Interrelationship and Cause - Effect of Morphological Traits with Grain Yield and Oil Content among Indian Mustard (Brassica juncea L. Czern & Coss) Genotypes under Non- irrigated and Irrigated Condition | Chapter 11 | Advances and Trends in Agricultural Sciences Vol. 2
Water scarcity is a venomous upshot of
climate change and is one of the sternest factors restraining global crop
productivity. In order to study association and cause-effect of shortage in
irrigation on some morphological and quality traits on yield, an experiment
accommodating 20 genotypes of Indian
mustard (Brassica juncea L. Czern & Coss), was conducted in
Randomised Complete Block Design (RBCD) from various Rapeseed & Mustard
centres located across country, randomly
in three replications during Rabi
2016-17, one condition subjected to drought (devoid of irrigation) inside the Rainout shelter under residual moisture
condition and another situation with
normal irrigated field condition at research farm of Dr. Rajendra Prasad
Central Agricultural University, Pusa, Samastipur. Genotypic correlations for
grain yield and other characters were invariably higher than phenotypic
correlations indicating indicated less influence of environment. Earliness in
flowering (-0.010; -0.256) and maturity (-0.335; -0.185), Secondary branches
per plant (0.267; 0.169), Siliqua on primary mother axis (0.162; 0.079), Length
of primary axis (0.006; 0.275), Siliqua density (0.244; 0.189) and Biological
yield (0.444*;0.411*) also had shown positive correlation with grain yield per
plot at phenotypic level under both non- irrigated and irrigated condition
indicated that improvement in these morphological parameters indicated
genotypes with early flowering and maturity coupled with more secondary
branches with more siliqua accommodated
by longer primary mother axis with increasing density of siliqua along with
high biological yield and will ultimately enhance the grain yield.
