Abstract:
Knowledge of per se performance of parental lines and heterosis or outbreeding enhancement plays a crucial role for the breeding programs to develop competitive hybrids. Hence, this research was planned to assess the performances of QPM inbred lines and their single crosses; and estimate the magnitudes of mid-parent and better parent heterosis for grain yield and its components. Ten Quality Protein Maize parental inbred lines were crossed to produce 45 single crosses by using diallel mating design (Griffing Method-I, Model-II). The experimental material comprising of 56 (10 parental inbred lines, one check and 45 crosses) were evaluated in Randomized Block Design (RBD) with three replications. Analysis of variance showed that mean squares due to genotypes and per se performances of parents were highly significant for most of the traits studied. On the basis of per se performance for grain yield per plant three parental genotypes viz., TMT-TROP-(QPM), JP-25-W95 and CM-600 were identified as high yielding genotypes and three high yielding single crosses identified as POP-31Q-182Q11 X HKI-193-1, POP-31Q-182Q11 X TARUN-83-1-32 and TARUN-83-1-32 X CM-138. The highest mid-parent and better- parent heterosis for grain yield were obtained from POP-31Q-182Q11 X HKI-193-1 and TMT-TROP-(QPM) X TARUN-83-1-32 respectively. The results obtained in this study showed the promising potentials of the identified inbred lines and hybrids for further breeding of QPM for Vindhyan region of Eastern Uttar Pradesh.
