The aim of this study was to determine certain characters, having significant effect in seed yield and protein content by statistical analyze methods, conditional formatting, correlation and path, multiple linear stepwise regression, factor, biplot, decision tree and phyton regression analyzes in bread wheat. This study was carried out under arid conditions in the experimental field of the Faculty of Agriculture of ESOGU during the cultivation period of 2019-2020 and 2020-2021. In the study, seed yield, heading day, plant height, seed number and weight/spike, spike length, SPAD, chlorophyll a and b, thousand seed weight, test weight, protein content, micro sedimentation were examined. The two-year averages of the results of the examined elements were taken into account and statistical analyzes were made on these results. As statistical analyzes; conditional formatting, correlation and path, multiple linear stepwise regression, factor, biplot, decision tree and phyton regression were used. It was determined that seed number/spike, seed weight/spike, micro sedimentation, SPAD, chlorophyll a and chlorophyll b were were found to be effective parameters on seed yield and protein content.

Keywords: Bread wheat, genotype, yeld and quality components, conditional formatting, correlation and path, multiple linear stepwise regression, factor, biplot, decision tree and phyton regression analyses

Bu çalýþmanýn amacý, ekmeklik buðdayda tane verimi ve protein içeriði üzerinde önemli etkiye sahip olan bazý karakterlerin istatistiksel analiz yöntemleri, koþullu biçimlendirme, korelasyon ve yol, çoklu doðrusal kademeli regresyon, faktör, biplot, karar aðacý ve fiton regresyon analizleri ile belirlenmesidir.. Bu çalýþma 2019-2020 ve 2020-2021 yetiþtirme döneminde ESOGÜ Ziraat Fakültesi deneme alanýnda kurak koþullarda yürütülmüþtür. Çalýþmada tohum verimi, baþak günü, bitki boyu, tohum sayýsý ve aðýrlýðý/baþaðý, baþak uzunluðu, SPAD, klorofil a ve b, bin tane aðýrlýðý, test aðýrlýðý, protein içeriði, mikrosedimantasyon incelenmiþtir. Ýncelenen unsurlarýn sonuçlarýnýn iki yýllýk ortalamalarý dikkate alýnmýþ ve bu sonuçlar üzerinden istatistiksel analizler yapýlmýþtýr. Ýstatistiksel analizler olarak; koþullu biçimlendirme, korelasyon ve yol, çoklu doðrusal aþamalý regresyon, faktör, biplot, karar aðacý ve fiton regresyon kullanýlmýþtýr. Tohum sayýsý/baþak, tohum aðýrlýðý/baþak, mikrosedimantasyon, SPAD, klorofil a ve klorofil b'nin tohum verimi ve protein içeriði üzerinde etkili parametreler olduðu belirlendi.

Anahtar Kelimeler: Ekmeklik buðday, genotip, verim ve kalite bileþenleri, koþullu biçimlendirme, korelasyon ve path analizi, çoklu lineer kademeli regresyon, faktör, biplot, karar aðacý ve python regresyon analizi
