Abstract

Context: Crop production in Eastern Himalaya is constrained by combined effects of soil acidity and moisture deficit during post monsoon under a changing climate.

Aim: This study aimed to identify potential buckwheat genotypes and stress mechanisms in hill environments of Meghalaya (India).

Method: Field and microcosm experiments were conducted to study field performance, genotypic variability and physio-morphological efficiency in buckwheat.

Key results: Substantial genetic variability for shoot length (30.3–110 cm), crop canopy distribution (3.0–7.5 number of primary branches), leaf area retention (15.7–60.2 cm2/two leaves), 1000 seed weight (16.2–34.7 g) and seed yield (0.088–1.31 metric tonne (MT)/ha) was observed. Mean grain yield of buckwheat genotypes was 0.446 MT/ha whereas IC13411, IC24298 and IC37305 produced significantly higher seed yield (1.31, 1.28 and 1.14 MT/ha, respectively) accounting to 1.93, 1.87 and 1.67 times higher than average yield (0.680 MT/ha). Genotypes like IC42416, EC323730 and EC218784 have lower crop yields (0.8, 1.02, 0.93 MT/ha respectively). Interestingly, few high yielders (IC13411 and IC24298) exhibited higher photosynthetic rate (46.1 and 32.3 μmol/m2.s), increased stomatal conductance (311.0 and 326.2 mmol/m2.s), leaf chlorophyll (2.47 and 2.55 mg/g fresh weight (FW)) and carotenoids (95 and 106.3 μg/g FW). Chlorophyll a and b ratio (3.3 and 3.0) and total chlorophyll to carotenoids (4.2 and 4.0) were higher in high yielders (IC13411 and IC24298) compared to other low yielders.

Conclusions: Robust root systems, stomatal structure and higher cuticle wax ideally enhanced water use efficiency (WUE) and drought tolerance in high-yielding buckwheat genotypes.

Implications: IC13411 and IC24298 are promising for enhanced productivity in the mountainous ecosystem of Meghalaya.

Keywords: acid soil, drought, hill agriculture, leaf morphology, photosynthesis, stomatal structure, root morphology, yield components.
