Genetic variability analysis for pseudo black chaff expression and yield traits among wheat (Triticum aestivum L.) genotypes

Abstract

Pseudo black chaff is associated with the presence of the stem rust resistance gene Sr2 in wheat. This trait is used as morphological marker for stem rust resistance. Genetic variability and correlation studies between PBC and other yield traits are important for assisting selection for stem rust resistance gene. Genetic estimates like heritability and genetic advance revealed that plant height has highest heritability (broad sense) and biomass has lowest. SPAD1 was found significantly negative correlated with PBC whereas Days to heading has positive significant correlation.
