WEBVTT 00:00:07.079 --> 00:00:09.118 Have you ever walked into a grocery store 00:00:09.118 --> 00:00:12.559 and wondered where all those variety of apples came from? 00:00:12.559 --> 00:00:14.119 You might find SnapDragon, 00:00:14.119 --> 00:00:15.379 Pixie Crunch, 00:00:15.379 --> 00:00:16.599 Cosmic Crisp, 00:00:16.599 --> 00:00:17.531 Jazz, 00:00:17.531 --> 00:00:18.329 or Ambrosia 00:00:18.329 --> 00:00:22.489 next to the more familiar Red Delicious and Granny Smith. 00:00:22.489 --> 00:00:24.248 These delightfully descriptive names 00:00:24.248 --> 00:00:30.540 belong to just a handful of the over 7,500 apple varieties in the world. 00:00:30.540 --> 00:00:36.949 This huge diversity exists largely because of humanity's efforts to bear new fruit. 00:00:36.949 --> 00:00:41.248 Fruit breeding is a way to fulfill the expectations of farmers and consumers 00:00:41.248 --> 00:00:44.000 who seek specific qualities in an apple. 00:00:44.000 --> 00:00:49.290 On the one hand, farmers may want them to be disease-resistant and to store well. 00:00:49.290 --> 00:00:54.179 On the other, consumers are swayed by appearance, taste, and novelty. 00:00:54.179 --> 00:00:56.573 So, breeders have to consider everything 00:00:56.573 --> 00:00:59.076 from how well apples grow in certain climates 00:00:59.076 --> 00:01:02.616 to their color, taste, and size. 00:01:02.616 --> 00:01:07.813 And sometimes finding the perfect fit means breeding something new. 00:01:07.813 --> 00:01:11.333 To create apples with desirable characteristics, 00:01:11.333 --> 00:01:15.792 breeders first need to find parent apples that carry those characteristics. 00:01:15.792 --> 00:01:17.544 Once the parents have been selected, 00:01:17.544 --> 00:01:20.857 they have to wait until the trees bloom in the spring. 00:01:20.857 --> 00:01:23.991 The breeder takes the pollen from one bloom, called the father, 00:01:23.991 --> 00:01:28.641 and transfers it by hand to the other parent bloom, called the mother, 00:01:28.641 --> 00:01:31.622 through a process called cross-pollination. 00:01:31.622 --> 00:01:33.892 Once the mother bloom turns into an apple, 00:01:33.892 --> 00:01:36.812 the seeds are collected and then planted. 00:01:36.812 --> 00:01:40.884 It takes about five years for these seeds to grow into trees that produce apples, 00:01:40.884 --> 00:01:43.022 but because of the way traits are inherited, 00:01:43.022 --> 00:01:46.022 all of the seedlings produced will have different sets of genes 00:01:46.022 --> 00:01:48.142 and characteristics. 00:01:48.142 --> 00:01:50.312 This means that to achieve a desired quality, 00:01:50.312 --> 00:01:52.122 it takes a lot of offspring, 00:01:52.122 --> 00:01:55.772 not to mention patience on the breeder's part. 00:01:55.772 --> 00:01:58.662 When a seedling does bear fruit with the desired qualities, 00:01:58.662 --> 00:02:01.252 it's selected for further evaluation. 00:02:01.252 --> 00:02:04.071 Of the original crossed seedlings, 00:02:04.071 --> 00:02:08.401 about one in every 5,000 makes it to this prestigious stage. 00:02:08.401 --> 00:02:10.956 They're then sent to new farms 00:02:10.956 --> 00:02:14.022 where breeders can assess how various climates and soil types 00:02:14.022 --> 00:02:16.542 affect the plant's growth. 00:02:16.542 --> 00:02:18.773 The fruit of the seedling and its many clones 00:02:18.773 --> 00:02:22.531 must then be collected and sampled to ensure consistency. 00:02:22.531 --> 00:02:25.532 Breeders study about 45 traits in an apple, 00:02:25.532 --> 00:02:27.853 like the texture and firmness of the flesh, 00:02:27.853 --> 00:02:28.822 when it ripens, 00:02:28.822 --> 00:02:30.773 how sugary its juice is, 00:02:30.773 --> 00:02:32.693 and how long it stays fresh. 00:02:32.693 --> 00:02:36.444 Over several years, they weed out all the bad apples, 00:02:36.444 --> 00:02:40.253 selecting only those whose fruits are the best. 00:02:40.253 --> 00:02:43.522 These exclusive plants officially form the cultivar, 00:02:43.522 --> 00:02:46.074 or new apple variety. 00:02:46.074 --> 00:02:48.775 To ensure an exact copy of this cultivar, 00:02:48.775 --> 00:02:52.874 all apple trees must be grafted from the original seedling. 00:02:52.874 --> 00:02:55.185 Branches, called scion wood, 00:02:55.185 --> 00:02:59.551 are cut from the original tree and grown to generate more scion wood. 00:02:59.551 --> 00:03:02.775 Segments of these trees are then grafted onto root stalk - 00:03:02.775 --> 00:03:04.743 that's the lower section of another tree 00:03:04.743 --> 00:03:06.863 that's been chosen from a different cultivar 00:03:06.863 --> 00:03:10.254 for its superior roots and growing ability. 00:03:10.254 --> 00:03:12.967 Finally, this fusion creates a new apple tree 00:03:12.967 --> 00:03:15.323 with the desired qualities. 00:03:15.323 --> 00:03:17.684 Each new plant takes up to four years 00:03:17.684 --> 00:03:20.794 before it starts producing the fruit we eat. 00:03:20.794 --> 00:03:24.695 Apple breeding may be a difficult art, but it's accessible to all: 00:03:24.695 --> 00:03:26.327 universities, 00:03:26.327 --> 00:03:27.245 companies, 00:03:27.245 --> 00:03:30.044 and even individuals can create new cultivars. 00:03:30.044 --> 00:03:34.355 But to fully own an apple, the breeder faces a final challenge - 00:03:34.355 --> 00:03:36.905 naming the fruit. 00:03:36.905 --> 00:03:38.705 After a cultivar is patented, 00:03:38.705 --> 00:03:41.584 a breeder chooses a name for its trademark. 00:03:41.584 --> 00:03:46.336 That final step grants them long-lasting rights over the apple and its clones. 00:03:46.336 --> 00:03:48.468 That name must be completely original, 00:03:48.468 --> 00:03:51.456 and the catchier, the better, of course. 00:03:51.456 --> 00:03:55.325 With over 7,500 varieties and counting, 00:03:55.325 --> 00:03:57.705 that's why we have apples called Pink Lady, 00:03:57.705 --> 00:03:59.186 Sweet Tango, 00:03:59.186 --> 00:04:00.244 Kiku, 00:04:00.244 --> 00:04:01.996 and EverCrisp. 00:04:01.996 --> 00:04:05.057 The more we work with nature's bounty to breed new cultivars, 00:04:05.057 --> 00:04:09.746 the more creative and delectable these names will become.
