Genetic analysis of earliness components in some bread wheat genotypes [electronic resource].

Includes reference.

The main objectives of this investigation were to study the inheritance of earliness traits in wheat, (Triticum aestivum L.) also to evaluate and study some early and late mature parents and their resulted crosses. This investigation included eight bread wheat parental genotypes differed in their earliness components. Half diailel cross was made between these genotypes. The eight parents and their 28 F1 crosses were planted in two sowing dates, early and normal. The collected data were analyzed using Griffing 1956 procedure, Method 2, model 1.The collected data of this experiment were days to first node emergence, days to booting, days to heading, days to anthesis, days to maturity, grain filling period and grain filling rate.
