodoro di Sorrento",
"Fagiolo di Controne", "Fagiolo occhio nero di Oliveto Citra".
For each ecotype, several biotypes were collected in typical cultivation areas.
Every year, this germplasm is propagated both in situ (at origin areas)
and ex situ (at ISCI farm).
"Pomodorino di Corbara" is a tomato indigenous of Corbara (Salerno)
on Lattari mountains while "Vesuviano" is indigenous of Vesuvio
slopes. These ecotypes derive by selections of old tomato paste varieties
(such as "Fiaschella", "Principe Borghese", "Re Umberto",
etc.) carry out by farmers.
"Fagiolo di Controne" is cultivated at an internal hilly area of
Campania Region (Alburni Mountains, Salerno), while the bean "occhio
nero di Oliveto Citra" is indigenous of Oliveto Citra (Salerno), internal
hilly area of Sele plain. These bean ecotypes grow at 200-500 s.l.m. in calcareous
soils.

Bio-morphological,
agronomic and qualitative characterization
- For all the accessions,
descriptive schedules for morphological characteristics, length of phenophases,
yield and main qualitative characteristics of the product, were set-up.
"Pomodorino di Corbara" shows indeterminate plant growth and small
size fruits (from 8 to 20 g). Results of researches showed a considerable
variability between the accessions, due principally to different shape of
the fruits: elongated (length/width ratio from 1,5 to 2), ovoid (length/width
ratio from 1,2 to 1,4) and round. This ecotype is very interesting for processing
(canning of whole, unpeeled berries with the juice, at 5-6° Brix, obtained
from the same fruits).
"Pomodorino del Vesuvio" shows indeterminate plant growth with fruit
up 20 g, ovoid-pear-shaped and with mucro. This ecotype shows very firm berries
with no joint-less trait and with difficulty of stalks detach. Owing to these
characteristics fruits kept aside as hanging tomatoes on a long time.
"Pomodoro di Sorrento" shows indeterminate plant growth producing
ribbed big size fruits. Clear-red tending to pink berries have round shape,
a large number of loculi and remarkable pulp thickness with sweet taste. This
ecotype is used for fresh market because it has uninterrupted harvesting and
short shelf life of the fruits.
"Fagiolo di Controne" is climbing beans provided of yellow stringless
pods, at waxy ripening, with 5-7 ovoid white seed.
"Fagiolo occhio nero di Oliveto Citra" is a climbing beans provided
of yellow stringless pods, at waxy ripening, with 4-5 seeds. Seed shows ovoid
shape, white colour and a violet-black coloured area around hilum with different
shape and extension in relation to different biotypes.

Molecular
characterization
- Different accessions
of the ecotypes "Pomodorino di Corbara" and "Fagiolo di Controne"
were characterized by AFLP markers. A great genetic variability was found
for "Pomodorino di Corbara" while, for "Fagiolo di Controne",
data revealed a considerable similarity among the tested types.
- Molecular characterization
(by M13-PCR) of the bean "occhio nero di Oliveto Citra" showed that
some biotypes were identical to each other, whereas genetic variability was
observed for other biotypes. One out ten biotype was genetically more similar
to two bean ecotypes used as comparison with respect to the other biotypes
of the bean "occhio nero di Oliveto Citra".

Selection
of promising biotypes, identification of suitable crop management
- For each ecotype were
selected and described biotypes promising for yield and qualitative characteristics.
Also were studied appropriate agronomic technique to obtain satisfactory yield,
for quantity and quality, at lower cultural cost. In order to ask for quality
marks ("DOP", "IGP", ecc.), the results of these researches
were used.
