From this Institute, some noteworthy varietal release in the 50 years of research in Agricultural / Horticultural crops include five paddy varieties (MDU 1 to 5), one black gram variety (MDU 1), one Kolingi variety (MDU 1) and in Horticultural crops MDU 1 in Brinjal, Snake gourd, Bitter gourd, Crysanthemum and Marigold to suit to the need of southern Tamil Nadu farmers. Moreover researchers are in pipeline for the pre-release rice culture ACM 01010 and cluster bean IC 432117.
The special characteristics of these varieties are MDU 1 drought and cold tolerant for Ramanathapuram District farmers, MDU 2 and MDU 4 cold tolerant varieties released for Cumbum valley farmers,MDU 5 is short duration and tolerant to terminal stress.

Development of short and medium duration rice varieties, rice varieties suitable for aerobic situation, moderately shattering and early mutant in ADT ® 47 rice, MDU 1 black gram variety was released in the year 2014. It is high yielding (790 kg/ha), matures in 70-75 days. Besides yield it has good batter quality, large bold pods and suitable for cultivation in rabi season. Black gram variety with yellow mosaic virus resistance, superior battering quality black gram genotypes, high yielding white seeded sesame variety and barnyard millet have been attempted at this Institute. Moisture stress management in cotton, influencing of mulching and anti transpirants on soybean are some research frontiers. Besides, research is also carried out on the development of tonic to enhancing yield and quality of banana as well development of seaweed liquid fertilizer to improve productivity in Agricultural ecosystem.
Recently research has been extended to Gingelly,Pulses,Brinjal , Tomato and other minor pulses like soyabean , mochai etc.
Krishi Vigyan Kendra, at Agricultural College and Research Institute, Madurai was established in 1971 as Farmers Training Centre by the District Agricultural Department.
