Research study on seed physical property of Mongolian wheat varieties

Wheat is the main vital cereal crop in Mongolia (Triticum spp.) The size of seed one important feature quality. It directly related to plant growth, yield, market factor and harvest efficiency [1]. Equally are shape seed. middle spike ripens fast, after which upper lower parts ripen. Even though seeds part fill up at same time as section spike, later. Seeds have good filling bigger too. Moreover, they plantlets. A two year study was conducted 2019-2020 determine effect on yield potential six wheat varieties, including such early maturing varieties (Darkhan-160, Darkhan-131), medium (Darkhan-34, Darkhan-212) late (Darkhan-144, Darkhan 181) varieties. Seed samples 6 were separated four groups diameter size, 2.0-2.2 mm, 2.2-2.4 2.4-2.6 2.6-2.8 mm respectively. seedling density 350 seeds/m2. field trial performed a completely randomized block design with 3 replications. 1000 kernel weight tillage stems grain fraction determined by using Grain Scan software.
 best qualified placed spike. Darkhan-181, Darkhan-131, Darkhan-34 reached 40-43 g Darkhan-144 variety had highest (40-47 g). portions different sizes significant among planted. longer vegetation period result higher portion larger compared short period. large (>2.4mm) increased from 41.6-46.85% 72.9-76.8% maturity (from medium). plots uniform both years. use largest resulted more competitive cropping system, improving yields 16.9%. decreased 4.9% planting (2.0-2.2 mm) smaller than control (2.2-2.4 mm). emergence yield. Results demonstrate that mid-large (>2.2mm >2.4mm) accordance properties useful production
