Effects of location, tillage and varieties on groundnut rust and leaf spot diseases in Mtwara, Tanzania

In Tanzania, groundnut leaf rust (LR) (Puccinia arachidis), early leaf spot (ELS) (Cercospora arachidicola), and late leaf spot   (LLS) (Cercosporidium personatum) diseases significantly reduce groundnut yields. This study aimed to determine the effects of location, tillage and variety on LR, ELS and LLS diseases. Location (Coastal zone (CZ), Coastal zone on station (CZ-OS), Eastern plateaux and mountain block...

Combining ability and maternal effects of QPM inbred lines for grain yield and other agronomic traits under low and optimum soil nitrogen environments

One of the objectives of plant breeding is the development of high-yielding varieties under stress and optimum environments using different methods of plant breeding. The study was conducted to estimate combining ability and maternal effects of quality protein maize (QPM) for grain yield and other agronomic traits under low and optimum soil nitrogen environments. Crosses of 11 QPM inbred lines with five hybrid checks...
