An eminent Plant Breeder of International repute was born in a small village, Gudavalli in Guntur Dist. of Andhra Pradesh. He obtained his Bachelors, Masters and Doctorate degrees from the Banaras Hindu University with outstanding merit.
He started his career as a Lecturer in Banaras Hindu University and entered ICAR as a Scientist through Agricultural Research Service In which he ranked first in the country, before joining the ANGRAU as Associate Professor in 1981.
He had a very fruitful and illustrious career as a Plant breeder and developed a number of vegetable and pulsed varieties which have revolutionized production in various niches, before his retirement from ANGRAU as Director of Extension.
His contributions to the farming community are of an immense value. During his illustrious career he held many key positions in the university.
Even after his retirement he is very active in developing high yielding and disease resistant varieties, hybrids of field crops as well as vegetable crops, in addition to educating farmers on sustainable agricultural practices
His untiring work as Pulse Breeder has resulted in the development 30 high yielding pulse varieties (10 Black gram, 7 Green gram, 8 Red gram, 3 Bengal gram and 2 Horse gram). With the adoption of these improved varieties and location specific production technologies under rice fallows, the overall area, production and productivity of Black gram in AP have increased from 2.7 lakh ha to 5.25 lakh ha., 0.97 lakh tones to 3.7 lakh tones and 397 kg/ha to 906 kg/ha respectively. This sustainable technology resulted in a tremendous positive impact on farmer’s economy on long term basis.
The impact was assessed by an independent agency, as an additional income of over Rs.360 crores in 1989 which is equivalent to over Rs.4000 crores (at current prices) annually to the state, apart from creating rural employment of 10 lakh additional man days.
This sustainable rice-pulse system is now under threat by the Yellow Mosaic Virus disease. His post retirement (2009-13) research has resulted in the development of 3 YMV resistant black gram varieties viz., Sri, Nandi and Maruti and a green gram variety Amulya, which are suitable for rice fallows and are expected to bring back sustainability to rice-pulse system.
For this outstanding work, he was honoured with two National Awards ( Hooker award, 1999 and ISPRD award 1994).
Chickpea, a cold loving crop, was not even a minor crop prior to 1985 in AP due to short winters,terminal moisture and heat stresses. With his untiring efforts, in collaboration with ICRISAT,in developing and popularization of short duration varieties, the situation reversed and AP became the leading state in chickpea productivity. The Chickpea area increased 5 fold during 198 -2008 from a mere 1.2 ha. to 6.38 lakh ha., Productivity doubled from 750 kg to 1468 kg/ha. And 10 fold increase in production 0.9 lkh MT to 9.37 lakh MT. Andhra Pradesh now has the distinction of surplus of this protein rich pulse crop.
The economic impact of this achievement is enormous and needs to be documented as a success story which is worth several thousand crores of additional income to the farmers and the State annually.
For this outstanding contribution he received two International awards viz., ‘King Baudovin Award,’ and ‘Dooren Margaret Mashler Distinguished Achievemnts Award,' during 2002.
Beans are protein and minral rich delicious vegetables. In order to make them yield round the year, he worked relentlessly and developed novel Bush Dolichos varieties and high quality French bean varieties. A French bean variety ‘Arka Komal’ developed by him was officially declared during 1985 as a National variety. An impact study conducted by the Economists of IIHR, Bangalore during 2003 found that 84% of the market arrivals of French beans are of ‘Arka Komal’ indicating its importance in the economy of vegetable growers for three decades.
The Bush Dolichos varieties are his creation and made the availability of Dolichos beans round the year a reality. They fit in various cropping systems and help farmer to realize higher returns in a shorter period.
For his work on beans he received two National Awards (Hooker Award 1999, AICRP on Vegetable crops Award 2010) and National Fellowship on vegetables by ISVS 2012.
SRI is a sustainable, low input, cost effective production technology which was introduced and standardized by him India. Through Mission mode approach he demonstrated the potential of SRI technology to farmers and was appreciated at many national and international fora. Food security Mission of Govt. of India adapted this technology to increase food production in the country in a sustainable manner to produce more rice with less seed, water and other externally purchased chemical inputs. SRI has become popular in many states.
Soybean has now become the life line for farmers in northern districts of Telangana.
1. Principal Scientist Pulses (1985 – 1995): Under his leadership the Pulses Research work in AP was rated as the best in the country by the ICAR for this period.
2. Associate Director of Research, RARS, Lam (KG Zone, 1995 – 2000): NAARM rated the performance of RARS, Lam as most satisfactory under difficult situations based on the impact analysis during his tenure as ADR.
3. Director of Extension, ANGRAU (2000 – 2005): Developed lead programs like e-extension, database development, reorganization of extension education into DATTC’S etc. which prompted the Director General, ICAR, to declare ANGRAU as a model for Extension Education to all SAU’s.
4. He held the full time additional charge for the posts of:
Director of Research ( 2002 ),
Dean P.G. Studies ( 2003 ),
Dean Veterinary sciences ( 2003 ),
Director of Research (Animal Sciences) ( 2001 ) and
Comptroller of ANGRAU ( 2004 to 2005).

Developed new plant types of Black gram (sympodial and main stem bearing) and Green gram (multicluster and cereal mimics) and worked out their inheritance.
Mechanism and genetics of resistance to preharvest sprouting in Mungbean
Sources of resistance to various diseases and their inheritance have been worked out in different pulse crops viz., Yellow Mosaic Virus disease, powdery mildew, wilt, corynespora in black gram, angular black leaf spot and powdery mildew in Green gram and rust in Cowpea and Dolichos
The inheritance of YMV disease in Black gram was deciphered as governed by two independent dominant genes acting in complementary fashion and developed three YMV disease resistant varieties suitable for round the year cultivation.
Genetics of yield and yield components and their environmental interactions in Green gram, Black gram, Red gram, Cowpea, French bean, Dolichos, Cotton, Chillies have been estimated through quantitative genetic analysis and published.
An auto tetraploid was developed through gamma irradiation in Mungbean and a true breeding tetrasomic line (2n=22+2) was isolated in Mungbean which is resistant to sucking pests.
Employed Reverse breeding technique and developed varieties of Chillies, Marigold. Water melon which are better than the hybrids, thus made available seed at low cost to the farmers.
Genetic Resources Collected, maintained, evaluated , utilized and catalogued germplasm lines of Black gram (560), Green gram (476), French beans (1061), Red gram (347), Bengal gram (161), Dolichos (270), Cowpea (226), Other legumes (87), Soybean (172), Chiilies (188), Okra (219), Maize(139), Sesamum(80).
