Inheritance and combining ability study on drought tolerance and grain yield among early maturing inbred lines of maize (Zea mays L.)
Utilization of stress tolerant maize is key to sustainable production and food security. Limited knowledge on genetics of drought tolerance hampers development of drought tolerant varieties. The aim of this study was to study inheritance and combining ability of drought tolerance and grain yield among early inbred lines of maize. Five inbred lines were mated in full diallel in 2015 major season. The resultant 20...

Development of two high-yielding, consumer-acceptable apple banana hybrids (Musa species, AAB genome group) with resistance to Fusarium oxysporum f. sp. cubense race 1
Fusarium wilt of bananas (Musa species) is caused by Fusarium oxysporum f. sp. cubense (Foc). Foc race 1 in particular affects dessert bananas in Uganda, causing >60% yield loss. This study was conducted to assess the performance of two new apple banana genotypes for bunch yield, resistance to Foc race 1 and consumer acceptability. The new apple banana genotypes (NAMU1 and NAMU2), along with two check cultivars, one...

Effect of heat stress on common bean under natural growing conditions in three locations in different climate zones in the state of São Paulo, Brazil
Common bean (Phaseolus vulgaris L.) originated in medium to high altitude regions and is sensitive to high temperatures. Climate changes from an increase in global temperatures are foreseen, and therefore better understanding of the mechanisms of heat tolerance is necessary. In this context, the aim of this study was to investigate the effects of heat stress on twelve common bean genotypes under natural growing...

Genetic variation of tef [Eragrostis tef (Zucc.) Trotter] genotypes for reaction to tef shoot fly [Atherigona hyalinipennis Van Emden], at Maysiye, Northern Ethiopia
One of the major biotic stresses that limits tef yield is insect pests attack. Of these tef, shoot fly is sporadically important insect pest in various tef growing areas of Ethiopia. Evaluation of diversity of tef germplasm in Ethiopia for the reaction tef shoot fly might give a chance to get host plant resistance. The main objective of this study was to assess the genetic variation among tef genotypes for their...
