Yield Trait and Stability of Chickpea Genotypes for Intensification of Drought-Prone Rice Fallows of South Asia
There is a need for increasing cropping intensity in South Asia including India to ensure food security of burgeoning population. Accordingly, increasing cropping intensity in rainfed rice fallows can be a futuristic strategy. Identification of suitable cultivar and exploration of genetic variability of specific crops/traits are imperative for genetic improvement, drought resistance and yield gain in rice fallows. We evaluated the morphophysiological, yield traits and stability of 15 chickpea genotypes in randomised complete block design for three consecutive years on a drought-prone rainfed condition of Fluvisol in Kanpur, India. Among genotypes, ‘IPC 2014-55’, ‘IPC 2015-44’ and ‘IPC 2011-92’ had 2%–10% higher relative water content (RWC) over ‘ICC-92944’ (check cultivar). These genotypes did not differ for total chlorophyll content, root dry weight and nodule dry weight with ‘ICC-92944’ and ‘KWR 108’ (wider adaptable cultivar of the region). The nitrogen balance index was higher in ‘IPC 2011-92’, ‘IPC 2014-88’ and ‘IPC 2014-55’ by 5%–44% over check cultivar (p < 0.05). The membrane stability index was higher for ‘IPC 2014-55’ (30%, p < 0.05) and ‘IPC 2011-92’ (17%, p < 0.05) than ‘ICC-92944’. ‘IPC 2011-92’, ‘IPC 2014-88’ and ‘IPC 2014-55’ (3 years mean) had 3%–24% higher plant dry weight than ‘ICC-92944’. Notably, ‘IPC 2014-55’, ‘IPC 2015-44’, ‘IPC 2014-88’ and ‘IPC 2011-92’ had higher yield attributes such as pods plant−1 by 9%, grain weight plant−1 by 13% and 100-seed weight by 3% than ‘ICC-92944’ and ‘KWR 108’ (mean of years). These genotypes had higher mean seed yield than ‘ICC-92944’ by 23%–42% and ‘KWR 108’ by 7%–23% (p < 0.05). The yield of ‘IPC 2014-55’, ‘IPC 2015-44’, ‘IPC 2014-88’ and ‘IPC 2011-92’ were stable over years across variable soil and environmental condition as indicated by the genotype × year biplot. Membrane stability index, pods plant−1 and 100-seed weight were the determinants for increased seed yield of chickpea under drought-prone condition. Evidently, genotype ‘IPC 2014-55’, ‘IPC 2015-44’, ‘IPC 2014-88’ and ‘IPC 2011-92’ were better under rainfed rice fallows. These genotypes could be tested under specific drought condition for developing varieties and promoted in rice fallows of South Asia for yield advantage and drought resistance.
期刊介绍:
The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
