biotic and abiotic stress

1. BIOTIC ND ABIOTIC STRESS
BREEDING IN JUTE
B. MOHANAPRIYA

2. Jute
• GENUS - Corchorus
FAMILY - Malvaceae (formerly under Tiliaceae)
• Jute is also called the golden fiber for its
color and high cash value.

5. C. capsularisis C. olitorius
comparatively more
resistant to flood and
drought
tolerant to diseases and
pests, produces the
stronger commercial fiber
susceptible to diseases
and pests
Susceptible to drought

6. Breeding methods
TRADITIONAL
• Introduction
• Selection
• Interspecific Hybridization
• Backcrossing
• Mutation
MODREN TECHNIQUES
 Marker assited selection – to find out
the putative Qtl
 Gene pyramiding
 Marker assisted back cross breeding
 Qtl introgression
 Agrobacterium mediated
trasformations
 Protoplasmic fusion - overcome the
barrier of sexual incompatibility

7. WILD SPECIES BIOTIC AND ABIOTIC
SOURCE
C. depressus C. asplenifolius,
C. cinerascens, C. erinoceus, and
C. erodiodes
- higher degree of drought tolerance
C. trilocularis , C. tridens
tolerance to
water
stagnation.
C. urticifolius and C. psuedo-
capsularis
resistant reaction to all diseases
including root rot, stem rot except soft
rot and anthracnose ,
C. urticifolius,
C. pseudo-capsularis, and C. pseudo-
olitorius
moderately resistant to root-knot
nematode,
Meloidogyne incognita
C. junodii, C. pinnatipertitus, C.
saxatilis, and C. gillettii
potent
sources of biotic stress resistance

11. Future trust
Therefore, molecular genetics and biotechnology
in jute in combination with conventional breeding
and other areas will guide future research for
improving quality and productivity of Corchorus
with enhanced biotic and abiotic stress tolerance.
