MORPHO-PHYSIOLOGICAL EVALUATION OF TURNIP

Abstract

Al though morphological characteristics of some Indian varietal populations
of turnip are known to some extent (Williams, 1985; Shrivastava, 1992), they
are not well studied. Therefore, one of the objectives of the present work was
to characterize and evaluate seven populations of turnip on the basis of their
morphophysiological characteristics. The populations which constituted the
material for present investigation are: Blue White (BW), Rose Red (RR), Purple
Top White (PT), Moddle White (MW), Golden Ball (GB), Early Snow Ball (SB),
and Green Globe (GG). To make comparative study the plants were raised
from the seeds in controlled condition in rows at a distance of 35-40 cm
during September-April, 1988-1989 in the field at Hazaribag. Following characteristics
were taken into consideration : per cent seed germination (PSG),
seedling morphology which included the mean hypocotyl length (MHL), mean
cotyledon area (MCA) and relative width of cotyledon (RWC %): number of
leaves/plant (MNL), lobes/leaf (MNLB),
