Studiul privind caracterele morfologice, ritmul de pierdere a apei din boabe și producția hibrizilor de porumb

Abstract

The paper presents a synthesis of investigations with 30 inbred lines of maize from different germplasm groups (BSSS, Iodent, Lacaune, Lancaster) and different maturity groups as parental forms. The research was carried out at the Institute of Crop Science „Porumbeni”, in the pedoclimatic conditions of 2022. As a result of topcross pollinations, hybrids from 6 maturity groups were obtained, which differ in morphological characters, productivity and the rate of water loss from the grains. Hybrids from the middle maturity group resulted in a higher productivity, compared to the hybrids from the other maturity groups. The rate of grain moisture loss for the hybrids from middle maturity group is more pronounced compared to early hybrids and is at the same level as late maturity group hybrids.
