Pea seed grade Nordman
New grain variety, characterized by increased drought resistance, less prone to rust and ascochitis in peas. High yielding, exceeded the Yamal standard in the CSI of the originator by 0,5-1,0 t / ga. Максимальная урожайность в 2011 sity 31,9 c ga pri 24,6 c / ga in standard. Intensive industrial type with high yield potential (4-6 т. s ga.), adaptability for cultivation and harvesting, characterized by high resistance to lodging, shedding and cracking of the bean, lined with ripeness and stem, grain and grain mowing areas of use.

Nordman is consistently in the group of leading varieties in terms of productivity, and exceeds the standard by 0,25-0,45 t / ga. Somewhat inferior in terms of lodging resistance to foreign varieties, will allow you to harvest it in a timely manner by direct combining.
The germination - ripening period was 76-90 days (mid-season 05 ripeness groups).
The variety was created by the method of intervarietal hybridization, followed by multiple individual and mass selection in cross-sowing of the hybrid combination Shtambovy mustache x Fitotron 1.
When selecting a new line, the commercial success of the predecessor was taken into account, similar in origin Yamal and Yamal varieties 2 our selection. Yamal during the last 5-6 years widespread in the region. Took up the square 45 thousand hectares in neighboring regions 9, 10 region. In pea crops in the Russian Federation it occupies 3-4 place by area in 2012-2015 yy. (more 300 thousand. ga). Producers deservedly consider it to be the best variety of the modern type of peas in the Russian Federation. .
Grain, with light pink white (or yellow) smooth rounded grain and light rib (weight 1000 горошин в среднем 214-245 g.), weakly prickly pea, leafless, mid-season (76-90 days. from germination to ripening). Non-crumbling due to difficult cracking of beans.
Weight 1000 seeds on average 20-50 sity. below, than standards and significantly lower, than many new varieties of this (grain) type. A medium-sized pea allows you to harvest it with a minimum level of crushing during harvesting and then reduce losses during seed processing. At the same time, the evenness and size of the peas meets the minimum requirements for the technological processing of food peas. There is an optimal balance between the size of a pea and yield (in particular, by selection by the pea filling index).
When forming the crop, the beans are multi-grain., contain 6-8 peas, on the plant usually 5-8 whole beans. At the recommended plant density for harvesting 80-90 PC. on 1 sq. m., biological yield is 3,5 – 6,0 t s ga. The beans are attached high-y 12-15 node. The formation of a powerful mustache creates a woven stalk, lodging resistant and suitable for direct combining.
The complex of features includes leaflessness with a powerful baleen leaf and the ability to interweave plants among themselves, low shedding when overstaying after harvesting and low cracking of peas, uniformity in size of peas, high bean attachment, makes it possible to harvest peas with minimal losses during direct combining (known, that losses during harvesting of leafy pea varieties reach 25-50% harvest).
Technological features of the cultivation of a new variety
Sowing rate reduced to conventional leafy varieties, but ensuring, taking into account field germination and plant survival, not less 750-800 developed plants per hectare. Usually required 1,1-1,25 million. viable peas per hectare when sowing with row and band seeders.
In the system of protective measures
– common herbicides for peas. Practice has shown high efficiency of Pulsar, ….
colewing insecticides (long-legged) and aphids in the first periods of growth. Re - for the generation of aphids, bruchus and moth
fungicides for poor prognosis of pea rust, ascochitis and other leaf infections
Main commercial advantages of the new variety
– stable and high yield, in the group of leaders in grain and green mass yield, allowing to obtain pea grain with a low cost
– high manufacturability due to moustached type of sheet, low crumbling, low level of seed cracking at an average weight 1000 peas in the range 210-240 sity.
– low level of grain loss during harvesting
due to manufacturability, unbroken stalk young sprinkling uncracking bean
low level of crushing of a pea (ideal shape and small size
also has a low level of crushing of a pea during part time work
What is the difference from the varieties with which it competes in the fields of farms –
differs from the Yamalsky variety in an earlier and more friendly ripening, more uniformity of the stem, more harvest, especially in dry years, and technological. More resistant to lodging. Has advantages in terms of grain quality - higher protein content in grain.
from mid-season variety Aksaysky 55, The idol of the widespread now has a higher potential yield, also has a smaller grain, not prone to cracking and shedding. more resistant to lodging and has a lower stem.
The broadest test of a new variety is proposed at the variety sections of the Russian Federation in 4, 7, 9, 10, 11, и др. регионах испытаний и в условиях производства.
