HERITABILITY AND GENETIC ADVANCE FROM SELECTION FOR MORPHOLOGICAL, BIOCHEMICAL AND ANATOMICAL TRAITS

Abstracts

The present investigation aimed at estimating heritability in broad sense (h2b) and genetic advance (GA) from selection for agronomic, physiological, leaf amino acids and anatomical traits of quinoa (Chenopodium quinoa Willd.) under elevated water stress. A two-year experiment was conducted in a split plot experiment with five replications. The main plots were devoted to three irrigation regimes, i.e. well irrigation (WI), moderate irrigation stress (MIS) and severe irrigation stress (SIS), achieving a field capacity of 95, 65 and 35%, respectively, and sub plots to five quinoa genotypes. For agronomic and physiological traits, h2b ranged from 0.0% for inflorescences/plant (IPP), 1000-seed/plant (TSW) and seeds/plant (SPP) under WI, plant height (PH) and IPP under MIS to > 97.0% for root length, inflorescence length and seed yield/plant under all irrigation treatments.
