Nagcarlang Tomato type from the Philippines.

The description of the Nagcarlang tomato type which follows has been made up in part from information given by Dr. Eugenio E. Cruz, Director, Bureau of Plant Industry. Manila, Republic of the Philippines and from Dr. Howard Peto, Peto Seed Company, Saticoy, California. The Nagcarlang tomato is the only type which will set fruit in high humidity areas throughout the Philippines. For this reason, during the winter of 1948--49, Dr. Peto called at Manila to see if the Nagcarlang tomato type could be used in a breeding programs so that a canning tomato for the Philippines would result. He also took tomato varieties, over to Mindanao and the Southern Philippines,of which Kolea and Anahu have proven adaptable.
Under Ontario greenhouse condition the flowers of Nagearlang are open in type and the pistils are exposed. As a result one must place pollen on the pistils if pollination is to take place. In the tropics high insect activity possibly carries out cross polination.
The Nagcarlang type has come into Ontario in two shipments. The first seed obtained has been written up in Scientific Agriculture 32:57-66, 1952. As far as is known the only surviving member in breeding programmes of the first shipment made to Ontario in 1948 is the type known as Philippine #2. Dr. Eugenio E. Cruz forwarded Nagcarlang to Guelph in the second shipment made in 1959, this seed having been gathered at Laguna in the Philippines.
In the Philippines Nagcarlang is known to be a wild-type tomato. Its history is unknown. It is not a variety as no two plants are alike. It is simply a heterozygous form which has survived in the jungles of the Philippines and which has also been brought under cultivation and even sold commercially. Dr, Peto has verbally stated that in the Philippines the Nagcarlang type has survived-and become pollinated in areas with 100 inches of rainfall per season. He stated that it ia hard to believe that such wild-type fruit could be sold commercially. However, he saw Nagcarlang fruits being sold when he visited the open market in Manila. He noted that the flowers hang down, shed the water, and do not experience as much blossom drop rainy weather as is experienced by commercial types.
While no two Nagcarlang plants are the same there are points in common. For example, practically all Nagcarlang fruits are small, very rough. and with a purplish "muddy" fruit colour. The fruits are firm and under Ontario conditions flat and sweet in flavour. They mostly ripen late in the season. The plants are very robust, and dense with healthy foliage. While Dr. Peto attributes fruit set under humid conditions to the flowers, the fact that the pollen remains active may have a chemical basis as the plants and fruits of the Nagcarlang type have a distinct purplish colour.
In the Philipyines the Nagcarlang tomato is resistant to disease and to periodic drought. In Ontario it is tolerant to late blight. Under Ontario conditions it will set fruit at temperatures as low as 45 deg. F, which is 10 degrees below the point at which tomatoes normally set fruit. In other words, it is cold tolerant, It is interesting to note that in the tropics Nagcarlang is resistant to sterility caused by damp conditions and in Ontario, far removed from-the tropics, it is resistant to sterility caused by cool conditions.
In the tropics the point of interest in to see if, through a breeding programs, the bridge can be gaped between the wild Nagcarlang type and the commercial varieties found on the North American continent. This would allow the commercial canning of tomatoes to be carried out in certain tropical areas such as the Philippines, where high humidity makes this difficult at the present time.
