چکیده مقاله :
The purpose of this study was to investigate the advantages and disadvantages of Participatory Plant Breeding (PPB). Seventy-six breeders were randomly selected from among 95 breeders who were working at the Seed and Plant Improvement Institute, Karaj, Iran. Data were collected by a questionnaire as the main data collection instrument. The face and content validity of the questionnaire was approved by a panel of agricultural extension and plant breeding experts. The reliability of the questionnaire was calculated and it turned out to be high, ranging from 0.83-0.92. The descriptive findings of the study suggested that the breeders had generally positive perception toward using PPB. The correlation analysis results showed that there is a positive and significant (p>0.01) correlation among the levels of familiarity with PPB, advantages, and breeders’ perception toward the use of PPB. In addition, there was a negative and significant (p>0.01) correlation between breeders' perception of the disadvantages faced by PPB and their perception of using participatory plant breeding. Finally, stepwise regression analysis indicated that the advantages and disadvantages of PPB explained about 58% of the variations in breeders’ perception toward using PPB.
هدف این پژوهش بررسی مزایا و معایب به­کارگیری به­نژادی مشارکتی بود. 76 به­نژادگر از بین 95 به­نژادگر موسسه تحقیقات اصلاح بذر و نهال کرج، به عنوان نمونه مورد مطالعه به طور تصادفی انتخاب شدند. داده­ها از طریق پرسشنامه به عنوان ابزار تحقیق گرد­آوری شده است. روایی ظاهری و محتویی پرسشنامه توسط پانلی از متخصصان ترویج و آموزش کشاورزی بازبینی و تایید شد. پایایی پرسشنامه بین 83/0 تا 92/0 بدست آمد. یافته­های توصیفی پژوهش نشان دادند که به­نژادگران ادراک مثبتی درخصوص به­کارگیری به­نژادی مشارکتی داشتند. نتایج آزمون همبستگی نشان می­دهد که همبستگی مثبت و معنی­داری در سطح خطای یک درصد بین سطح آشنایی با به­نژادی مشارکتی، مزایا و ادراک به­نژادگران نسبت به به­کارگیری به­نژادی مشارکتی وجود داشت. هم­چنین همبستگی منفی و معنی­داری در سطح خطای یک درصد بین معایب به­نژادی مشارکتی و ادراک به­نژادگران درخصوص بکارگیری آن وجود داشت. نتایج حاصل از تجزیه و تحلیل رگرسیون به روش گام به گام نشان داد که دو متغیر مزایا و معایب به­کارگیری به­نژادی مشارکتی، در مجموع 58 درصد از تغییرات ادراک به­نژادگران درخصوص به­کارگیری به­نژادی مشارکتی را تبیین می­کنند.
