Seed yield of Indian mustard
-
In India, oilseed Brassica are grown over an area of about 6.3 million hectares with an annual production of 7.92 million tones with an average yield of 1304 kg/ha whereas in Rajasthan it was still 1422kg/ha. The severe attack of many diseases not only deteriorates the quality of the seed, but also reduces the oil content considerably. Among the diseases, white rust caused by Albugo candida (Pers. Ex Hook) O. Kuntze, is an important disease of a wide variety of Brassica crops. Its infection causes disfiguring white pustules on leaves, flowers stems and pod leading to yield losses.

Thirty six diverse genotypes of Indian mustard (Brassica juncea L. Czern and Coss.) were evaluated for ten quantitative. The variability indicates that Genotypic coefficient of variation (GCV) was moderate for 50% flowering, days to maturity, total no. of siliqua per plant, biological weight, test weight and seed yield; low for plant height, no. of siliqua on main shoot, no. of seed per siliqua and harvest index.

Ten diverse Indian mustard (Brassica juncea L. Czern and Coss) genotypes suitable for early, timely and late sown condition were crossed in diallel mating design excluding reciprocals with an objective to identify the heterotic crosses. All three type of heterosis (relative heterosis, heterobeltiosis and economic heterosis) were estimated for seed yield and contributing traits.

The present experiment was conducted in on 220 cultivars of mustard to measure the correlation path analysis of agro-morphological traits on yield. Observation of ten agromorphological traits viz. Days to 50% Flowering, Plant height (cm.), No. of primary branches, No. of secondary branches, Days to maturity, Length of siliqua, No. of siliqua / plant, No. of seeds/siliqua, 1000 seed weight (gm.), Yield/plant (gm.) were recorded to analyze the data.

Seed yield was negatively correlated with transpiration rate, stomatal conductance and leaf temperature. However, stomatal conductance showed negative correlation but the response was non-significant and biological yield and harvest index were highly significant with seed yield.

A set of 10 x 10 diallel crosses excluding reciprocals of Indian mustard along with their parents were evaluated in randomized block design with three replications in two set of environments i.e. normal (E1) and moisture stress (E2) in RBD design with three replications during Rabi 2015-16.

Seventy five crosses of Indian mustard [Brassica juncea (L.) Czern & Coss] generated by crossing of fifty lines with five testers in a line x tester mating design, which were used to estimate the standard heterosis potentiality for seed yield, its component traits and oil content. These parents, crosses and checks were sown in randomized complete block design under four environments each replicated thrice at two different locations. Observations were recorded on thirteen different characters.

In the present study, an overall appraisal of GCA effects revealed that RH0735 and BPR349-9 in normal environment and RH0116 and RH0555A in late sown environment were good general combiner for majority of the characters. High GCA effects are related to additive gene effects or additive x additive interaction which represent the fixable genetic component of variation. Hence these parents could be efficiently used for exploiting seed yield.

Combining ability analysis was done for nine parents including five female lines and four testers male with their twenty crosses. Laxmi and RH – 406 was conferred as the great general combiner distinguished for “grain yield per plant” because of its positive GCA impact.

Fifty-five Indian mustard genotypes comprising forty-five hybrids and ten parental genotypes along with a two checks viz., NRCHB-506 and DMH-1 were evaluated for stability parameters of morphological and biochemical characters over the three different environments. Pooled analysis of variance over three environments showed that the genotypic variance when tested against G × E were significant for all the eight characters when tested against pooled error.Pooled deviation effect was significant for all the traits except protein content.

The present study was undertaken during 2013-14 and 2014-15 at Chaudhary Charan Singh research farm Hisar, to find out the effect of date of sowing and nitrogen levels on growth, yield, nitrogen uptake and nutrient use efficiencies in western Haryana. The results revealed that plant height, dry matter accumulation, Siliquae per plant, number of seeds of siliqua and 1000 seed weight decreased with each delay in sowing. The seed yield decreased by 39.8 and 38.7 % over November 15, 24.2 and 24.5% over November 5, 6.89 and 7.

Genetic variability and diversity play a major role in framing successful breeding programme. It is evident that genetically diverse parents are likely to produce high heterotic effects and yield desirable transgressive segregants. Keeping this in view, the present study was conducted to evaluate nature and extent of genetic variability and diversity in Indian mustard [Brassica juncea (L.) Czern. & Coss.].
