“…Overall, the grain yield increased substantially with the development of improved varieties. This is in agreement with other findings such as in chickpea, which also reported a significant increase in grain yield of chickpea varieties over the old ones ( Tadesse et al., 2018 ). In another similar study, better seed yield of newly developed soybean cultivars over the first old variety was reported ( Demissew, 2010 ).…”

India’s rainfed sorghum improvement: Three decades of genetic gain assessment for yield, grain quality, grain mold and shoot fly resistance

et al. 2022

Sorghum is a climate-resilient cereal and staple food crop for more than 200 million people in arid and semi-arid countries of Asia and Africa. Despite the economic importance, the productivity of sorghum in India is constrained by biotic and abiotic stresses such as incidences of shoot fly, grain mold and drought. Indian sorghum breeding focused on dual-purpose (grain and fodder), short-duration varieties with multiple resistance/tolerance to pests and diseases and improved nutritional quality (high protein, iron and zinc and low fat). In this context, it is important to ascertain the genetic progress made over 30 years by assessing the efficiency of past achievements in genetic yield potential and to facilitate future genetic improvement. The current study determined the genetic gain in 24 sorghum varieties developed by the national and state level research systems during 1990-2020. The 24 varieties were evaluated for three years (2018-2020) at six locations in Telangana state for yield, nutritional characteristics and tolerance to shoot fly and grain mold. The absolute grain yield genetic gain from the base year 1990 is 44.93 kg/ha/yr over the first released variety CSV 15. The realized mean yield increased from 2658 kg/ha of the variety CSV 15 in 1990s to 4069 kg/ha of SPV 2579 developed in 2020s. The absolute genetic gain for grain mold resistance is -0.11 per year with an overall relative gain of 1.46% over CSV 15. The top varieties for grain yield (SPV 2579, SPV 2678 and SPV 2578), fodder yield (PYPS 2, SPV 2769 and SPV 2679), shoot fly tolerance (PYPS 8, PYPS 2 and SPV 2179), mold tolerance (PYPS 8, PYPS 2 and SPV 2579) and high protein (PYPS 8, PYPS 2 and SPV 2769) were identified for possible scale up and further use in breeding program diversification. The study revealed that sorghum varieties bred with diverse genetic backgrounds such as landraces and with tolerance to pests and diseases had stable yield performance. Application of genomics and other precision tools can double genetic gains for these traits to strengthen sorghum cultivation in rainfed areas serving food and nutrition security.

“…One of the major constraints limiting lentil production in Morocco is the limited use of improved variety certified seeds by farmers.

“…One of the methods widely used to estimate the progress made from genetic gain achieved in plant breeding programs is the regression of the average performance of released varieties for a specific trait in different environments over their years of release (Duvick, 1984). This estimation has been used for several major crops, for instance in wheat (Triticum aestivum L.; Peltonen-Sainio and Peltonen, 1994;De Vita et al, 2007;Giunta et al, 2007;Mladenov et al, 2011, Taghouti et al, 2017Laidig et al, 2017b), barley (Hordeum vulgare L.; Laidig et al, 2017a), chickpea (Cicer arietinum L.; Tadesse et al, 2018), common bean (Phaseolus vulgaris L.; Barili and do Vale, 2016), and soybean [Glycine max (L.) Merr. ; Tefera et al, 2010].…”

Breeding Progress, Adaptation, and Stability for Grain Yield in Moroccan Lentil Improved Varieties

et al. 2019

View full text Add to dashboard Cite

Lentil (Lens culinaris Medik.) is an important grain legume worldwide. It contributes to sustain farming through its ability to fix N in soils and to enhance human nutrition and health thanks to its nutritionally rich grains. In Morocco, it is consumed as staple food by a large proportion of the population. However, the country depends on importation to meet the national demand at the cost of losing valuable currencies. One of the factors limiting lentil production in Morocco is the availability and use of certified seeds of improved varieties. In this research, we aimed at evaluating genetic gain from breeding, adaptation and stability of available improved varieties to make recommendations aiming to enhance their use and adoption by farmers. We studied 9 registered varieties and two candidate lines in 14 different environments for grain yield. All the tested varieties and candidate lines had higher yield than the actual average yield of lentil in Morocco. Significant increase and higher genetic gain over the local check were observed from 1989 to 2018. Up to 35 kg ha−1 yr−1 genetic gain for grain yield was obtained. The yield advantage of improved varieties over the local check increased from 16 to 67% from 1989 to 2018. Most of varieties have wide adaptation and respond positively to the increase of environmental index. The environmental factor in terms of the amount and distribution of rainfall has a determinant effect on grain yield for all varieties and candidate lines. However, differences in the degree of adaptation and stability of these varieties were observed. These results could help draw more attention to lentil in Morocco and define efficient strategies that make the best varieties available for farmers from the perspective of enhancing national production.

“…Our measured genetic gain for Australian lentils between 1988 and 2019 averaged 20 kg ha –1 year –1 or 1.23% year –1 across eight environments. It compares with the rate of 18–27 kg ha –1 year –1 for Ethiopian lentil in two environments ( Bogale et al, 2015 ); 31–35 kg ha –1 year –1 for Moroccan lentil ( Idrissi et al, 2019 ); 11–17 kg ha –1 year –1 for kabuli ( Tadesse et al, 2018 ), and 32 kg ha –1 year –1 for desi chickpea in Ethiopia ( Bekele et al, 2016 ).…”

Australian Lentil Breeding Between 1988 and 2019 Has Delivered Greater Yield Gain Under Stress Than Under High-Yield Conditions

2021

The contemporary lentil (Lens culinaris ssp. culinaris) industry in Australia started in the late 1980s. Yield in farmers’ fields averages 1.2 t ha–1 nationally and has not increased over three decades. Lack of yield progress can be related to a number of non-mutually exclusive reasons: expansion of lentil to low-yielding environments, lack of genetic gain in yield, lack of progress in agronomic practices, and lack of adoption of superior technologies. The aims of this study were to (i) quantify the genetic gain in lentil yield since 1988, (ii) explore the variation in the expression of genetic gain with the environment, and (iii) identify shifts in crop phenotype associated with selection for yield and agronomic adaptation. We grew a historic collection of 19 varieties released between 1988 and 2019 in eight environments resulting from the factorial combination of two sowing dates, two water regimes, and two seasons. Across environments, yield varied 11-fold from 0.2 to 2.2 t ha–1. The rate of genetic gain averaged 20 kg ha–1 year–1 or 1.23% year–1 across environments and was higher in low-yield environments. The yield increase was associated with substantial shifts in phenology. Newer varieties had a shorter time to flowering and pod emergence, and the rate of change in these traits was more pronounced in slow-developing environments (e.g., earlier sowing). Thermal time from sowing to end of flowering and maturity were shorter in newer varieties, and thermal time from pod emergence to maturity was longer in newer varieties; the rate of change in these traits was unrelated to developmental drivers and correlated with environmental mean yield. Genetic gain in yield was associated with increased grain number and increased harvest index. Despite their shorter time to maturity, newer varieties had similar or higher biomass than their older counterparts because crop growth rate during the critical period increased with the year of release. Genotype-dependent yield increased over three decades in low-yield environments, whereas actual farm yield has been stagnant; this suggests an increasing yield gap requiring agronomic solutions. Genetic improvement in high-yield environments requires improved coupling of growth and reproduction.
