Temperate maize lines

Genetic diversity provides the capacity for plants to meet changing environments. It is fundamentally important in crop improvement. Fifty-nine local maize lines developed at INERA and 41 exotic (temperate and tropical) inbred lines were characterized using 1057 SNP markers to (1) analyse the genetic diversity in a diverse set of maize inbred lines; (2) determine the level of genetic diversity in INERA inbred lines and patterns of relationships of these inbred lines developed from two sources; and (3) examine the genetic differences between local and exotic germplasms.

The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and yield related traits. Eight inbred lines were crossed with three testers using line × tester mating design. The resulting twenty-four crosses along with eleven parents were evaluated at two locations during Kharif 2015 in a complete randomized block design.

Thirty genotypes of Maize which included twenty eight inbred lines and two checks maintained at D(K)ARS, SKUAST-K were used for the study carried out in the Department of Crop Physiology, University of Agricultural Sciences, GKVK Bangalore. In this programme the genetic variability for Epicuticular Wax Content (EWC) was studied. The data of the experiment revealed a significant genetic variability in epicuticular waxes among the germplasm lines of maize. Accordingly, the EWC ranged from 1.56 (KDM-921A) µg/cm2 to 7.54 (KDM-954) µg/cm2 with a mean of 4.25 µg/cm2 .

A QTL mapping study for maize resistance to the Mediterranean corn borer (MCB) was performed with a RIL population derived from the cross B73 × CML103. To develop commercial inbreds of maize resistant to the MCB for use in Europe, it would be useful to transfer resistance from tropical germplasm like the subtropical inbred CML103 to temperate lines.

Breeding for cold tolerance in maize promises to allow increasing growth area and production in temperate zones. The objective of this research was to conduct genome-wide association analyses (GWAS) in temperate maize inbred lines and to find strategies for pyramiding genes for cold tolerance.
