The modified high protein maize hybrid knezha mvp 556


, : The modified high protein maize hybrid knezha mvp 556. Rasteniev"dni Nauki 23(11): 35-39

Data characterizing the modified single interlinear high protein maize hybrid Knezha MVP-556 are presented. The scheme of crossing with the general formula (A .times. A') .times. B was used in the hybrid's seed production. The latter is based on C type CMS or El Salvadore, applying the method of restoring fertility without manual detasseling of the female parents. Compared to the single hybrid, the seed yields of the presented one are 37% higher without irrigation. All approbation characters of the modified hybrid are close to these of the single hybrid Knezha VP-556. All positive economic characters of Knezha VP-556 are reproduced in the production of Knezha MVP-556, but under irrigation the grain yield of the latter is higher. Crude protein content in 100 g absolutely dry flour of the modified hybrid is 12.1% while cvs H-708, Knezha 530 and Knezha 510 have 9.9-10.0% crude protein content. According to reference data protein digestability and TDN of high protein maize cultivars are higher than these in common or high lysine maize. A wide extention of Knezha MVP-556 in practical production would provide opportunities for organizing more effective seed production, grain production and animal production, thus realizing a multiplicative effect.
