Daha önce tane özellikleri yönünde toplu seleksiyona tabi tutulmuş heterojen bir kumdarı (Panicum miliaceum L.) populasyonunda iki seleksiyon birimiyle beş tarımsal özellikte azalan ve arları yönde toplu seleksiyon uygulanmıştır. Kontrol populasyon ile toplu seleksiyon uygulanan populasyonların mukayesesi, seleksiyon etkisinin asimetrik olduğunu göstermiştir: ortalama ve varyansdaki değişme negatif yönde uygulanan seleksiyonda pozitif seleksiyona nazaran çok daha belirgindir. Toplu seleksiyon uygulanan populasyonlarda görülen asimetrinin seleksiyonla populasyon ortalamasındaki değişmeye bağlı olarak varyansın değişmesi ve gen frekansının eşit olmamasından kaynaklandığı kanısına varılmıştır. Populasyonların bütün özellikler bakımından arzu edilen yönde iyileştirilmesine, önemli özelliklerin birlikte dikkate alınmasının en yaradı seleksiyon kriteri olduğu belirienmiştir.

Mass selection for increased and decreased expression of five agronomic characters using two selection units was conducted in a heterogeneous population previously mass selected for seed characteristics of proso millet (Panictim miliaceum L.). Mean comparison between the unselected control and mass-selected populations showed asymmetrical response to selection; the shift in means and variances in undesirable direction being much greater than in desirable direction. It seemed that scaling effect and unequal gene frequencies were responsible for the asymmetry observed in the population studied. Overall selection was the most promising selection criteria in regarding overall desirability of the populations.
