Identification of New Sources for Earliness and Low Grain Moisture at Harvest through Maize Landraces’ Test-Cross Performance

نویسندگان

چکیده

Early maturity is a highly important factor in the interrelations between yield, grain moisture, and plant density, contributing to cost-efficient maize production. Landraces conserved gene banks present promising basis for enriching diversity of early breeding material. To start speed up mobilization genetic resources maintained ex situ Maize Research Institute Zemun Polje bank collection, which are currently scattered, little studied, underused, 63 landraces were selected as new potential sources maturity; their test-cross performance with two divergent testers was evaluated. The majority prevailed flint type (29) exhibited heterosis yield when crossed Iowa Stiff Stalk Synthetic—Iowa Dent tester (102NS), out 20 top crosses expressed moisture below defined threshold value (21.1%). best performing can be used starting point pre-breeding programme broadening In parallel, nine simultaneous (14NS), exhibiting above value. A heterotic effect inbred implies existence an independent pool. These findings will contribute material low at harvest, goals breeding.

Identification of sources for drought tolerance in local bread wheat landraces

In order to identify drought tolerant germplasm, 97 bread wheat landraces, mostly Iranian genotypes, were evaluated in two separate experiments of normal and drought stress conditions in the field of Agriculture and Natural Resources Research Center of Varamin. The experiments were performed in lattice statistical design with three replications. Drought conditions in the stress experiment was e...

Effects of pre-harvest application of parquat on grain moisture reduction, grain yield and quality of rapeseed (Brassica napus L.) cultivars

Pre-harvest desiccation of rapeseed crop may allow a more timely harvest as well as increase the speed and harvest operation efficiency as a second crop after rice. An effective desiccant which could be used as a harvest-aid with no negative effects on rapeseed yield and quality would be advantageous for oil seed crop producers and may reduce yield losses with no interferential effects on rice ...
