New Varieties of Pulses and Their Special Characteristics!

Proteins essential for human nutrition are largely obtained from pulses. However, pulse production in our country was not sufficient to meet the demand, leading to the import of required pulses. In the past five years, however, domestic production has increased to meet the needs of our population, reducing the need for imports. This increase is attributed to farmers cultivating high-yielding and disease-resistant new varieties.

Historical Development of Pulse Varieties in Tamil Nadu

The necessity for developing new varieties of pulses in Tamil Nadu increased post-1900 due to the growing population and the need to increase food production. Initially, new varieties were created using the mass selection method. However, due to inconsistent yield performance, plant breeding techniques involving hybridization and selection were adopted.

Most pulse crops being self-pollinating necessitated the adoption of pure line selection methods initially. Significant improvements were made post-1950, with the introduction of new varieties of pulses using methods like induced mutation and hybridization. The pedigree method of breeding, which involves hybridization of two superior varieties and subsequent selection for desired traits over generations, became prevalent.
