Current genetic research on groundnut in India

Abstract

The progress in genetic improvement of groundnut in India during the last five decades has been possible largely due to understanding and utilizing the information generated on the genetics of various characters of the plant. The current genetic studies on groundnut in India are carried out both on qualitative and agronomically important quantitative characters. Research accomplishments which are noteworthy in these areas have been reported in this paper. However, the genetics of several characters of economic importance has not been analyzed so far. Efforts to incorporate resistance to abiotic and biotic factors have gained momentum and a large number of resistant sources have been identified for each of these constraints. Additional efforts are expected to be made on gaining insight into the genetics of resistance to abiotic stresses and insect pests among biotic stresses, where the available information is meagre. Future studies are also expected to concentrate on unravelling the relationship of economic yield with various other characters, including the physiological and biochemical ones. Molecular marker techniques hold promise for genetic analysis of groundnut, as in other crop plants.

Colored polyethylene film mulches on weed control, soil conditions and peanut yield

“…Polyethylene (PE) film mulching can conserve soil moisture and raise soil temperature (Dong et al 2008), promote growth and increase yields (Li et al 2004, Dong et al 2009). In peanut production, clear plastic film is the most commonly used, however, higher temperature under the clear mulch during pod development may restrict pod and kernel growth (Reddy et al 1988), and weed control also could be a problem (Waterer 2000), which will reduce the pod yield. During the last decade, many industries have developed a variety of colored plastic films for mulching, which have additional benefits related to altered quantity and quality of reflected light into the plant canopy (Andino and Motsenbocker 2004), and have the effect of regulating the environment, suppressing weeds, controlling crop growth and pests and diseases (Bond andGrundy 2001, Mahajan et al 2007).…”

Economic and Academic Importance of Peanut

“…Most agronomic traits in peanut are inherited quantitatively and are highly influenced by genotype  environment interactions. The genetics of several important target traits in peanut have been studied and this information is well documented (Reddy and Murthy 1996;Nigam 2015).…”
