Seeds of good quality were 10 mm in length and 3 mm in width. The number of flowering
spikes, that is, potential seed productivity (PSP), was 84.3 grains, the number of grains (RSP)
was 29.01, and the yield was 29.01%. The weight of one thousand grains was 30.0 g when
weighed.
H.spontaneum S. Koch, collected from hills of Akhangaran district of Tashkent region. One-
year-old plants were used naturally. The number of races per 1 m2 area was 14.
The average length of the stalks of the stalks was 20.5 cm and the number of cobs in the stalks
was 58.8 ± 4.30 (Fig. 1). It was found that the spike in the spike was 7 to 16.4 cm in length.
Seeds of good quality were 10 mm in length and 3 mm in width. The number of flowering
spikes, that is, potential seed yield (PSP), was 19.6 ± 1.43 grains, the number of grains (RSP)
was 18.5 ± 1.62 grains, and the percentage of grain yield was 30.1 ± 0.3. (Figure 2).
From the above data, the highest rates of actual seed productivity (RSP) are H.spontaneum S.
Koch. planted in the Botanical Garden (29.01) and in the cultural barley Navasadsky-525 (28.1).
The lowest values are H.spontaneum S. Koch. (18,5) and the barley in the Kyzyl-Kurgan type
(24.2). However, it should be noted that the potential seed yield (PSP) of the studied species and
varieties is nearly identical (3.0 ± 0.01) and that the true variability of the above-mentioned
differences indicates the specific capabilities of these plants. When weighing one thousand
grains, weighing 28.9 ± 0.28 g. It was.
The total length of the cob on the stem of Navasadsky-525 varieties of cultural barley was 20.7
cm on average (Figure 3). The number of cobs in the spike was 88.2 ± 2.66. The number of
flowering spikes, that is, potential seed yield (PSP), was found to be 29.4 ± 0.89 on average. The
number of cereal grains (RSPs) was recorded at 28.1 ± 0.72. The percentage of grain in cobs was
29.9 ± 0.58 (Fig. 4).
The weight of one thousand grains was 49.9 ± 0.2 g. Navasadskiy-525 varieties thous. Grain
weight H.spontaneum S. Koch. weighing twice as much as the type.
Compast grade total length of the stalks was 21.4 cm and the number of cobs on the heads
averaged 87.6 ± 1.25 units (Figure 5). The number of flower bulbs (PSP) was found to be 25.2 ±
0.32. This indicator is the same as that of H.spontaneum S. Koch and Navasadsky -525. Cereal
grains were 27.2 ± 0.39 grains, cereal grains were 10 mm, and grain was 4 mm.
Grain percentage
(%) in cobs was recorded at 31.1 ± 0.41 (Figure 6).
The weight of one thousand grains was 50.04 ± 0.12 g. Compast grade on this sign is also
H.spontaneum S. Koch. weight twice as much as the type.
Comander grade total length of the stalks was 21.4 cm, mean number of cobs in the heads was
82.5 ± 3.01. The number of flower bulbs (PSP) was found to be 25.2 ± 0.32. This indicator is the
same as that of H.spontaneum S. Koch and Navasadsky -525. Cereal grains were 24.7 ± 1.04
grains, length of cereal grains was 10 mm, and grain width was 4 mm. Grain (%) in cobs was
recorded at 30.1 ± 0.32.
The weight of one thousand grains was 51.04 ± 0.14 g. Compast grade on this sign is also
H.spontaneum S. Koch. weight twice as much as the type.
The weight of the most promising Kyzyl-Korgon variety was 1000 seeds (32.3 g).
