Palamarchuc V. Evaluation of self-pollinated lines of maize for the creation of hybrids suitable for mechanic cultivation and harvest

Study of various characteristics of suitableness for mechanical cultivation of self-pollinated and simple hybrids of maize was carried out. Classification of self-pollinated lines and simple hybrids according to firmness of lateral wall of the stem is submitted. For estimate to stand breeding material maize resistant to lodging of the use dynamic instrument, which allow install to stand by firmness of the stem lateral wall. The effects of combination capability and genetic components of the lines dispersion according to the characteristics "height of ears is strengthening" and "lateral wall firmness" were established. Self-pollinated lines with high firmness of lateral wall, resistant to lodging, optimal height of strengthening of not hanging ears, on the ground of which new hybrids, suitable for mechanical cultivation were created, were singled out. Main principles of parent couple selection for crossbreeding aiming at obtaining hybrids with the mentioned above characteristics were formulated.
