EVALUATION OF COMBINING ABILITY AND GRAIN YIELD OF SOME TROPICAL MAIZE INBRED LINES IN THE NORTH CENTRAL REGION OF VIETNAM
PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY,
Maize (Zea mays L.) is the second-largest annual crop after rice and is widely used for animal feed in the livestock and poultry industry in Vietnam. However, climate changes increase pests and disease infestation cause adverse impacts on maize productivity. Hence, generating new maize lines/varieties with high yield potential and resistance to pests and diseases is imperative work. The objective of this paper was to evaluate the combining ability, yield components and main abiotic and biotic stress tolerances of eight tropical maize inbred lines developed by single-cross for the North Central region. The results have indicated that 4 lines including D4, D8, D54 and D100, which attained high combining ability with the potential agronomic traits of interest. In the field trials, among the hybrid combinations, the D4 x D54 showed the highest yield potential by 7.47 tons/ha, followed by D8 x D54 (7.41 tons/ha) and the last (D100 x D54) was 7.34 tons/ha, exceeded 10.2% to 12.1% on the average and was higher than the yield of control DK9901 variety. Those inbred lines have shown good agronomic characteristics, adaptability, yield stability and acceptable abiotic and biotic stress tolerances for the maize cultivating areas in the North Central of this country.
