Analysis of grain yield stability and assessment of genotype × environment interaction for grain sorghum (Sorghum bicolor L. Moench) genotypes
The interaction of genotype × environment creates complications in yield prediction and is a challenge for agronomy and plant breeding programs. To evaluate grain yield stability and genotype × environment interaction for 18 local and exotic grain sorghum cultivars, lines, and hybrids, a field experiment was conducted using randomized complete block design with three replications in four region...
متن کاملResponse of millet and sorghum to a varying water supply around the primary and nodal roots.
BACKGROUND AND AIMS Cereals have two root systems. The primary system originates from the embryo when the seed germinates and can support the plant until it produces grain. The nodal system can emerge from stem nodes throughout the plant's life; its value for yield is unclear and depends on the environment. The aim of this study was to test the role of nodal roots of sorghum and millet in plant...
متن کاملAnatomical response of grain sorghum roots to Meloidogyne incognita acrita.
The cotton root-knot nematode, Meloidogyne incognita acrita, reproduced on the roots of grain sorghum, causing syncytia in the cortex or stele of lateral roots. Giant cells developed either singly with few nuclei or in groups with many nuclei. Giant cells that developed in groups appeared the same as those which developed singly. The pericycle and endodermis were interrupted at the site of nema...

An approach based on a linear rate of increase in harvest index Deficiencies in the HI approach, however, may be (HI) with time after anthesis has been used as a simple means to predict grain growth and yield in many crop simulation models. When associated with use of a constant rate of HI increase applied to...
متن کاملEvaluation of grain yield in sorghum hybrids under water stress.
Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grown in a randomized block design experiment, with three replications. T...
