The relationship between yield and yield components, such as "number of panicle per m2", "number of grain per panicle" and "1000 kernel weight", of rice was investigated in two yield trials (ÇVD-1 & ÇVD-2) in Diyarbakır during 1993 growing period.The results indicated that there was a significant positive correlation between "grain per panicle" and "grain yield" in ÇVD-1 but not in ÇVD-2.

Abstract

The relationship between yield and yield components, such as "number of panicle per m2", "number of grain per panicle" and "1000 kernel weight", of rice was investigated in two yield trials (ÇVD-1 & ÇVD-2) in Diyarbakır during 1993 growing period.The results indicated that there was a significant positive correlation between "grain per panicle" and "grain yield" in ÇVD-1 but not in ÇVD-2. Other correlation coefficients were insignificant, giving either positive or negative values in both trials.Simple linear and simple polynomial regression equations were found to be inadequate in explaining such relationships between each yield component and grain yield. Considering the yield potential of rice, multilinear regression equation in ÇVD-1 and multipolynomial regression equation in ÇVD-2 were found to be relatively adequate in explaining functional relationships between yield components and yield.

Özet

1993 ekim yılında Diyarbakır'da yürütülen 2 adet çeltik verim denemesinde "m2'de salkım sayısı", "salkımda dane sayısı" ve "1000 dane ağırlığı" gibi verim komponentleri verim ile verim arasındaki ilişkiler korelasyon doğrusal ve doğrusal olmayan regresyon metodlarıyla incelenmiştir.Buna göre salkımda dane sayısı ile verim arasında Çeltik Verim Denemesi-1'de istatistik! önemli pozitif ilişki saptanırken m2 de salkım sayısı ile verim arasında her iki denemede de önemsiz pozitif ilişkiler. 1000 dane ağırlığı ile verim arasında da önemsiz pozitif ilişkiler bulunmuştur. Verim komponentlerinin birbirleriyle negatif korelasyon ilişkileri içinde oldukları tespit edilmiştir.Basit doğrusal ve basit polynomial regresyon eşitlikleri verim komponentleri ve verim arasındaki ilişkileri açıklamakta yetersiz kalmışlardır. Çeşit Verim Denemesi-I'de (ÇVD-1) çoklu doğrusal regresyon eşitliği verimdeki potansiyel sınırlar içinde bu ilişkileri nispeten yeterli olarak açıklarken ÇVD-2'de ise çoklu polinomial regresyon eşitliği bu ilişkileri en iyi ifade eden eşitlik olmuştur.
