Genetics of Stay-Green Trait and Its Association with Leaf Spot Tolerance and Pod Yield in Groundnut
This study was designed to determine the genetic control of the stay-green trait and its relationship with leaf spot disease severity in groundnut. Results showed significant (p < 0.001) differences among the genotypes for early leaf spot (ELS), late leaf spot (LLS), leaf area under greenness (LAUG), SPAD chlorophyll meter readings (SCMR), and yield traits.
Modeling groundnut (Arachis hypogaea L.) performance under drought conditions
Erratic rainfall is often a limiting factor in the semi-arid regions where most groundnut cultivation occurs. Ensuring availability of cultivars that possess inherent tolerance to drought stress has become a priority. Field and box experiments were conducted under drought and non-drought conditions to identify physiological and agronomic traits correlated with pod yield.
