Abstract
Seeds were collected from five randomly selected trees of Capparis decidua
from each of two sites from Rajasthan (Hanumangarh, Bhadra) and Haryana
(Sirsa, Hisar) provenances during September 2005. The seeds of all the twenty
progenies arising from four provenances were used for provenance testing in
nursery and seed storage up to six months. Fruit diameter ranged from 14.79 to
22.88 mm with a general mean of 17.83 mm. Variability for fruit diameter was
comparatively higher in Hanumangarh and Sirsa. Analysis of variance showed the
presence of significant variation among progenies for germination per cent, plant
height and collar diameter, whereas significant variation among provenances were
observed for plant height and collar diameter. Medium values of phenotypic
coefficient of variation and little difference from genotypic coefficient of variation
were observed for all the three characters, viz., germination per cent, plant height
and collar diameter. Heritability estimates and genetic advance were also found
high for all the characters under study. Progeny number 8 from Bhadra
provenance was found overall best for all the three characters viz., germination per
cent, plant height and collar diameter. Progeny number 6 from Bhadra was found
significantly superior than general mean for plant height and collar diameter
whereas progeny number 1 from Hanumangarh was found significantly superior
than general mean for germination per cent and plant height. In general, the
provenances like Hanumangarh and Bhadra were found superior for seedling
characters.
Standard germination of fresh seeds varied from 53.74 per cent in progeny
no.17 from Hisar to 62.21 per cent in progeny no.1 from Hanumangarh with a
mean of 59.08 per cent. The average germination per cent of fresh seed (59.08)
was reduced to 44.87 per cent three months after storage and which was further
reduced to 32.73 per cent six months after storage. The reduction in both vigour
index-I and vigour index-II were observed higher than standard germination for all
the progenies up to six months of storage.
