Early life and education
Born into a farming family in Waitara in the Taranaki, Yeates attended Stratford District High School (where he won an Entrance Scholarship (later called the University Entrance Scholarship)) and then Victoria College (now Victoria University of Wellington, then part of the University of New Zealand) in Wellington. He completed a B.Sc. and then a M.Sc in Botany with first class honours. He obtained a Jacob Joseph Scholarhsip.
He then completed the first PhD from the University of New Zealand
He was also an active member of the Victoria College Tramping Club, having Yeates Peak and Yeates track in the Tararua Range named after him.
He left for Trinity College, Cambridge, where he studied chromosomal counts in plants, starting in 1925. He returned to New Zealand in July 1927 and was awarded his Trinity College PhD in 1931, having completed his research in parallel with his teaching commitments at the newly created Massey College (now Massey University, then also part of the University of New Zealand) outside Palmerston North.
Academic work
His early research was on New Zealand flax/Phormium tenax (Māori: harakeke), which at the time was used extensively as fibre for ropes and cloths. One of the key centres for production was the delta of the Manawatu River, but Yeates travelled extensively looking for quality cultivars which he grew on the Turitea campus. Flax had long been used for textiles (see Māori traditional textiles) and it was correctly guessed that the best cultivars were to be found adjacent to historical sites of textile-making. The Great Depression of the 1930s caused serious damaged the commercial flax industry in New Zealand and it never recovered.
Some of the flax worked involved chromosome counting, which he had previously done in his thesis work. The flax Ngaro was found to have 32 rather than the normal 24 chromosomes.
Later research involved "farm forestry", a movement to introduce trees onto farms for the benefit of livestock, pasture and crops and as a source of income.
He was the founding head of Agricultural Botany at Massey and this was his core teaching area. In 1954 he, with E. O. Campbell, published Agricultural Botany, a textbook based on this teaching.
Plant breeding
Yeates was a foundation member of the New Zealand Rhododendron Association in 1944 and also its some-time Secretary-Treasurer. He was also crucial in the founding of the national garden of the association (now "Heritage Park") at Kimbolton (which is close to his home in Palmerston North, but has better soil and climate for rhododendron). He was also active in the introduction and breeding of azaleas, rhododendrons and Lilium hybrids.
Lilies
Lilium auratum and Lilium speciosum were first crossed in the 1860s, but then not again until the 1950s by Yeates and Leslie Jury in New Zealand.
The name Melford Hybrids was used for his lily crosses, which he bred initially at his property on Long Melford Rd, in Palmerston North. His cultivars include:
