Araştırmada (Diyar 95 x ILC 482) melezinden gelen ve F4 kuşağına kadar bulk olarak ilerletilen nohut melez populasyonu, F4 kuşağında dört farklı tohum irilik sınıfına ayrılmış ve teksel seleksiyonla F8 kuşağına kadar bitki boyu, ilk bakla yüksekliği, bitkide dal ve bakla sayısı, bitki tane verimi ile 100 tane ağırlığına tohum iriliğinin etkisi gözlenmiştir. İncelenen karakterler yönünden generasyonlar arası ve tohum irilik grupları arası farklılıklar önemli bulunmuştur. İri tohumlular uzun boylu ve iri taneli, ancak dal ve bakla sayıları az ve bu nedenle düşük verimli olmuşlardır. Küçük taneliler ise verimli ancak Pazar değeri düşük küçük tohumlu olmuşlardır. İri tane seçimler ile iri tanelilik yakalanamamıştır.

THE EFFECT OF SELECTION ON YIELD AND YIELD COMPONENTS FOR SEED SIZE
IN CHICKPEA (Cicer arietinum L.)

Chickpea hybrid population, which has been derived from crosses Diyar 95 x ILC 482 and advanced until F4 generation by bulk, was separated to four different seed size-classes in this generation. Pedigri selection was used from F5 to F8, and seed size effecting plant height, first pod height, number of branches, pods and seeds per plant, seed yield per plant and 100 seed weight were evaluated. Differences among both seed size classes and generations were significant for all characters. The plants of large-seeded group grew up taller and produced larger seeds than the others, but this group gave less branches, pods and grain yield. Small-seeded groups had higher yields, but produced smaller seed with low market value. Large-seeded plants with high yield were not obtained by selection in this study.
