Phosphorus (P) sources are limited around the globe making it unsustainable with present farming practices. This necessitates the development of more phosphorus efficient crops while monitoring P status. Groundnut (Arachis hypogaea L.) is a major crop in Southern Andhra Pradesh, India where soils are light textured and less fertile. Twenty groundnu...
Correlation analysis provides useful information for basis of selection for trait like pod and seed y ield. Seed yield is the most economic as well as very complex character in nature because it is governed by polygene and greatly influenced by environmental factors.

Hybridization followed by selection in segregating generations is the main mode of varietal development in self-pollinated crops like groundnut. Before making crosses, it is important to know which of the parents are going to nick well and yield desirable segregants in terms of yield and other desirable attributes aimed at. There are different mati...
