Abstract
Aim:
The present investigation was designed to evaluate 150 diverse germplasm of
Indian mustard along with five checks for seed yield and attributing traits.
Methodology: A total of 150 genotypes of Indian mustard were
evaluated in Augmented Block Design along with five check cultivars (Kranti,
Maya, Pusa Bold, NPJ-112, RGN 73) in five blocks. Data were collected for 16
different quantitative traits on each genotype.
Results:
ANOVA revealed significant differences between genotypes for all traits
studied. Seed yield plant-1 had significant and positive correlation with
most of the yield contributing traits. For seed yield/plant, 15 accessions
(DRMR-1722, BDJ-I-538, DRMR-4, JMG-113, DRMR-681, DRMR-1849, DRMR-1697,
DRMR-1610, DRMR-1996, DRMR-107, DRMR-1588, DRMR-1379, DRMR-1995, IB-26, DRMR-2116)
were significantly superior over best check.
Interpretation: The present study was found useful for
identification of diverse genotypes of Indian mustard for different yield
attributing traits. The promising lines will be utilized in Indian mustard
breeding for improving seed yield and oil content.
Key words: Brassica juncea, Correlation, Genetic
diversity, Indian mustard, Variability
