Bu çal›flma, sekiz yerf›st›¤› genotipinde generatif büyüme, tohumda ya¤ ve protein birikimi ile baz› verim unsurlar›n› belirlemek amac›yla 2001 ve 2002 y›llar›nda yürütülmüfltür. Genotiplerin generatif geliflimlerinin bafllamas›ndan sonra periyodik say›mlarla çiçek, ginefor ve meyve say›lar› belirlenmifltir. Meyve tutumundan sonra 15 gün aral›klarla her parselden alt› bitki hasat edilerek, tohumlardaki ya¤ ve protein oranlar› belirlenmifltir. Yetiflme dönemi sonunda genotiplerin ürettikleri toplam çiçek, ginefor ve meyve say›lar› belirlenerek, çiçeklerin ginefora ve meyveye dönme oranlar› ile gineforlar›n meyveye dönme oranlar› hesaplanm›flt›r. Ayr›ca hasat sonunda genotiplerin baz› verim unsurlar› ve meyve verimi belirlenmifl, generatif büyüme parametreleri ile meyve verimi aras›ndaki korelasyonlar hesaplanm›flt›r. Çal›flma sonucunda, generatif büyüme özelliklerinin genotiplere göre önemli derecede de¤ifliklik gösterdi¤i saptanm›flt›r. Oluflan çiçek say›s›n›n, çiçeklerin ginefor ve meyveye dönme oranlar› ile negatif iliflkili oldu¤u, ancak çiçeklerin ginefora ve meyveye dönme oranlar› ile meyve veriminin pozitif iliflkili oldu¤u belirlenmifltir. En yüksek tohum verimi, toplam çiçek say›s› en az ancak çiçeklerin meyveye dönme oran› en yüksek olan Osmaniye 2005 çeflidinden elde edildi¤i saptanm›flt›r.Genotiplerde ya¤ birikimi genelde benzer e¤ilim göstermifl ve ilk olgunlaflma dönemine (R7) kadar h›zl› bir art›fl görülürken, daha sonra fizyolojik olum dönemine (R8) do¤ru azalma göstermifltir. Protein birikimi ise genel olarak tüm genotiplerde fizyolojik olum dönemine kadar sürekli bir art›fl göstermifltir.

This study was conducted to evaluate reproductive growth, oil and protein accumulation in seeds, and some yield components of 8 groundnut genotypes in 2001 and 2002. The number of flowers, pegs, and pods per plant during the reproductive period were determined with periodic counts starting from flowering. The percentage of flowers turned to pegs and pods, and the percentage of pegs turned to pods were calculated at the end of the growing period. After pod setting, 6 plants per plot were harvested at 15-day intervals to determine oil and protein content of seeds. At final harvest pod yield and some yield components were determined, and correlations between reproductive growth parameters and pod yield were calculated. Genotypes had significantly different reproductive growth parameters. Total number of flowers per plant was negatively correlated with the percentage of flowers turned to pegs and pods, whereas the percentage of flowers turned to pegs and pods was positively correlated with pod yield. The highest pod yield was obtained from cv. Osmaniye 2005, which had the lowest number of flowers per plant and the highest percentage of flowers turned to pods. The results of the current study showed that percentage of flowers turned to pegs and the percentage of pegs turned to pods were the most promising generative plant characteristics that could contribute to seed yield increase in groundnut production in a typical eastern Mediterranean climate. Seed oil content of the groundnut genotypes increased rapidly until initiation of first maturity (R7) and then declined in the later growth stages, whereas protein content generally increased gradually until physiological maturity (R8) in all genotypes.
