Abstract
ABSTRACT
The present investigation entitled “Evaluation of Lepidium sativum Linn. strains
under mid hill conditions of Himachal Pradesh.” wascarried out in the experimental field and
Laboratory of the Department of Forest Products, College of Forestry, Dr. Y S Parmar
University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2012-13 & 2013-14. In
the first experiment “Morphological and yield Studies” morphological features and yield of
all the eight germplasm accessions were recorded for plant height, main shoots/ plant, no. of
lateral branches/ plant, leaf characteristics, aerial biomass/ plant, aerial biomass (kg/ ha),
main root length, dry root yield, seed yield and 1000 seed weight. All the eight germplasm
accessions showed differences in morphological details with regard to basal and middle leaf
shapes. On the basis of apical leaf shape, all the germplasm accessions evaluated were found
to be uniform in shape. On the basis of maximum plant height, fresh and dry aerial biomass
yield and main root length, MLS-1007 appears to be better in comparison to all other
evaluated accessions. In second experiment “Phenological and Floral biology studies” days to
initiation of flowering, 50% flowering stage and full flowering stage days after the seed
sowing were recorded. No inter-accessions difference in floral biology was noticed amongst
the eight accessions evaluated and the type of dichogamy present in its flower is protogyny.
In the third experiment “Pollination studies” two different pollination treatments (open and
self pollination) were studied by using t-test. Observations recorded were seed yield/ plant,
seed germination percentage and 1000 seed weight. The species was found to favour self
pollination (about 85%). In fourth experiment “Meiotic studies” the species was found to be
diploid with 2n=24 with normal meiosis and 88.53% pollen stainability.
