Evaluation of Helicoverpa and drought resistance in desi and kabuli chickpea

Abstract

A chickpea collection of 1600 desi and 1400 kabuli were evaluated for yield losses arising from pod borer (Helicoverpa armigera) infestation under rainfed conditions by spraying half the plots to prevent pod borer infestation and allowing the other half to be infested. From these lines, 82 were selected for further detailed evaluation of Helicoverpa resistance and drought resistance under irrigated and rainfed conditions. The yield losses from Helicoverpa damage varied from 10 to 33% depending on the chickpea type and the growing environment. Spreading types were more susceptible to Helicoverpa damage than erect types, as were kabuli types compared to desi types. Yield losses due to Helicoverpa infestation were always greater in the irrigated than in the rainfed materials. Terminal drought reduced yields by 13-37% depending on plant type. The yields in the kabuli chickpea lines were more severely reduced than were the desi types, due to a greater reduction in the number of branches and pods per plant in the kabuli compared to the desi lines. It appears that the extent of pod borer damage varies between the chickpea types, and that desi types have greater drought resistance than kabuli ones. These characteristics should be informative for the population improvement of chickpea for environments in which terminal drought and Helicoverpa damage occur frequently.

An optimal protocol for in vitro regeneration, efficient rooting and stable transplantation of chickpea

“…Chickpea is well known to be susceptible to flooding and excess moisture (Yadav et al, 2006). Under high moisture condition chickpea is prone to fungus and wilt diseases (Yadav et al, 2006). During the present investigations, we did not find autoclaved soil mixture in any way to be an essential requirement for the establishment of in vitro raised plantlets of chickpea.…”

“…of India) in the ratio of 1:1:1 ( Figure 3B) is most suitable for achieving cent percent transplantation success. Chickpea is well known to be susceptible to flooding and excess moisture (Yadav et al, 2006). Under high moisture condition chickpea is prone to fungus and wilt diseases (Yadav et al, 2006).…”

“…Instead we realized that improving aeration/porosity of potting mixture by mixing sand is highly beneficial. Chickpea grows best on fertile sandy, loam soils with good internal drainage (Yadav et al, 2006). Good drainage is necessary because even short period of flooding, water logging soil, moisture reduces growth and increases susceptibility to root and stem rots and heavy rainfall season shows reduced yields due to disease outbreaks and stem lodging problem from excessive vegetative growth (Yadav et al, 2006).…”

Evaluation of Different Integrated Pest Management Modules to Control Helicoverpa for Adaptation to Climate Change

“…Yadav et al (2006) also reported resistant genotypes of chickpea both against H. armigera and drought. Similarly, significant interaction was found between drought and genotypes of soybean for herbivores (Helicoverpa zea and Spodoptera exigua) (Grinnan et al, 2013).…”

In vitro regeneration and induction of multiple shooting in Cicer arietinum L. using cotyledonary nodal explants

“…Chickpea is well known for its vulnerability to flooding and excess moisture. Also under high moisture conditions, chickpea is prone to fungus and wilt diseases (Yadav et al, 2006). Ascochyta blight disease is a major disease seen in chickpea, affecting the yield about 50-80%.…”
