MAHALLIY "SHIRALI" VA "OLTIN VODIY" QOVUN NAVLARINING GENETIK XILMA-XILLIGI

Аннотация

Ushbu tadqiqot mahalliy Shirali va Oltin vodiy qovun navlarining genetik xilma-xilligini o‘rganishga qaratilgan. Tadqiqot natijalari navlarning morfologik va molekulyar xususiyatlari asosida genetik farqlilik va polimorfizm darajasini aniqlash imkonini berdi. Shirali navlari issiq va quruq iqlim sharoitlariga, Oltin vodiy navlari esa nam tuproq va o‘rtacha iqlim sharoitlariga moslashganligi ko‘rsatildi. Molekulyar markerlar va morfologik tahlillar yordamida navlarning irsiy barqarorligi, adaptatsion potensiali va hududiy moslashuvchanligi baholandi. Tadqiqot natijalari seleksiya, hududiy ekin strategiyasi va mahalliy qovun navlarini saqlashda ilmiy asos yaratadi. Shu bilan birga, genetik xilma-xillik kelajakda yuqori hosildor va ekologik barqaror navlar yaratish imkoniyatini oshiradi. Natijalar qishloq xo‘jaligi tadqiqotlari va mahalliy agrotexnologiyalarni rivojlantirishda muhim manba bo‘lib xizmat qiladi.

GENETIC DIVERSITY OF LOCAL SHIRALI AND OLTIN VODIY MELON VARIETIES Annotation. This study focused on the genetic diversity of local Shirali and Oltin vodiy melon varieties. The results allowed the assessment of genetic variation and polymorphism levels based on morphological and molecular characteristics. Shirali variety showed better adaptation to hot and dry climates, while Oltin vodiy variety adapted well to moist soils and moderate climatic conditions. Using molecular markers and morphological analysis, the study evaluated the varieties’ genetic stability, adaptive potential, and regional adaptability. The findings provide a scientific basis for breeding programs, regional cultivation strategies, and conservation of local melon varieties. Moreover, the genetic diversity of these varieties enhances the potential for developing high-yielding and environmentally resilient cultivars. The results serve as a valuable resource for agricultural research and the improvement of local agrotechnologies.
