“…The soft white spring wheat (Triticum aestivum L.) cv. AC Nanda (Sadasivaiah et al 2000) was used for mutation generation in immature spikes. Plants were grown in a growth chamber in pots containing Redi-earth (W.R. Grace & Co. of Canada, Ontario, Canada) at 23 °C/16 h light (350 µmol m -2 s -2 PPFD) and 19 °C/8 h dark.…”

A wheat (Triticum aestivum L.) immature spike culture system was used to expeditiously generate mutations for use in wheat improvement programs. Wheat immature spikes in culture were treated with three concentrations of ethylmethane sulphonate (EMS) to generate a spike culture derived variant (SCDV) population. EMS in a concentration dependent manner affected seed development in wheat immature spike cultures. Based on the number of seeds produced, inclusion of EMS (25 mM) for three hours in immature spike culture medium generated variants in wheat cv. AC Nanda. The wheat AC Nanda SCDV population showed variation in several phenotypic characters. Flag leaf (length, angle and sheath length), length of first and second internode, spike length, number of spikes, number of seeds per spike and seed weight, showed variation below and above the non-treated controls. A molecular screening technique combining simple sequence repeat (SSR) oligonucleotide primers with high resolution melt (HRM) PCR with EvaGreen was used to identify the variants. Screening for starch branching enzyme IIb (SbeIIb) revealed 75 lines with point mutations. Combining SSR and SbeIIb, a total of 100 Kbp portion of wheat DNA was screened. The estimated mutation frequency in SbeIIb was one per 20.8 Kbp. The spike culture system utilizes very small amounts of EMS for a brief period, thus needs minimal handling of EMS and saves one generation of plant growth in a greenhouse. The morphological variants observed are similar to those reported for seed-derived variants using EMS.

“…The criteria used in the evaluation include grain yield, plant height, maturity, resistance to lodging, shattering and diseases, and end‐use quality characteristics. Widely grown cultivars AC Reed, AC Phil (Sadasivaiah et al, 2000a), and AC Nanda (Sadasivaiah et al, 2000b) were used as checks.…”

“…Cultivars were selected to represent general purpose markets in western Canada for which dry land production of soft white spring wheat could be eligible. AC2000 (DePauw et al 2002) and AC Vista were chosen to represent the Canada prairie spring white (CPSW) class, AC Crystal ) and AC Taber (Knox et al 1992) to represent CPSR, AC Corinne (Humphreys et al 2001) to represent Canada western extra strong (CWES), and AC Reed (Sadasivaiah et al 1993) and AC Nanda (Sadasivaiah et al 2000) to represent CSWSW. AC Reed occupied the majority of acreage at the time and was the industry check cultivar for quality; AC Nanda is later maturing and has a contrasting growth and quality profile to AC Reed (Sadasivaiah et al 1993).…”

“…durum) for the semolina industry (Andy Kovacs, personal communication). CWSWS varieties have been bred for adaptation to irrigated conditions in the western prairies and, therefore, tend to be shorter in stature with very strong straw and resistant to most of the prevalent races of stripe rust and powdery mildew (Sadasivaiah et al 1993(Sadasivaiah et al , 2000(Sadasivaiah et al , 2004a. Production of soft white wheat in dry land regions has been limited for concern a cultivar bred for optimum conditions may not perform well in semi-arid or low productivity environments.…”

. 2008. The influence of moisture regime, N management, and cultivar on the agronomic performance and yield stability of soft white spring wheat. Can. J. Plant Sci. 88: 859Á872. Field studies were conducted for 4 yr (2000Á2003) in southern Alberta to determine the agronomic suitability and yield stability of soft white spring wheat across an array of moisture and fertility regimes. Two soft white spring wheat cultivars (AC Reed and AC Nanda) with contrasting maturity and quality profiles were compared to nine varieties representing the Canada Prairie Spring White, Canada Prairie Spring Red, and Canada Western Extra Strong wheat classes. The cultivars were managed with five varying rates of mid-row banded ammonium nitrate 0, 19, 38, 57, and 76 kg N ha (1 . AC Reed matured earlier than most cultivars except AC Vista, and had the highest average yield. Yield stability analyses showed that AC Reed was well adapted to all environments but AC Nanda was less stable. AC Vista, AC Crystal, and AC Karma had average to good stability, but produced less grain than both AC Reed and AC Nanda. For non-irrigated production, yield was generally optimized at the mid-row banded rate 38 kg N ha(1 of ammonium nitrate. Response to N varied at the irrigated sites, but sites with lower initial soil NO 3 -N levels were responsive through the 76 kg N ha(1 rate. The soft white spring wheat class responded similarly to N in all moisture regimes, but whole-grain protein accumulation was not always lowest in the soft white spring wheat class.This study indicates that long-term sustainable production of soft white spring wheat in semi-arid, non-irrigated environments is possible, and would be most successful if cultivars were selected with yield stability, maturity and protein characteristics similar to AC Reed.
