The Malling Merton series is related to Apple Rootstocks.
The Malling series is a group of rootstocks for grafting apple trees. It was developed at the East Malling Research Station of the South-Eastern Agricultural College at Wye in Kent, England.
In 1912, Ronald Hatton and his colleagues rationalized, standardized and catalogued the various rootstocks.
Their first list had nine rootstock varieties, assigned the "type" numbers I - IX. The list later grew to twenty-four and the Roman numerals gave way to Arabic numerals with the prefix "Malling" or "M". From about 1917, a collaboration between East Malling and the John Innes Institute, in Merton Park in Surrey, gave rise to the Malling-Merton series, which were resistant to Eriosoma lanigerum, the woolly apple aphid.

The tag colour of the truthfully labeled seed (TFL) is Opal green. The size TFL seed is 15 cm × 10 cm.
It is the category of seed produced by private seed companies and is sold under truthful labels. Companies should maintain field and seed standards suggested for quality seed production as per the seed act.
Truthful labeling is compulsory for notified kinds of varieties. Quality is guaranteed by producing agency. Applicable to notified kinds only. Applicable to both notified and released varieties. It should satisfy both minimum field and seed standards.

The black rot resistant cabbage variety is Pusa Mukta.
Black rot is a bacterial disease that affects crucifers. The bacterial pathogen, Xanthomonas campestris PV. campestris is particularly damaging to cabbage and cauliflower.
The black Rot-resistant cabbage variety "Pusa Mukta", is a hybrid of EC-10109 and EC-24855 varieties. The plants of this variety produce compact, slightly flat heads, with a short stalk and light green leaves with wavy margins. The average yield of the variety is 30 - 35 t/ha.

The seed production method followed in cabbage for higher seed yield is the Stump method.
When the crop in the first season is fully matured, the heads are examined for true to type. The plants with off-type heads are removed. Then the heads are cut just below the base using a sharp knife, keeping the stem with the outer whorl of leaves intact.
The beheaded portion of the plant is called the 'stump'. The stumps are either left in situ or replanted in the second season. By this method, the crop matures 12 - 15 days earlier.

Potato tuber moth pest of potato attacks the tuber in both field and storage.
It is the most widely distributed potato insect in the world. It is usually found in warm climates for overwinter survival and is considered a subtropical pest. The moth or worm is considered the most serious pest of potatoes in tropical and subtropical regions.
Foliar injury in the field is due to the larvae (tuber worm) mining into leaflets, causing them to form transparent blisters, then move into stem tissue causing death.
PTM/PTW damage is yearlong as the PTM will continue to breed in storage and lay eggs which will hatch into PTW. The length of the life cycle will depend on the storage temperature.

Bougainvillea variety with variegated foliage is Thimma.
Bougainvillea thimma Botanically known as Bougainvillea spectabilis thimma from Nyctaginaceae family. This is an evergreen shrubby vine, popular for its long-lasting, colourful flower bracts which appear periodically throughout most of the year.

The new Seed Policy was launched in on 16^th September, 1988.
The National Seed Policy 2002 was launched to provide intellectual property protection to new varieties; usher this sector into planned development; protect the interest of farmers and encourage the conservation of agrobiodiversity.
The aim of providing the farmer with the best planting materials available in the world is to increase productivity and thereby increase farm income and export earnings.

Almost all vegetables belong to the sub-community Spermatophyte.
Spermatophyte also known as phanerogam is any plant that produces seeds, hence the alternative name seed plant. Spermatophytes are a subset of embryophytes or land plants.
Seed-bearing plants almost all vegetables and fruits are a subclade of the vascular plants (tracheophytes) and were traditionally divided into angiosperms or flowering plants and gymnosperms, which include the gnetophytes, cycads, ginkgo and conifers.
