Maternal effects, reciprocal differences and combining ability study for yield and its component traits in maize ( L.) through modified diallel analysis.

Combining ability status of the inbred lines is crucial information for hybrid breeding program. Diallel or line × tester mating designs are frequently used to evaluate the combining ability. In the current study a modified diallel model was used, wherein the Griffing's combining ability effects were further partitioned to understand the effects due to maternal and reciprocal.

Sustainable intensification of climate-resilient maize-chickpea system in semi-arid tropics through assessing factor productivity.

Global trends show that the rapid increase in maize production is associated more with the expansion of maize growing areas than with rapid increases in yield. This is possible through achieving possible higher productivity through maize production practices intensification to meet the sustainable production. Therefore, a field experiment on "Ecological intensification of climate-resilient maize-chickpea cropping system" was conducted during consecutive three years from 2017-2018 to 2019-2020 at Main Agricultural Research Station, Dharwad, Karnataka, India.

Frequency of heterotic hybrids in relation to general combining ability of parents in sweet corn.

The success of developing prominent hybrids directly depends on the selection of parents with good combining ability which can transfer desirable genes with additive effects to their progeny. The data of 42 hybrids generated using 7 × 7 full diallel design; their seven parents along with three check hybrids were subjected to combining ability analysis from the experiment that was carried out during rainy season 2019. The analysis of variance showed significant general combining ability, and specific combining ability mean sum of squares for all the thirteen characters studied.

First report of Fusarium verticillioides causing Pokkah boeng disease on maize in India.

Maize is a widely grown cereal crop in India and ranks third to wheat and rice in production (https://iimr.icar.gov.

Productivity, nutrient use efficiency, energetic, and economics of winter maize in south India.

The winter maize area is rapidly spreading in south India in response to rising demand from the poultry and fish feed industries due to the absence of major environmental constraints. Further farmers' are using the winter environment to expand maize area and production. Hence there is immense potential to increase the area under winter maize cultivation.
