Influence of growing season, location and planting time on some quality parameters of kabuli chickpea

Abstract

Variability in hundred seed weight (HSW), protein content (PC) and cooking time ( C T ) was determined in the world collection of kabuli chickpea (Cicer arietinum L ) maintained at ICARDA. HSW varied from 8 to 679, PC fiom 143 to 270 g kg-' (14.3 to 27%) and C T f o m 50 to 296 min. Over all observations a coefjicient of correlation of 0.87 (P=O.Ol) was found between HSW and CT. This was not maintained for genotypes of intermediate HS W (25-42 g per 100 seeds). Standard unit heritability was 0.96, 0-37 and 0.68 respectively for HSW, PC and CT, while broad sense heritability was 0.79for HS W and 0.55for PC indicating a surprisingly high degree of heritability of PC in the kabuli chickpea.Growing season had a marked effect on HSW and a lesser effect on PC than did growing location, and genotypelseason and genotypellocation interactions were apparent in both HSW and PC. Since CT and HSW were highly correlated, C T was affected to the same extent as HSW by growing season and location. PC appeared to be the most stable of the three quality parameters, and several lines were identified which maintained a PC significantly higher than the population mean when grown on two locations over two seasons, with low within-genotype coeflcients of variability.Compared with spring planting, winter planting decreased PC by 8 g kg -'whereas HSW increased by 1.2g per 100 seeds.

“…Elde edilen ortalamalar aşağıda ayrı çizelgelerde özetlenmiştir. Erskine et al (1985), mercimek tohumlarının irilik, protein ve pişme kalitesine genetik ve çevresel farklılıkların etkileri ile ilgili çalışmalarında, baklagillerin protein miktarı ve kalitesine çeşitten başka toprak tipi, iklim, yetiştirme yeri ve agronomik uygulamaların etkisinin olduğunu; Singh et al (1986), nohut çeşit, hat ve populasyonuna göre tane su alma oranlarının farklılaştığını, genotipin kendisine has tane karakterlerine sahip olduğunu bildirmişlerdir.

Effects of seeding date and seeding rate on yield, proximate composition and total tannins content of two Kabuli chickpea cultivars

“…Anyway, in this review no data were presented about the effect of agronomic techniques on grain yield, proximate composition and content of secondary compounds. Singh et al (1990) studied the combined effect of growing season, location and planting time on hundred seed weight (HSW), protein content (PC) and cooking time (CT) of different chickpea genotypes. The authors related these quality parameters with environmental conditions and found that winter planting decreased PC by 8 g kg -1 , whereas HSW increased by 1.2 g per 100 seeds as compared with spring planting.…”

Componentes do rendimento, teores de isoflavonas, proteínas, óleo e qualidade de sementes de soja

“…O efeito da temperatura pode explicar as variações na concentração de proteínas, tanto entre locais, como entre anos em um mesmo local (Pípolo, 2002). Singh et al (1990) e Benzain & Lane (1986) relataram efeito positivo entre temperatura e conteúdo de proteínas em grão-de-bico e trigo. Entretanto, Shafii et al (1992) relataram relação inversa entre temperatura e óleo em sementes de canola.…”
