Genetics of Leaf Water
Potential and its Relationship with Drought Avoidance Components in Rice (Oryza sativa L.)
Abstract:
Leaf water potential (y leaf)
was measured in culture solution in hydroponic system under controlled
condition of the two crosses involving diverse rice genotypes to investigate
the inheritance pattern and heritability. Polygenes were involved in this
trait and theψleaf was governed
either by no-dominant or partial dominant alleles and that was controlled by
genes with additive effects in upland and hill rice. The heritability
estimates were low (25-28%). Leaf water potential was significantly and
positively correlated with root thickness, root volume, root length, plant
height and leaf area in one of the two crosses. Negative relationship was
found with shoot dry weight.
