There are two types of flowers, and usually only one of these, known as the sessile spikelet
(SS), is fertile, according to the study.
At this stage, temperatures below 17[degrees]C negatively impact pollen grain formation (SOSBAI, 2014), resulting in increased spikelet
sterility in this period (Baruah et al.
17 cm), tillers number m-2, spikes number m-2, spike length, number of spikelet
spike-1, number of grains spike-1, 1000-grain weight, grain yield, straw yield, biological yield and harvest index, respectively, in both seasons followed by Zn foliar application followed by Mn foliar application followed by Fe foliar application then Cu foliar application.
The maximum spikelet
per spike was found where the wheat was sown @ 150 kg ha-1 that was also comparable with 125 kg ha-1 treatment while the minimum was in 100 kg ha-1 (Table 2).
After harvest, spikelet
per main spike (SMS, the 10 main panicle average the value), grain number per spike (GrNo/S, the average value of the random 10 ears), sterile spikelet
number (SSNo, the average value of the random 10 ears), thousand grain weight (TGW, 1000 grain weight), harvest index (HI) and grain yield per plot (GY/P) were investigated.
1) may consist of many spikelets
arranged in a complex branching system, or a few spikelets
or even a single spikelet
(Haines & Lye, 1983, Vegetti & Tivano, 1991a; Vegetti, 1992, 1994, 2002, 2003; Heinzen & Vegetti, 1994; Goetghebeur, 1998; Browning & Gordon-Gray, 1999; Camelbeke, 2002; Guarise & Vegetti, 2007; Ahumada & Vegetti, 2009; Reutemann et al.
The grain yield, spikelet
sterility, number of grains per panicle, plant height, number of days to flowering, and 100-grain weight were evaluated by conventional methods.
1]s and subsequently, the screening based on pollen and spikelet
sterility to infer the male parent to be restorer or maintainer which is tedious and involves extra season.
solitary, sessile, compressed, elliptic, 3-5 mm long; each spikelet
has 3-9 fertile florets.
production is influenced by nutrient uptake, especially nitrogen.
The modes of damage to wheat crop were, loopering of tops of wheat plant, poor pollination/fertilization, shattering of spikelet
in early sown wheat crop, mechanical injury to Flag leaf and stem of wheat.
