Reynold Augustine Gonsalves (4 November 1928 – 16 February 2001), commonly known as Ren Gonsalves, was a Jamaican plant breeder, agricultural administrator, and racehorse trainer. He joined Jamaica's Banana Breeding Station in 1952, becoming senior plant breeder in 1969. His research into breeding bananas resistant to the fungal diseases that threatened their production in the region focused on Panama disease, yellow Sigatoka, and black Sigatoka.[1][2]
Over 15 years of work, Gonsalves developed the RG1 banana hybrid bearing his initials. RG1 was publicly reported in June 1996 and reported as resistant to race 1 of Fusarium wilt, a fungus responsible for Panama disease in bananas. RG1 underwent Belgian testing in 1996 and was reportedly distributed for evaluation in 2000 as a possible export banana with breeding material potential. Breeding history later places Gonsalves with Norman Simmonds and Kenneth Shepherd among major contributors to the foundations of modern conventional banana breeding.[3][4][5]
But Ren Gonsalves was not just a prominent botanical research scientist and agricultural operations manager. He also owned, bred, and trained racehorses, including winners of major Jamaican races. He served two terms as chairman of the Jamaica Racing Commission, and chaired the Betting, Gaming and Lotteries Commission from 1989 to 1991.[6][7]
Early life and education
[edit]Reynold “Ren” Augustine Gonsalves was born in Havana, Cuba, on 4 Nov, 1928. He was later naturalised Jamaican. His father, Raymond Alphonso Gonsalves, was a ship's engineer, and his mother was Annie Lee Pettigrew-Gonsalves.[1][2][8]
Gonsalves attended Donnington Primary School (Saint Mary), Happy Grove High School (Portland), and the Tutorial College (Kingston). He attended Howard University in Washington, D.C., where he studied for a Bachelor of Science degree, majoring in biology. A Howard commencement programme, dated 13 Jun, 1952, lists Reynold Augustine Gonsalves among its Bachelor of Science candidates.[1][2][9]
Banana breeding and administration
[edit]Ren Gonsalves joined Jamaica's Banana Breeding Station in 1952 as senior station master, according to INFOMUSA. He was appointed senior plant breeder in 1969. He became known in international banana research for breeding connected with Panama disease and yellow and black Sigatoka.[1]
Banana research in Jamaica began during the 1920s. The Banana Breeding Research Scheme was established in 1947. The programme was developed to improve diploid breeding parents and tetraploid hybrids. Later history describes 1960–1980 as an especially productive period. Gonsalves, Norman Simmonds and Kenneth Shepherd are identified as major contributors to the programme's scientific foundations.[4]
Ren Gonsalves participated in international conferences. He was active in INIBAP's regional network for Latin America and the Caribbean. He attended a regional meeting at Turrialba, Costa Rica, in 1986, and presented a paper entitled Reactions of Breeding Lines of Banana from Jamaica to Black Leaf Streak. He proposed a regional banana-breeding research project with its proceedings published in San José in 1987; paper pages: 218–228, and proposal pages: 232–235.[10][11]
According to Discover Jamaica, Gonsalves became general manager of the Jamaica Banana Board in 1986, which conflicts with the 1996 date claimed by INFOMUSA. A contemporary 1996 report described him as managing director, and described the organisation as regulating the industry while supporting research and production.[2][1][5]
The International Musa Germplasm Directory listed Gonsalves as director and curator of the Banana Breeding Station at Bodles. It is unclear whether this means that he directed the whole multidisciplinary Bodles Research Centre.[12]
RG1
[edit]RG1 is the best-known banana hybrid associated with Gonsalves and is a name reportedly deriving from his initials. Later breeding history classifies RG1 as a tetraploid (4 chromosome sets), while a 1996 report quotes Gonsalves himself calling it a triploid (3 chromosome sets). Multiple sources report its resistance to race 1 of Fusarium wilt.[4][3][13]
An IPS report published on Jun 24, 1996, recorded approximately 15 years of work on RG1. It was intended as a possible export crop, and as a base for breeding replacement varieties. The reported average yield was said to be six to seven hands per bunch, with a reported bunch weight of 35–40 kilograms. The development period and yield figures are attributed to a 1996 report.[3]
The RG1 plant material was sent to Belgium for tests intended to confirm its reaction to leaf-spot diseases. Results were expected in August 1996. More trials and a larger-scale production were contemplated. A 2000 workshop reported RG1 being distributed for evaluation and that concerns about yield had emerged.[5][3]
Scientific influence
[edit]Gonsalves's 1987 study examined reactions of Jamaican breeding lines to black leaf streak. Fullerton and Olsen cited it in a 1995 study of pathogenic variation in Mycosphaerella fijiensis. The current organism name has been used in later literature: Pseudocercospora fijiensis.[10][14]
Later reviews have used observations attributed to Gonsalves about host resistance in different locations. The cultivars discussed include Paka and Cook Islands. The research suggested that resistance expressed in one location may not remain effective against pathogen populations elsewhere. Gonsalves’s 1987 paper was cited in a 2025 study of quantitative resistance under controlled and field conditions.[15][16]
R. A. Gonsalves was the author of Advances of the Banana Board Breeding Scheme published in the proceedings of the San José workshop held from 28 March to 1 April 1989. The proceedings were published by INIBAP in 1990, pages 267–269. The paper is concerned with progress in the Jamaican scheme; it described diploid breeding that had begun about 30 years earlier; and highlighted difficulty combining disease resistance with commercial banana qualities.[17]
Horse racing
[edit]Ren Gonsalves was active as a racehorse owner, trainer, and regulator. He owned and trained Reca, ridden by George HoSang, and winner of the Governor's Cup in 1976, and also the Jamaica Derby in 1976. Reca was later commemorated through the Reca Trophy at Caymanas Park. Gonsalves also trained Silent Account, winner of the Jamaica 1000 Guineas in 1987.[18][19][20]
The Jamaica Observer lists Gonsalves as champion trainer in 1971 and 1972, while a historical Oaks table credits the following winners to him: Relentless, 1968; Symphony, 1969; Rhatid, 1971; and Charisma, 1973. A further historical table published in 2022 places Ren Gonsalves fourteenth of all time among Jamaican trainers, with a career total of 576 victories attributed to him in that table.[7][21][22]
Reynold Augustine Gonsalves served two terms as chairman of the Jamaica Racing Commission. He chaired the Betting, Gaming and Lotteries Commission, and was inducted into the Jamaica Racing Commission Hall of Fame as a trainer. Exact years of the two JRC terms and the Hall of Fame induction are awaiting official confirmation.[6][7][23]
Trainer Fernando Geddes identified Gonsalves as his “mentor”, stating that Ren was known at Caymanas Park as "The Magician". Geddes recalls that Gonsalves credited sustained work rather than special methods as the key to his successes.[24]
The Ren Gonsalves Memorial Cup runs during the JRC Hall of Fame meeting with a reported race distance of 2,000 metres. A race named the Reynold A. Gonsalves C.D. Trophy remained on the Caymanas Park card dated Jul 13, 2024.[25][26]
Honours and death
[edit]Reynold A. Gonsalves received the Commander of the Order of Distinction for his contribution to agriculture; he was a justice of the peace and a member of the Jamaica Society of Scientists.[1][2]
Gonsalves died from cancer in February 2001 at the age of 72. He was married with four sons and one daughter.[1][27]
