Abstract
ABSTRACT
The study entitled “Evaluation of Clonal Seed Orchard of Grewia optiva Drummond for
morphological and fodder quality parameters” was conducted in Experimental Field under
Department of Tree Improvement and Genetic Resources, Dr. Y.S. Parmar university of Horticulture
and Forestry, Nauni, Solan (H.P.). The Clonal Seed Orchard was established during the year 2013
from cuttings obtained from the best families of Seedling Seed Orchard that were evaluated and
screened. There were two main objectives behind this study viz. (i) To evaluate the Clonal Seed
Orchard of Grewia optiva Drummond for morphological characteristics and (ii) To study the variation
in fodder quality parameters among different clones in the Clonal Seed Orchard. The present study
was based on 21 clones, having three plants of each clone. These include BI-3, BI-4, CH-1, CH-3,
CH-6, HA-2, HA-3, HA-4, MA-2, SH-3, SH-7, SI-7, SI-10, SI-14, SI-15, SI-16, SO-1, SO-3, SO-4,
SO-7, SO-10. The Clonal Seed Orchard was evaluated for morphological and fodder characteristics at
the age of 8 years, which had started producing viable and quality seeds. The clones were evaluated
for qualitative characteristics such as mature plant growth habit, branching habit, stem shape, mature
stem colour, stem hardiness, leaf density, upper leaf surface, leaf blade size, colour of leaf, mature
fruit colour, fruit shape, seed colour, seed shape. Based on the observations on different
morphological parameters as well as cluster analysis, it was concluded that best clones for overall
morphological parameters were HA-4, SH-7, SI-7, SO-7 and CH-1. The best clones for fodder were
found to be CH-3, HA-2, HA-4, SI-7, SO-7 and SO-10. Furthermore, it was found that the best clones
for plant growth parameters were BI-3, HA-4, SI-7, SI-10, SI-15, SO-1 and SO-3, for leaf parameters
were HA-4, SH-7, SI-7 and SO-7 and best clones for fruit and seed parameters were BI-3, BI-4, CH-
1, CH-3, HA-3 and MA-2. Further, it can be concluded that some of the traits possessing high
heritability and genetic gain can be studied and exploited through various breeding programmes for
developing advanced generations through selection. Also, the clones having wide range of variability
offer scope for screening for desired traits that can be used for the selection of clones in order to
obtain better and improved planting material
