sugars from 0.59 to 3.47 per cent and reducing sugars from 0.12 to 1.56 per cent. The most
promising accessions for TSS is Bandarwada-3 with 22.40 o Brix followed by Dabose-1 with
o
17.05 Brix. Korikanthimath and Desai (2005) have reported a TSS range of 6 to 12 o Brix ;
Nair (1986) reported as 11.04 to 16.44 per cent; Khan and Pandya (1936) recorded average
TSS of 14.83 per cent ; Joshi (1994) showed 16.45 per cent and Gosavi (1998) recorded
16.47 per cent .However, the TSS of “Konkan Amruta”, the first released variety has been
reported to be 9.08 per cent (Patil et al., 2005a).

Joshi (2005) reported that, while producing RTS, a TSS of 20 Brix and 0.30 per cent
acidity is usually maintained by addition of sugar. But when accession like Bandarwada-3 is
used as raw material for making RTS whose TSS and total acids content in pooled juice is
o
22.40 Brix and 0.64 per cent, addition of sugar and citric acid is not required. Such
accessions with promising TSS content can also be employed in preparation of syrup and
squash by minimizing the quantity of sugar added.
As a result of mapping the values by point to grid method (DIVA-GIS software-Fig.3),
o o
there were five categories namely 19.0 to 22.0 Brix (red grids), 15.0 to 10.0 Brix (orange
o o
grids), 12.0 to 15.0 Brix (yellow grids), 8.0 to 12.0 Brix (light green grids) and a minimum
o
range of 5.0-8.0 Brix (dark green grids).

As there is only one accession (Bandarwada 3) having TSS in range of 19.0-22.0
Brix, it was not depicted on the map. However, this tree was located in Pernem taluk.
Similarly, maximum diversity for TSS was found in Pernem, Bicholim and Canacona taluks.
Total acids in fruits i.e fresh rind ranged from a minimum of 1.22 per cent to a
maximum of 11.24 per cent with a grand mean of 4.12 per cent. Total acids in juice ranged
from a minimum of 0.43 per cent to a maximum of 10.97 per cent, with a grand mean of 3.72
per cent. Average was drawn for total acids per cent in fruit, juice and extract left out. This
data ranged from a minimum of 1.2 per cent to a maximum of 7.36 per cent. The grand mean
was 3.78 per cent for all 268 accessions under study. As a result of subjecting the data to
point to grid plotting on Goa map, a grid map was obtained with grids of five different
colours viz., red, orange, yellow, light green and dark green which illustrated clusters with
average acids ranges viz., 6.0-7.0, 5.0-6.0,
4.0-5.0, 3.0-4.0 and 1.0-3.0 respectively. Red grids were spotted in Pernem, Bardez,
Bicholim, Sattari, Tiswadi, Sanguem and Canacona talukas; orange grids depicting average
acids ranging from 5.0-6.0 per cent were spotted in Pernem, Bardez, Bicholim, Sanguem,
Quepem and Canacona talukas. Accessions having medium average acids ranging from 4.0-
5.0 per cent were found in all the talukas of Goa. Lower range of average acids (3.0-4.0 per
cent) illustrated by light green grids were spotted in all talukas except Bicholim Ponda and
Mormugao talukas. The lowest range of average acidity (1.0-3.0 per cent) symbolized by
dark green grids were seen in Sattari, Bicholim, Bardez, Tiswadi, Salcete and Quepem
talukas.
An attempt was made to classify the accessions into three groups based on two
criteria viz., TSS and total acids in juice. The results showed that for three clusters viz., 1, 2
o
and 3, the cluster means were 7.34, 11.66 and 8.36 respectively for TSS ( Brix); whereas it
