The total productivity of the high-yielding varieties was 110.6-124.8% higher than the standard variety. The varieties Tong, Podarok Moldovy, Bolgarsky 79, Pamir, Kaliforniyskoe chudo, PP10674, PP10678, D11000, D11520, S7103, whose productivity is almost equal to the standard variety, were also isolated. Their yield was 27,7-29,0 t/ha. In the hybrids of the first generation, the yield was slightly higher. Standard F1 Jaihun hybrid yield was 40,9 t/ha. This is a 145% higher result compared to the standard Dar Tashkenta variety. KEYWORDS Sweet pepper, repetition period, variety, hybrid, morphology, productivity. INTRODUCTION The homeland of pepper is considered to be the Mexican and Guatemalan countries of South America. From here it spread to Europe, Africa and South Asia. Sweet pepper fruit is rich in vitamins, mineral salts and dry matter. Its fruit surpasses all vegetables in terms of the formation of ascorbic acid (vitamin C). During the period when the fruit is technical, 100 g of the resulting mass contains 54-118 mg%, and when fully biologically Research Article RESULTS OF THE STUDY OF SETS OF SWEET PEPPER VARIETY SAMPLES AND F1 HYBRIDS IN THE REPEATED TERM Submission Date: December 07, 2022, Accepted Date: December 13, 2022, Published Date: December 17, 2022 Crossref doi: https://doi.org/10.37547/ajahi/Volume02Issue12-04 Rasulov Fakhriddin Fakhmuddinovich Phd Research Institute Of Vegetables, Melon Crops And Potato, ''Kuksaray'' Settlement, Tashkent District, Tashkent Region, 111106, Keles Str., Uzbekistan Journal Website: https://theusajournals. com/index.php/ajahi Copyright: Original content from this work may be used under the terms of the creative commons attributes 4.0 licence. https://doi.org/10.37547/ajahi/Volume02Issue12-04 https://scholar.google.co.in/scholar?q=RESULTS%20OF%20THE%20STUDY%20OF%20SETS%20OF%20SWEET%20PEPPER%20VARIETY%20SAMPLES%20AND%20F1%20HYBRIDS%20IN%20THE%20REPEATED%20TERM https://www.mendeley.com/search/?page=1&query=INHERITANCE%20OF%20GROWTH%20DURATION%20IN%20DOMESTIC%20AND%20INTERSPECIFIC%20F1%20PLANTS https://theusajournals.com/index.php/ajahi https://theusajournals.com https://doi.org/10.37547/ajahi/Volume02Issue12-04 https://doi.org/10.37547/ajahi/Volume02Issue12-04 Volume 02 Issue 12-2022 21 American Journal Of Agriculture And Horticulture Innovations (ISSN – 2771-2559) VOLUME 02 ISSUE 12 Pages: 20-26 SJIF IMPACT FACTOR (2021: 5. 705) (2022: 5. 705) OCLC – 1290679216 METADATA IF – 5.625 Publisher: Oscar Publishing Services Servi made, up to 368-535 mg% of ascorbic acid. In addition to vitamin C, there are vitamins A (carotene) – 4,60 mg, B1 (thiamine) – 0,06 mg, B2 (riboflavin) – 0,01 mg. Uzbekistan occupies a leading position in Central Asia in the cultivation of vegetables, melons and potato crops. The peculiarities of vegetable growing in our country are that there are opportunities to get two or more crops from one land in a year and to grow a crop of many crops very early by correctly selecting planting vegetable crops using natural climatic amenities wisely. This feature makes it possible to greatly increase the economic efficiency of farms now. This field has always been supported by our government [1, 4, 5]. Based on the data presented in the literature and the results of the experiments carried out by many researchers in various soil and climatic conditions with the aim of studying the influence of sweet pepper varieties, planting dates and schemes on yield, which are one of the main vegetable crops, they expressed their opinion as follows. DISCUSSION The catalog of varieties created in the regions of Central Asia and the post-Caucasian region based on the initial sources of the all-Caucasian Vegetable Center contains information about the valuable economic properties of sweet pepper 25 varieties of specimens. Including, in Kazakhstan, bayan Sulu, kozi Korpesh, Krasnoe chudo, Kaz-Thai varieties, in Kyrgyzstan 0636- 6007, VIO3170, rr0636-6056, avpp0408 lines, AVPP0912, AVPP1115, VIO3217, AVPP0911, avpp0108 lines, Nabat is in Turkmenistan, Shadlik and Sabo varieties are in Uzbekistan, Mili, Emily, Natalie, loshtak, Mira, Naridj in Armenia and Tayvanuri variety is in Georgia and and Khumai varieties are in Azerbaijan. This directory is home to varieties such as Sabo, Naridj, which turn yellow when physiologically ripe [3]. Volume 1 of the state register (2017), which allowed the application of selection achievements in the Russian Federation, included 742 varieties and hybrids of sweet pepper, of which 300 are F1 hybrids and 442 are varieties. In 2017 itself, it was allowed to plant 21 F1 hybrids and 19 varieties, a total of 40 varietal specimens. 94-95% of varieties and hybrids of sweet pepper are included in this register in the last 17 years from 2000, which means that there is an increasing demand for sweet pepper, its new varieties and hybrids from year to year [2]. In total, 41 sweet pepper varieties and hybrids were included in the State Register of agricultural crops recommended for planting on the territory of the Republic of Uzbekistan in 2017, of which 8 are varieties and 33 are hybrids. Of this, 8 varieties and 1 hybrids were created in our country, 19 belong to the Dutch, 7 French, 3 Italian, 2 Korean and 1 German breeding. In 2015, the list was 38, and in 2016 3 new foreign hybrids were included and 41, and in 2017 not a single variety and hybrid was included [6, 7]. RESEARCH RESULTS 28 samples of varieties of sweet pepper and 10 hybrids of F1 were studied by sowing in 2013-2014 in a repeated period. Dar Tashkent, Jaikhun F1, which included the State Register in Uzbekistan, was selected as the standard variety. Of the varieties and hybrids studied, 10 were created in Uzbekistan, 11 are samples from Italy, 2 from Japan, Holland, Spain, Turkey, South Korea, Russia, 1 from France, USA, Moldova, Germany. The study of the periods of development of varieties and hybrids studied in the iterative term and the duration of the growth period has a very important https://doi.org/10.37547/ajahi/Volume02Issue12-04 https://scholar.google.co.in/scholar?q=RESULTS%20OF%20THE%20STUDY%20OF%20SETS%20OF%20SWEET%20PEPPER%20VARIETY%20SAMPLES%20AND%20F1%20HYBRIDS%20IN%20THE%20REPEATED%20TERM https://www.mendeley.com/search/?page=1&query=INHERITANCE%20OF%20GROWTH%20DURATION%20IN%20DOMESTIC%20AND%20INTERSPECIFIC%20F1%20PLANTS https://theusajournals.com/index.php/ajahi Volume 02 Issue 12-2022 22 American Journal Of Agriculture And Horticulture Innovations (ISSN – 2771-2559) VOLUME 02 ISSUE 12 Pages: 20-26 SJIF IMPACT FACTOR (2021: 5. 705) (2022: 5. 705) OCLC – 1290679216 METADATA IF – 5.625 Publisher: Oscar Publishing Services Servi significance. After germination, 10-16 days were required for varietal specimens until the seedlings were germinated to the cover. Some varieties sprouted 3-4 days later than the standard variety. These include Emerald, Podarok Moldovi, Pamir, Cmorogd, Bulgarskiy 79, Californiyskoe chudo,, EC01- 144, C7103. Only two varietal specimens germinated one, two days before the standard variety C24177 and D11000. The period from the germination of seeds to the flowering of plants to the cover was divided into 2 groups (Table 1).

From the second group, the varieties Dar Tashkent, Zumrad, Nargiza, Sabo, Shodlik, Podarok Moldovi, Pamir, Maxi Bell, Californiyskoe chudo, Gampion, Smorogd, PP10678, EC01-044, C7103 took place. The same situation was observed in F1 hybrids. In the standard Jaihun F1 and El Real F1, Adriatico F1, Figaro F1, Dovras F1, Pkocraft F1 standings, it took 72-80 days from germination to germination to flowering to the top, while in the hybrids Donna F1, Vedrana F1, C30393 F1, C30414V F1, 70 days. The duration of the period or period of growth, from the germination of plants to the initial technical maturity of fruits, was 98-127 days in the studied varieties. When the yield of sweet pepper varieties and hybrids grown in the repeated term was determined, the highest yield was observed in the varieties Zumrad, Sabo, Yulduz, Shodlik, PP10676, D11200, D08018, and it was 31,2-35,2 t/ha. The total yield of varieties with high yields was 110.6- 124.8% higher than that of the standard variety.

This is 145% more than the standard Dar Tashkent variety. A slightly higher yield compared to the standard hybrid was observed in the hybrids Adriatico F1, Figaro F1, Vedrana F1, Dovras F1, Pkocraft F1 and amounted to 42,9-45,0 t/ha. This is a result of 104,9-110,0% more than a standard hybrid. Commodity yield amounted to an average of 89,2- 94,0% of the total yield. The best indicator in this is Dar Tashkent, D11200, D08018, Sabo, Yulduz, Shodlik, PP10676, Zarya Vostoka, 92,5 – 94,2% in Zumrad varieties, 92,5-94,7% in hybrids of the first generation Adriatico F1, Figaro F1, Dovras F1 and Pkocraft F1. According to observations, the non-commodity crop sweet pepper was 1,6-3,2 t/ha or 6,6-10,8% in varietal samples. In the first-generation hybrids, an indicator of 2,3-3,8 t/ha or 5,3-9,7% was recorded. The average yield of 5,8-10,8% compared to the total yield is certainly higher. There are several reasons for this, indicating the need for research in subsequent studies (Table 2).

The fruit of the standard dar Tashkent variety is conical, the color is light green during technical ripeness, the thickness of the fruit flesh was 3-4 mm. Such fruits are considered to be haridorgir in the domestic and foreign markets. Varieties whose fruit is conical, light green in color include: Nargiza, Yulduz, Lastochka, Podarok Moldovi, Gampion, RR10678, C24177, EC01-144. Of the hybrids of the first generation, the Jaykhun F1, Adriatico F1 were distinguished, which embodied such signs. In most hybrids, it was observed that the shape of the fruit was prismatic, the color was green, dark green. Many of these hybrids are brought from European Qualifications, and the demand for such varieties or hybrids in the domestic market of our country is not so great at the moment. However, the future demand for varieties and hybrids of this indicator will definitely increase. REFERENCES 1.
