Effective Seed Yield and Flowering Synchrony of Parents of CIMMYT Three-Way-Cross Tropical Maize Hybrids
نویسندگان
چکیده
Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize production. The objective this research was to generate information on the production six hybrids their progenitors, adapted tropical lowlands. Data days to—and duration of—flowering, distance spike stigmas, five female single crosses male inbred lines were recorded for different combinations four planting densities sowing dates Mexico. effect density not significant. line T10 earliest highest T31 latest, occupying second place yield. T32/T10 T13/T14 had effective At date, females later flowering, accumulated fewer growing degree (GDD), obtained higher yields since grain-filling period coincided with hot cool nights. To achieve greater floral synchronization therefore seed, differential are recommended based from GDD each parent. classified according expected complexity flowering parents.

Grain yield stability of single cross maize (Zea mays L.) hybrids over three different environments
An investigation was conducted to determine the grain yield performance of seventy two single cross maize hybrids, their nine parents and one commercial check across three seasons (Summer, Kharif and Rabi) of the year 2006 at the Department of Millets, Tamil Nadu Agricultural University, Coimbatore. The design lay out was a randomized blocks design with three replications. The additive main eff...

Genetic improvement of Grain Yield by Determination of Selection Index in Single Cross Hybrids of Maize (Zea mays L.)
Selection based on proper selection indices can be one of the most effective methods for indirect selection of yield and yield components, simultaneously. In order to determination of selection index for improvement of maize yield, 60 single cross maize hybrids were planted in two separate experiments (drought stress and normal conditions) based on randomized complete block design (RCBD) with t...

This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
